Checking node position

Hi all,

I essentially have an undifferentiated list of elements (old html) that I need to transform to xml, and the only hooks I have are certain textual consistencies:

<p>textxtxtxt</p>
<p>head1</p>
<p>text_associated_semantically_with_head1</p>
<p>text_associated_semantically_with_head1</p>
<p>head2</p>

etc.

Thus I want to itentify the position of the <p> with text="head1" (ie. 2), the position of <p> with text="head2" (ie.5) so that I can then wrap all <p>s between 2 and 5 with an element in the result tree.

My problem is what XPath expression returns the 'correct' position?
//p[text()=head1] returns "1" (1st occurrence of p with text = head1), as opposed to "2" the position of p which _incidentally_ is head1 amongst all <p>s.

I can, I suppose, pre-process using generate-id() to ascribe and id attribute to each <p> and then do my transformations.... but I'd really like to ties this up in one stylesheet, not two?

Any ideas, anyone??

tia,

DB
