Previous Comments: ------------------------------------------------------------------------ [2010-10-27 12:10:37] paj...@php.net That's an issue in libxml2. PHP uses libxml2, but we don't develop it. No need to duplicate the entry. Will ping one of the dev to see what's going on there. ------------------------------------------------------------------------ [2010-10-27 11:54:46] ivan dot enderlin at hoa-project dot net Description: ------------ XPath (and possibly libxml2) has a bug when selecting attributes with a namespace. We must use the namespace-uri() function to solve this problem whereas using a registered prefix does not work. A bug has been reported to Gnome in 2008: <https://bugzilla.gnome.org/show_bug.cgi?id=562557> but it's still opened and not resolved. Test script: --------------- <?php $xml = '<?xml version="1.0" encoding="utf-8"?>' . "\n\n" . '<foo xmlns="http://ns1"; xmlns:x="http://ns2";>' . "\n" . ' <bar a="b" x:c="d" e="f" g="h" />' . "\n" . '</foo>'; $sxe = simplexml_load_string($xml); $sxe->registerXPathNamespace('', 'http://ns1'); $sxe->registerXPathNamespace('x', 'http://ns2'); echo $xml . "\n\n" . 'â //@* found(' . count($sxe->xpath('//@*')) . ')' . "\n" . 'â //@x:* (x registered as http://ns2) found(' . count($sxe->xpath('//@x:*')) . ')' . "\n" . 'â //@*[namespace-uri() = "http://ns2";] found(' . count($sxe->xpath('//@*[namespace-uri() = "http://ns2";]')) . ')' . "\n"; Expected result: ---------------- <?xml version="1.0" encoding="utf-8"?> <foo xmlns="http://ns1"; xmlns:x="http://ns2";> <bar a="b" x:c="d" e="f" g="h" /> </foo> â //@* found(4) â //@x:* (x registered as http://ns2) found(1) â //@*[namespace-uri() = "http://ns2";] found(1) Actual result: -------------- <?xml version="1.0" encoding="utf-8"?> <foo xmlns="http://ns1"; xmlns:x="http://ns2";> <bar a="b" x:c="d" e="f" g="h" /> </foo> â //@* found(4) â //@x:* (x registered as http://ns2) found(4) â //@*[namespace-uri() = "http://ns2";] found(1) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53181&edit=1
