Hi Ken and Martin,
Apparently in my attempt to simplify this problem when I asked for help earlier, I did not do what Einstein recommended: "Make everything just simple enough, but not too simple." However, I was able to adapt Martin's code to acquire the information I needed, but now could use a bit more help parsing it. This time, I'll give you all the facts. In my modification, I write to the variable "$value" that contains all of the values related to the sequence of se-tenant <Values> currently of interest. My problem now is that I do not know how to use tokenize() or write regex expressions, if that is the correct method, so that I can output the needed XHTML. My modification of Martin's code: <xsl:variable name="values"> <xsl:for-each-group select="../Stamp" group-by="Formats/@se-tenant"> <xsl:for-each-group select="current-group()" group-by="string-join(Value/@*, '.')"> <xsl:value-of select="current-grouping-key()"/> <xsl:value-of select="Value/@*/concat('=', local-name(), ';')"/> </xsl:for-each-group> </xsl:for-each-group> </xsl:variable> The variable will contain strings similar to this one that I actually extracted from the working code: "3.60=kc-value; =h-value;5=kc-value;6=kc-value;8=kc-value;" This string is exactly what I wanted earlier and was unable to describe acurately. My problem: I now need to tokenize these strings (or break them into usable substrings) so that I can produce the output XHTML . I only need to pay attention to the digits on the left of '=' and the unit-name (kc-value, h-value) on its right. The substring (token) separator is ';' "3.60=kc-value;" is transformed to: <a "href="../aval/3-60.htm">3.60kc</a> " =h-value;" has no digits in front of the '=' and thus must be ignored (the needed information was actually absorbed by the previous token) "5=kc-value;" is transformed to: <a href="../aval/5.htm">5kc</a> "6=kc-value;" is transformed to: <a href="../aval/6.htm">6kc</a> "8=kc-value;" is transformed to: <a href="../aval/8.htm">8kc</a> Can you show me how to do this?

Is that assumption correct? Yes, sorry about that mistake. The string-join assembles the values of all attributes into one string to have some key value for grouping the items. -- Martin Honnen --- MVP Data Platform Development http://msmvps.com/blogs/martin_honnen/
