RE: Question about xpath

[Mike Brown <mbrown@xxxxxxxxxxxxx>]

There are a few things wrong with your stylesheet.

<xsl:variable name="view" select="document('views.xml')/view[@name='my
view']"/>

By using the '@' you are implying that name is an attribute of view. But in
your XML, it is a child element. Use
select="document('views.xml')/view[name='my view']" (or, for clarity,
[./name='my view'] )

Replace the hyphen in $current-contract with an underscore. Hyphens are not
allowed in variable names.

Because one of your view columns is 'stock/name', you'll need to handle that
case specially. You can assign the string 'stock/name' to a variable, but
you can't use that in an XPath expression as if it were a node-set. You also
need to pick the child element of contract with the same name as the view
column. So, replace this:

  <xsl:for-each select="$view/column">
    <xsl:value-of select="$current-contract/text()"/>
  </xsl:for-each>

With this:

  <xsl:for-each select="$view/column">
      <xsl:variable name="current_column" select="."/>
      <xsl:choose>
          <xsl:when test=".='stock/name'">
              <xsl:value-of select="$current_contract/stock/name"/>
          </xsl:when>
          <xsl:otherwise>
              <xsl:value-of
select="$current_contract/*[name(.)=$current_column]"/>
          </xsl:otherwise>
      </xsl:choose>
   </xsl:for-each>

If that's not the exact solution, it should be pretty close.
