#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:
---
Movie One
Movie Two
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:
Movie Two
Actual result:
--
Movie One
Movie Two

#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
elements, no whether where they are - but only under the current item
(whatever it might be)?
Reproduce code:
---
1
2
3
4
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
