RE: [xsl] Looping and assigning into variable

[Meiyu Lin <MeiyuL@xxxxxxxxxxx>]

Hi Michael,
This is just what I am looking for but I just tried the following:
var categorySelect = new Array(30);
var driverName = new Array(30); 
var driverDesc = new Array(30);

   <xsl:for-each select= "driverlist">
   <comment>
      categorySelect[techInd] = '<xsl:value-of select="category" />'
      driverName[techInd] = '<xsl:value-of select="drivername" />'
      driverDesc[techInd++] = '<xsl:value-of select="driverdesc" />'
	</comment>
   </xsl:for-each> 
   <xsl:for-each select= "bsqapplist">
   <comment>
      categorySelect[appInd] = '<xsl:value-of select="bsqappcategory" />'
      driverName[appInd] = '<xsl:value-of select="bsqappname" />'
      driverDesc[appInd++] = '<xsl:value-of select="bsqappdesc" />'
   </comment>
   </xsl:for-each>

I tried 
      categorySelect[techInd] = <xsl:value-of select="category" />
The results for the vars are undefined.  Could you tell me what did I do
wrong?  Thank you.

Meiyu

Not by trying to update a variable, that's not the way XSLT works.

Do it like this:

<xsl:variable name="commentVar">
  <xsl:for-each select="Header">
    <xsl:value-of select="Comment"/>
  </xsl:for-each>
</xsl:variable>

<Comments>
  <xsl:value-of select="$commentVar"/>
</Comments>

Of course, you might not need a variable at all, you can just do the
xsl:for-each inside the <Comments> element.

In XPath 2.0 / Saxon 7.0, you can just do:

<Comments>
  <xsl:value-of select="Header/Comment" separator=""/>
</Comments>
