(PHP) How do I get XMLReader behave like SimpleXML with Xpath? (Large directory like XML file)
- by AESM
So, I've got this huge XML file (10MB and up) that I want to parse and I figured instead of using SimpleXML, I'd better use XMLReader. Since the performance should be way better, right? But since XMLReader doesn't work with XPath...
The xml is like this:
<root name="bookmarks">
* <dir name="A directory">
<link name="blablabla">
<dir name="Sub directory">
...
</dir>
* </dir>
* <link name="another link">
</root>
With SimpleXML combined with Xpath,
I would simple do like:
$xml = simplexml_load_file('/xmlFile.xml');
$xml-xpath('/root[@name]/dir[@name="A directory"]/dir[@name="Sub directory"]');
Which is so simple.
But how do I do this with just using XMLReader?
Ps.
I'm converting the resulting node to DOM/SimpleXML to get its inner contents.
Like this:
$node = $xr-expand();
$dom = new DomDocument();
$n = $dom-importNode($node, true);
$dom-appendChild($n);
$selectedRoot = simplexml_import_dom($dom);
Is this ok?
...
Thanks!
