Get XPath complet de partielle

Question

J'utilise sélénium avec Perl et avoir une étiquette sur la page, pour accéder à cette étiquette j'ai xpath suivant: //*[text()='some here'], le problème que le besoin d'obtenir xpath complet de cet élément, comme /html/body/table/tr/..../any other/and other/, est il y a une méthode au sélénium ou une fonction perl? Vous cherchez une solution perl ou d'autres choses de travail.

Cette XPath 2.0 expression:

string-join(for $node in ancestor-or-self::node() 
      return concat(('@')[$node/self::attribute()], 
          $node/name(), 
          (concat('[', 
            count($node/preceding-sibling::node() 
              [name()=$node/name()]) + 1, 
            ']'))[$node/../node() 
              [name()=$node/name()][2]]), 
      '/') 

Modifier: Shorter expression.

Cette transformation XSLT 1.0 produit une expression XPath pour chaque noeud contenu dans le paramètre $pNode:

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
<xsl:output omit-xml-declaration="yes" indent="yes"/> 
<xsl:strip-space elements="*"/> 

<xsl:template match="node()|@*"> 
    <path> 
    <xsl:call-template name="buildPath"/> 
    </path> 
    <xsl:apply-templates select="node()|@*"/> 
</xsl:template> 


<xsl:template name="buildPath">

    <xsl:variable name="theResult">

    <xsl:for-each select= 
    "$theNode 
    | 
    $theNode/ancestor-or-self::node()[..]">

     <xsl:otherwise> <!-- This node is not an element -->

       <xsl:variable name="numFollowing" 
         select="count(following-sibling::comment())"/> 
       <xsl:if test="$thisPosition + $numFollowing > 0">

lorsqu'il est appliqué sur le document XML suivant:

<div id="entry-1" class="item-asset asset hentry"> 
    <div class="asset-header"> 
    <h2 class="asset-name entry-title"> 
     <a rel="bookmark" href="http://blahblah.com/paper-scissors">Paper Scissors</a> 
    </h2> 
    </div> 
    <div class="asset-content entry-content"> 
    <div class="asset-body"> 
    <p>Paper and scissors</p> 
    </div> 
    </div> 
</div> 

le résultat est une liste des expressions XPath pour chaque noeud du document:

<path>/div</path> 
<path>/div/@id</path> 
<path>/div/@class</path> 
<path>/div/div[1]</path> 
<path>/div/div[1]/@class</path> 
<path>/div/div[1]/h2</path> 
<path>/div/div[1]/h2/@class</path> 
<path>/div/div[1]/h2/a</path> 
<path>/div/div[1]/h2/a/@rel</path> 
<path>/div/div[1]/h2/a/@href</path> 
<path>/div/div[1]/h2/a/text()</path> 
<path>/div/div[2]</path> 
<path>/div/div[2]/@class</path> 
<path>/div/div[2]/div</path> 
<path>/div/div[2]/div/@class</path> 
<path>/div/div[2]/div/p</path> 
<path>/div/div[2]/div/p/text()</path>
