Strings to Elements

iceandrews · June 18th, 2010, 03:00 PM

Maybe it's Friday and I'm not thinking clearly, but I'm struggling with a little problem. I have a string of strings separated by a delimiter. I would like to take the set of strings and convert each into an element node in a variable tree. There could be any number of strings in the set from 1 to n. The resulting tree would that many element nodes as well.

The input string comes from a parameter as the following:

Code:

<xsl:param name="StringSet" select="'First,Second,Third'"/>

The desired output looks something like this:

Code:

<xsl:variable name="stringTree" >
     <Strings>
         <String>First</String>
         <String>Second</String>
         <String>Third</String>
     </Strings>
</xsl:variable>

Any suggestions as to parse the input string to create this kind of tree? On a good day, I feel like I should be able to do this in my sleep :) Using Saxon 8.9 XSLT 2.0.

Thank you.

I'm not smart :) I figured it out. Thank you anyway.

Code:

<xsl:variable name="CodeList">
       <xsl:element name="Codes">
           <xsl:for-each select="tokenize($StringSet,',')">
               <xsl:element name="Code">
                   <xsl:value-of select="." />
               </xsl:element>
           </xsl:for-each>
       </xsl:element>
</xsl:variable>

Note that xsl: element is only necessary if you need to compute the element name or namespace, otherwise you can simply use a literal result element e.g.

Code:

<xsl:variable name="CodeList">
   <Codes>
       <xsl:for-each select="tokenize($StringSet, ',')">
           <Code>
              <xsl:value-of select="."/>
           </Code>
       </xsl:for-each>
    </Codes>
</xsl:variable>
