ruby - XPath to select between two HTML comments is not working? -


i'm trying select content between 2 html comments, having trouble getting right (as seen in "xpath select between 2 html comments?"). there seems problem when new comments on same line.

my html:

<html>  ........  <!-- begin content -->  <div>some text</div>  <div>    <p>some more elements</p>  </div>  <!-- end content --><!-- begin content -->  <div>more text</div>  <!-- end content -->  ....... </html>

i use:

doc.xpath("//node()[preceding-sibling::comment()[. = ' begin content ']]           [following-sibling::comment()[. = ' end content ']]")

result:

<div>some text</div> <div>   <p>some more elements</p> </div> <!-- end content --><!-- begin content --> <div>more text</div>

what i'm trying get:

<div>some text</div> <div>   <p>some more elements</p> </div>

if interested in first pair of comments, start looking first comment:

//comment()[.=' begin content ']/following::*[not(preceding::comment()[.=' end content '])]

i.e.:

//comment()[1][.=' begin content ']           <-- first suitable comment     /following::*                             <-- take following nodes          [not(preceding::comment()[.=' end content '])] <-- satisfying condition there no preceding "end comment"
