如果元素具有xmlns属性[duplicate]，则Xpath会失败
可能重复：
xPath找不到*
我试图使用xml来解析.COLLADA文件。问题是，如果根标签具有xmlns属性，我似乎无法使用
xpath()
$string = <<<TEST
<?xml version="1.0" encoding="utf-8"?>
<COLLADA version="1.4.1">
<library_materials>
<material id="Material" name="Material">
<instance_effect url="#Material-effect"/>
</material>
<material id="Material2" name="Material">
<instance_effect url="#Material-effect2"/>
</material>
</library_materials>
</COLLADA>
TEST;
$lol = new SimpleXMLElement($string);
print_r($lol->library_materials->xpath("material[@id='Material2']"));
$string = <<<TEST
<?xml version="1.0" encoding="utf-8"?>
<COLLADA xmlns="http://www.collada.org/2005/11/COLLADASchema" version="1.4.1">
<library_materials>
<material id="Material" name="Material">
<instance_effect url="#Material-effect"/>
</material>
<material id="Material2" name="Material">
<instance_effect url="#Material-effect2"/>
</material>
</library_materials>
</COLLADA>
TEST;
$lol = new SimpleXMLElement($string);
print_r($lol->library_materials->xpath("material[@id='Material2']"));

捅瓶啡
$lol = new SimpleXMLElement($string); $lol->registerXPathNamespace('cada', 'http://www.collada.org/2005/11/COLLADASchema'); print_r($lol->xpath("child::cada:library_materials//*[@id='Material2']"));卧沫
