note 110740 added to function.simplexml-load-file

kannan's note about how colons seem to be special characters in element names, and using hyphens instead (renaming <node:number> to <node-number>), is because of XML namespaces. <?php $xml = simplexml_load_string(" <root xmlns:node='uri:foo'> <node:number>1538-7445</node:number> </root>"); // you might think $xml->node:number would work. no, that's not valid PHP syntax // ah right, of course. so how about echo $xml->{"node:number"}; // nope // (the syntactically-valid way of writing the same thing) // will not work because there is no element named "node:number" // I'll say that again: there is no element named "node:number" // what you want is the element named "number" *in the node namespace* echo $xml->number; // nope // that looks for "number" in the default (empty) namespace // use SimpleXMLElement::children() to switch namespaces echo $xml->children("node", true)->number; // works by the namespace name echo $xml->children("uri:foo")->number; // works by the namespace URI ?> ---- Server IP: 69.147.83.199 Probable Submitter: 173.160.229.61 ---- Manual Page -- http://www.php.net/manual/en/function.simplexml-load-file.php Edit -- https://master.php.net/note/edit/110740 Del: integrated -- https://master.php.net/note/delete/110740/integrated Del: useless -- https://master.php.net/note/delete/110740/useless Del: bad code -- https://master.php.net/note/delete/110740/bad+code Del: spam -- https://master.php.net/note/delete/110740/spam Del: non-english -- https://master.php.net/note/delete/110740/non-english Del: in docs -- https://master.php.net/note/delete/110740/in+docs Del: other reasons-- https://master.php.net/note/delete/110740 Reject -- https://master.php.net/note/reject/110740 Search -- https://master.php.net/manage/user-notes.php
