#42437 [NEW]: Results from xpath() cannot be deleted
From: guenther dot stadler at gmx dot net
Operating system:
PHP version: 5.2.3
PHP Bug Type: SimpleXML related
Bug description: Results from xpath() cannot be deleted
Description:
Elements of the array returned by xpath() cannot be deleted.
I can change those elements, but deleting is impossible.
How can I delete a node returned by xpath()? Is there a way to find out
where the node I found is within the whole xml tree?
Thanks, Günther.
Reproduce code:
---
?php
$xmlstr = XML
?xml version='1.0' standalone='yes'?
root
movieMovie One/movie
movieMovie Two/movie
/root
XML;
$xml = new SimpleXMLElement($xmlstr);
$movs = $xml-xpath('//movie');
// Trying to delete the reference returned by xpath
unset($movs[0]);
// $movs[0] = NULL; doesn't work either
// No changes
echo $xml-asXML();
?
Expected result:
?xml version=1.0 standalone=yes?
root
movieMovie Two/movie
/root
Actual result:
--
?xml version=1.0 standalone=yes?
root
movieMovie One/movie
movieMovie Two/movie
/root

#42348 [NEW]: xPath beginning with // searches whole document
From: guenther dot stadler at gmx dot net
Operating system:
PHP version: 5.2.3
PHP Bug Type: SimpleXML related
Bug description: xPath beginning with // searches whole document
Description:
When using // at the beginning of an xpath-query, not only the children of
the current SimpleXMLElement are searched (as stated in the manual), but
the whole XML document instead.
(So, actually, it might only be a documentation issue...)
If this is expected behaviour, how is one supposed to search all bar
elements, no whether where they are - but only under the current item
(whatever it might be)?
Reproduce code:
---
?php
$xmlstr = XML
?xml version='1.0' standalone='yes'?
root
foo id=foo_1
node
bar1/bar
bar2/bar
/node
/foo
foo id=foo_2
node
bar3/bar
bar4/bar
/node
/foo
/root
XML;
$xml = new SimpleXMLElement($xmlstr);
$foo_list = $xml-xpath('//foo');
$foo = $foo_list[0]; // now we have the node with id=foo_1
$bar_list = $foo-xpath('//bar');
foreach($bar_list as $this_bar)
echo $this_bar ;
?
Expected result:
1 2
Actual result:
--
1 2 3 4
