Change tag attribute value with PHP DOMDocument

How can i use PHP DOMElement class to replace the href-value of a HTML-string with a new value?

With jQuery i would have done something like this

$('a[myattr~="myval"]').attr('href','http://www.google.se');

Thought that was the simplest way to explain it.

PHP is different from jQuery in a lot of very significant ways, but to answer your question:

$domelement->setAttribute("href", "http://www.google.se");

You might want to consult the documentation.

I am indeed aware of that jQuery and PHP is very different. However i thought that one line of code says a thousand words ;) – Anton Gildebrand Oct 21 '12 at 17:02
I don't quite get how i should select the DOM elements that i am interested in... – Anton Gildebrand Oct 21 '12 at 17:10
You can use `$domdocument->getElementById("someid")` to retrieve an element within a DOMDocument. – Asad Saeeduddin Oct 21 '12 at 17:17
Well the problem is that it should elements where the rel-attribute contains "attachment". The elements doesn't have any ID. – Anton Gildebrand Oct 21 '12 at 17:26
You should be using XPath in that case. Convert your DOMDocument to a simplexml object and find the relevant node using XPath. – Asad Saeeduddin Oct 21 '12 at 17:28
