[Webtest] iteration over all links in a page

[Brian Hubbard]

Hi,
 I want to be able to check that all the links on a web page have valid links.
 As the pages are generated automatically the number and urls must be discovered
in the page itself.
 I have attempted to do this with a combination of storexpath and repeat, í.e.

 <steps>
  <invoke ...>
  <storexpath xpath="count(//a/@href)" property="n_links"/>
  <repeat count="#{n_links}">
   <storexpath xpath="//a[#{count}+1]/@href" property="link"/>
   <invoke url="#{link}/">
  <repeat/>
 <steps/>

 This gets the number of links correctly, but the xpath //a[n] fails for
anything other than 1. My understanding is that //a[1]/@href should return the
first value of href for the first occurance of the tag "a", //a[2]/@href should
return the value for the second "a" tag within the document and so on.

 Why doesn't this work?
 Is there a better way to achieve this?

 Thanks in Advance,
  Brian
