Xml

Hello,

I have well-formed xml documents into string variables. I want to use preg_replace to add a defined attribute to every xml tags.

For example replace:

<tag1>
<tag2> some text </tag2>
</tag1>

by:

<tag1 attr="myAttr">
<tag2 attr="myAttr"> some text </tag2>
</tag1>

So I basically need the regex expression to find any start tags and add my attribute, but I'm a complete regex noob.

Thanks, kats
