regexp to add attribute in any xml tags

regexp to add attribute in any xml tags  using -'php,xml,regex'

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:

<tag2> some text </tag2>


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

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

OK, for those reading these lines and are still interested about using the regex way for some reasons, here is how to do it:

$xml_data= preg_replace('/(<[A-Za-z0-9\-\_]+[^>]*)>/u','\1 attr="myAttr">',$xmlData);

But, as discussed earlier, use that one with caution! Use it only on XML source that you know won't be broken (see soulmerge post about that)
