are the regular expressions over xml structure?

[Oleg Parashchenko <olpa@uucode.com>]

Hello,

are there libraries to work with XML structure using regular expressions?

Something like this, in pseudocode:

rx = xml_re.compile('''(h1, (not h1)*)''')
rx.sub('''<section>\0</section>''', xml_doc)

If the content of xml_doc was

<x>
<h1>Heading 1</h1>
<p>text 1</p>
<p>text 2</p>
<h1>Heading 2</h1>
<p>text 3</p>
</x>

then the substitution should result in:

<x>
<section>
  <h1>Heading 1</h1>
  <p>text 1</p>
  <p>text 2</p>
</section>
<section>
  <h1>Heading 2</h1>
  <p>text 3</p>
</section>
</x>

Any hints are welcome!
