[TxMt] XSLT question (Context: Markdown)

[Stefan Brantschen]

A slightly off-topic question regarding XSLT (I am extending the  
XHTML-to-LateX template).

I have the following XHTML markup:

<div class="versionhistory">
   <div class="version" v="v1.0" d="2006-05-04" a="SBR">Change  
description v1.0</div>
   <div class="version" v="v1.1" d="2006-05-05" a="SBR">Change  
description v1.1</div>
   <div class="version" v="v2.0" d="2006-05-06" a="SBR">Change  
description v2.0</div>
</div>

and would like to read the value of attribute "d".

Now, with something like

<xsl:template name="get-version-date">
   <xsl:param name="vers" />
   <xsl:value-of select="//div[@class='version'][@v=$vers]" />
</xsl:template>

I can get easily the value of a specific "version div", such as the  
string "Change description v1.0". But how do I write the select  
statement to get "d" of a specific version instead? Or similarly,  
what is the path to read the attribute "content" of a meta tag such as

<meta name="documentclass" content="wtdocument" />

with something like

<xsl:template name="get-meta-value">
   <xsl:param name="tag-name" />
   <xsl:value-of select="/html/head/meta[@name=$tag-name] (*???*)" />
</xsl:template>

Thanks for any help!

With regards
