XML help! How to get elements from an xml

Hey, I was wondering how you get certain elements from an xml file.

Say I had

Code:

<title>Hello!</title>



<body>Woop Woop</title>



<footer>Hey there</footer>

How could I just get the <title>Hello</title> From this xml file?

That's not an XML file (more precisely, it's invalid XML) but a good place to start would be to read the PHP manual pages on SimpleXML

I've started to get more into XPath recently, and it is a fantastic way to traverse the nodes! Something like so:

Code:

//span[@class='time']/parent::div

That would select all the span elements where the class is precisely time -- if it's not precise you can use the contains function. Then its parent node of type div.

It's such a beautiful way of doing things!

I would go so far as to call it beautiful but XPath is very useful indeed.

P.S. Why on earth is that a reply to this topic?

As this particular forum is dead! :-( And... and... XPath is useful for this kind of stuff.
