Re: [PHP] SimpleXML and the Single String (SOLVED)
There is another nice way. You can pass a second value to the simple xml constructor which is a class name to be used instead of SimpleXMLElement. You can write your own class that extends SimpleXMLElement and override the magic methods to skip the casting Simon Schick simonsimc...@googlemail.com hat am 22.

To keep the code readable?
$value = $xml-node;

$value = (String)$xml-node;
I like the first one. Plus you handle it to dynamically to the right type
function __get($value)
{
if is float return float casted value
if is boolean ...
and so on

Re: [PHP] simplexml - can it do what I need?
Hi Guys
Thanks for all your input. This forum is great! I can get the attributes OK
but I can't code the checking routing correctly. This is what I have:
Many thanks again for your input. I tried this but it only gives me the data
for each element. I need to be able to access the attributes of the data in
order to select only those elements that I need. This is the code that I
have at present:
?php
$file= 'annnonces.xml';
// load file
$xml = simplexml_load_file($file) or die (Unable to load XML file!);
foreach ($xml-xpath('//lot') as $lot) {
echo $lot-numero_lot, 'type ', $lot-type, $lot-identification, 'br
/';
echo 'Prix maxi: ', $lot-tarif_max, ' Prix mini: ', $lot-tarif_min,
'br /';
foreach( $lot-elements-element as $key = $data ){
$result=((string) $data-attributes());
if ($result='17') {
echo $data;
}
}
}
?
But this just gives the data for every element. Any ideas on how to get just
the data for the element when the attribute is 17?

foreach ($xml-xpath('//lot') as $lot) {

$result=((string) $data-attributes());
if ($result == 1) {
echo Nombre pièces: , $data, 'br /';
}
if ($result == 3) {
echo Surface: , $data, m2, 'br /';
}
if ($result == 7) {
echo Nombre étoiles: , $data, 'br /';
break;
}
}
}
?
Output is:

Hi Shawn
Thanks for answering my query. I have looked at the suggestions:
$xml = simplexml_load_file('file.xml', 'SimpleXMLElement', LIBXML_NOCDATA);
I am/was able to load the file OK and to access the data by iteration.
However, I can't find a way to extract data by attributes. I need something
like $string=element idtype=11 lang=fr label=Description - Etage.
Obviously, that won't work but that's the result I need. How do I get the
data out of one of these elements by specifying its idtype and lang? I've
google for hours on this and for another hour on SimpleXMLElement.

Hi Terry,
look at the PHP.NET documentation. There indicates the use of
simpleXMLElement structures. If you want to extract elements from this
object, please read there how this work. By the way, it would be
interesting to see, how your XML is made. May be is usefull to use
another class like DOM.

Re: [PHP] SimpleXML strange behaviour.
2008/9/9 Mirco Soderi [EMAIL PROTECTED]
Do you know any reason why the following code does work
$xmlOperazioni = simplexml_load_file($xmlFilename);
foreach($xmlOperazioni-operazione as $operazione) {
if($operazione['nome'] == $operazioneRichiesta) {
require($operazione['php']);
break;
}
}
but the following does not
$xmlOperazioni =
simplexml_load_file($impostazioni['root']['configurazione']['generale']['xml_operazioni']);
foreach($xmlOperazioni-operazione as $operazione) {
if($operazione-nome == $operazioneRichiesta) {
require($operazione-php);
break;
}
}
well im guessing thats because youre using the same file and different
accessors, what i mean is that if
$xmlFilename, and
$impostazioni['root']['configurazione']['generale']['xml_operazioni'] refer
to the same xml from above, then obviously this wont work..
this is looking for an attribute, 'nome', $operazione['nome'];
this is looking for a child element, 'nome', $operazione-nome
that is I MUST access childrens of the element operazione as if it was an
array, while (in the same page) the following code does work
$xmlViste =
simplexml_load_file($impostazioni['root']['configurazione']['generale']['xml_composizione_viste']);
foreach($xmlViste-vista as $vista) {
if($vista-nome == $nomeVistaDaMostrare) {
$smarty-assign(intestazione,componenti/.$vista-intestazione);
$smarty-assign(menu,componenti/.$vista-menu);
$smarty-assign(contenuto, componenti/.$vista-contenuto);
$smarty-assign(pie_di_pagina,
componenti/.$vista-pie_di_pagina);
break;
}
}
but the following does not
$xmlViste =
simplexml_load_file($impostazioni['root']['configurazione']['generale']['xml_composizione_viste']);
foreach($xmlViste-vista as $vista) {
if($vista['nome'] == $nomeVistaDaMostrare) {
$smarty-assign(intestazione,componenti/.$vista['intestazione']);
$smarty-assign(menu,componenti/.$vista['menu']);
$smarty-assign(contenuto, componenti/.$vista['contenuto']);
$smarty-assign(pie_di_pagina,
componenti/.$vista['pie_di_pagina']);
break;
}
}
again, this syntax denotes a child element,
$vista-nome
this syntax denotes an attribute
$vista['nome']
that is this time I MUST access the childrens of the element operazione as
if it was an object?
i recommend a review of the example page on simple xml, but yes children are
access via the - notation, you can also use the children() method if its
more convenient for you.

Some clarity on this matter would be great. The current status is closed as bogus. I dunno WHY they think it's bogus, but there it is. Perhaps if you emailed Helly and asked what his thinking was, and asked politely on php-internals for anybody to comment on why it should be that way, you'd get a better response. I don't use XML nor simpleXML enough to really comment, but at first glance, I'd have to say that the auto-creation of a node is pretty wrong. More research might make me change my mind... Suppose, for example, that the XML spec REQUIRES at least one valid node, and your XML is malformed without it. If that were the case, PHP forcing it to be valid by adding a dummy node seems perfectly reasonable. You may want to also consider submitting a patch if you really think it's wrong, and you've managed to find the commit that causes the problem. -- Some people have a gift link here. Know what I want?

I don't think thats the problem - rather I get the impression that
there are references (and or resources) inside these SimpleXML objects
(e.g. the owning 'document') that cannot be serialized. I would suggest
caching the xml string and read that from disk (or where ever your storing
stuff) and creating an object from that whenever you need it. I don't believe
that
you gain much from serializing an object (as compared to creating a new object)
-
when you unserialize you have pretty much the same overhead as when creating an
object
(I may be very wrong on this! - I do know that cloning an object is _much_
faster than
creating one for instance).

Re: [PHP] simpleXML - simplexml_load_file() timeout? [Resolved]
Just replying to my original post as means of a follow up. I have gone ahead
and used Rasmus' code, he was correct in surmising I was only worried about
an overloaded and slow responding site. It would be very atypical for the
site to be down completely.
While the cache code was very interesting, I think it is a bit overkill
considering the low amount of traffic my site receives. What I have done
instead is to write the feed to a local file upon every update. I think it is
more elegant to have an old feed than to have the terse Feed unavailable in
the spot where the headlines should be.
I have tested by setting the timeout to '0' rather than yanking my ethernet
cable and it seems to work well. I just don't have a suitable spare box to
try the ethernet method, and setting the timeout to 0 seems to have the
intended effect anyway.
Again, I just want to thank everybody involved for their time and effort, it
is very much appreciated.
Here is my function now, if anybody is interested:
function getFeed($url) {
$cache_version = $_SERVER['DOCUMENT_ROOT'] . /cache/ . basename($url);
$rfd = fopen($url, 'r');
stream_set_blocking($rfd,true);
stream_set_timeout($rfd, 5); // 5-second timeout
$data = stream_get_contents($rfd);
$status = stream_get_meta_data($rfd);
fclose($rfd);
if ($status['timed_out']) {
$xml = simplexml_load_file($cache_version);

Why do you do this on every request? Why not have a cron job retrieve an
update every 20 minutes or whatnot and stuff it into a database table
for your page to access? Then if the cron fails to retrieve the feed it
can just leave the table as is, and your visitors can happily view
slightly outdated feeds? Additionally this will be so much faster that
your users might even hang around on your site :)

Maybe you can read the contents of the feeds using fsockopen() and

You can just use fopen() to avoid all that.
eg.
$fd = fopen($url);
stream_set_blocking($fd,true);
stream_set_timeout($fd, 5); // 5-second timeout
$data = stream_get_contents($fd);
$status = stream_get_meta_data($fd);
if($status['timed_out']) echo Time out;
else {
$xml = simplexml_load_string($data);
}
As for your caching, make sure you create the cache file atomically. So
how about this:
function request_cache($url, $dest_file, $ctimeout=60, $rtimeout=5) {
if(!file_exists($dest_file) || filemtime($dest_file)
(time()-$ctimeout)) {
$stream = fopen($url,'r');
stream_set_blocking($stream,true);
stream_set_timeout($stream, $rtimeout);
$tmpf = tempnam('/tmp','YWS');
file_put_contents($tmpf, $stream);
fclose($stream);
rename($tmpf, $dest_file);
}
}
That takes the url to your feed, a destination file to cache to, a cache
timeout (as in, fetch from the feed if the cache is older than 60
seconds) and finally the request timeout.
Note the file_put_contents of the stream straight to disk, so you don't
ever suck the file into memory. You can then use a SAX parser like
xmlreader on it and your memory usage will be minimal. You will need
PHP 5.1.x for this to work.
You could also use apc_store/fetch and skip the disk copy altogether.

I dunno about similating a slow connection, but you can write a very
slow server... :-)
my_slow_rss_feed.php
?php
$data = 'nameDarren Kirby/name';
sleep(10);
for ($i = 0; $i strlen($data); $i++){
echo $data[$i];
flush();
sleep(1);
}
?
Of course, that doesn't simulate the slow connection part of it...
If you have 2 machines, you can unplug the network cable, start your
script, then plug the cable in after 5 seconds.
That's gonna make it pretty slow to connect, almost for sure. :-)
If anybody is goofy enough to complain about the performance of
strlen() in the for(...) statement, you're clearly not paying
attention. :-) :-) :-)

Maybe it's too late to say this, but if your real problem is that you
don't want the function reading
the rss feed to block the rest of your page, you can always put the
output of the reading of the feed
on a separate page, and include this through an iframe.

function request_cache($url, $dest_file, $ctimeout=60, $rtimeout=5) {
if(!file_exists($dest_file) || filemtime($dest_file)
(time()-$ctimeout)) {
ini_set('default_socket_timeout',$rtimeout);
$stream = fopen($url,'r');
stream_set_blocking($stream,true);
stream_set_timeout($stream, $rtimeout);
$tmpf = tempnam('/tmp','YWS');
file_put_contents($tmpf, $stream);
fclose($stream);
rename($tmpf, $dest_file);
}
}
Problem solved.

slightly outdated feeds? Additionally this will be so much faster

your users might even hang around on your site :)
This is a very interesting idea, but I am not sure if it is suitable
for me at
this point. First of all, one feed in particular can change in a
matter of
seconds, and I do want it to be as up to date as possible. Secondly,
this is
just for my personal site which is very low traffic, and it is not
inconceivable that getting the feed every 20 minutes by cron would be
_more_
taxing on the network than simply grabbing it per request...
Perhaps, then, you should:
maintain a list of URLs and acceptable age of feed.
Attempt to snag the new content upon visit, if the content is old
Show the old content if the feed takes longer than X seconds.
You'll STILL need a timeout, which, unfortunately, means you are stuck
rolling your own solution with http://php.net/fsockopen because all
the simple solutions pretty much suck in terms of network timeout.

It would be REALLY NIFTY if fopen and friends which understand all

you could have trimmed that down a bit.

$xmlobj-data-parameters-wind-speed returns an int value of 0.
$xmlobj-data-parameters-wind-speed-value gives me an error:

Maybe I'm missing something about XML specifications, but this doesn't seem

http://www.php.net/manual/en/ref.simplexml.php
Here is a code fragment I use:

var_dump($xml);
if (is_object($xml))
{
//first lets make sure we didn't get an ERROR
if ($xml-error)
{
echo An ERROR was encountered\n;

}
I have my XML setup such that if there is an error, I return:
?xml version=1.0 encoding=iso-8859-1 ?
error code=tbd string=user not found. /
this are attributes, which have to accessed differently. and the first
object you get is already the root node (error in your case).
try echo CODE: .((string)$xml['code']).\n;
(not tested, but should work)
chregu
But simple XML will not detect this as illustrated by var_dump($xml)
object(SimpleXMLElement)#1 (0) {
}
However, if I change my output to be:
?xml version=1.0 encoding=iso-8859-1 ?
error
codetbd/code
stringuser not found with those credentials./string
/error
Then I get...
object(SimpleXMLElement)#1 (2) {
[code]=
string(3) tbd
[string]=
string(38) user not found.
}
Notice also that my object is not nested inside an [error] as I would
expect it to be.
So I would expect to get this (in BOTH cases actually):
object(SimpleXMLElement)#1 (1) {
[error]=
object(SimpleXMLElement)#1 (2) {
[code]=
string(3) tbd
[string]=
string(38) user not found.
}
}

Re: [PHP] SimpleXML add a node
@richard
I dunno about that whole try/catch thing, but if you're not going to USE
it to catch the errors, then you might as well be old school and check the
return values of all these functions.
that sounds good, but , so far I know, if the API says that a function _can_
throw an exception, I _must_ catch it. In this case 'importNode',
'appendChild', and 'createElement'. If I'm wrong please correct me.
Since it works once and not the second time, I'd be looking to see if
the XML produced on the first go-around is actually VALID, since, if it's
not, that would cause this problem, I think.
The first time 'dom_import_simplexml' returns a DOMElement, the second a
DOMDocument. I don't know why.
The string version of the first SimpleXML is: (that produces a DOMElement)
?xml version=1.0?config/
The string version of the second SimpleXML is: (that produce a DOMDocument)
?xml version=1.0?configactive/config/
@jason
I'm alredy using the 'dom_import_simplexml' function (line 5, code anexed)
@jochem
'instanceof' used now, thanks for reminding. Also if in this case it wasn't
the prpblem.
last of all, a probalbly readable version of the code:
---
// check if there is a valid simplexml document
if (!($this-configXML instanceof SimpleXMLElement))
$this-createConfigXML();
$dom = new DOMDocument('1.0');
// create a DOMElement from SimpleXML
$domElem = dom_import_simplexml($this-configXML);
if ( $domElem === false ) return false;
echo \n\r.'1:';var_dump($domElem);echo BR\n\r;
try {
// import DOMElement(simplexml) to empty DOMDocument
$domNode = $dom-importNode($domElem,true);
if ( $domNode === false ) return false;
// append the imported node to the DOMDocument
$domNode = $dom-appendChild($domNode);
// create new DOMElement
$domElem = $dom-createElement(($mode? 'softactive':'active'));
// add new Element to DOMElement(simplexml)
$domNode-appendChild( $domElem );
} catch(Exception $e) {
echo 'EXCEPTION: '.$e-getMessage().'BR/';
return false;
}
// redefine old simplexml
$simplexml = simplexml_import_dom($dom);
if ($simplexml === false) return false;
$this-configXML = $simplexml;
echo '2:';echo $this-configXML-asXML();echo BR\n\r;
}
return true;

I dunno about that whole try/catch thing, but if you're not going to USE

errors as normally would - for the old school its business as usual, only this
simester there are a couple of new kids in the class :-).
I'm pretty sure there was alot of discussion about whether to throw exceptions
or trigger errors in the new php5 extensions. I can't actually think of any
place
in php5 or the extensions I use where the engine throws an Exceptions...
at any rate all my Exceptions are userland generated. like for instance when
any object is not of the right class I might throw an Exception.
Exceptions are really cool, but they are not are a replacement for var
error checking.
behold the 'instanceof' keyword. it is good :-)
(free tip: javascript has a 'instanceof' keyword that is
indentical to the php keyword in usage, AFAICT).
the rest (xml) is all french to me :-/

Agreed 100%. No sense in going through the overhead of creating
Exceptions (which are objects BTW) if you're not even going to use it in
any way at all. Exceptions take a lot of work to build / manage so for
small projects it's really not even worth the time.

A good point. Not only that... if you are trying to convert from
simpleXML to DOM then you need dom_import_simplexml()

RE: [PHP] simplexml and xpath
For this simple query simple do a call to $item-date to get your time.
If the query is more complex in reality, do a foreach using xpath. See the
example on Xpath at www.php.net/simplexml

It works like a dream when I'm retrieving information from an XML document, but when I want to insert new tags it screws up. Someone will correct me if I'm wrong, but I don't think you can add elements to the XML file in this way. You can change existing values, but cannot add new elements from what I've seen. It seems pretty intuitive that it would work in the way you describe, so I don't know why it doesn't. ---John Holmes...
