I strongly recommend a reference like Mike Kay's _XSLT Programmer's Reference_; that will save you a lot of silly questions.


i'd like to ask for a solution for such test:
   if ((current("part") == 1) && (current("chapter") == 1))
      intro="true";
in xslt.

by current() i mean a function which returns current
position of a tag in xpath tree.

For example, current() is a well-defined XSLT function that does something entirely different, and the logical syntax is nothing like C's.


Try:

<xsl:if test="count(ancestor::part|ancestor::part/../part[1]) = 1 and
              count(ancestor::chapter|ancestor::chapter/../chapter[1]) =
                1">
  <xsl:attribute name="intro">true</xsl:attribute>
</xsl:if>

The count() expression tests if the ancestor in question is the same as the first such at that level. There may be a more efficient way, but it's too late (early?) for me right now.

HTH,
