Hi Scott,

I would expect your XSLT to look something like this:

<xsl:template match="TABLE">
  <table>
    <xsl:apply-templates/>
  </table>
</xsl:template>

<xsl:template match="DROW">
  <tr>
    <xsl:apply-templates/>
  </tr>
</xsl:template>

<xsl:template match="OBJECT">
  <td>
    <!-- first, whatever you want to do to show empty objects -->
    ...
    <!-- then, continue tree traversal for the data content
         and the nested tables by applying templates -->
    <xsl:apply-templates/>
  </td>
</xsl:template>

With appropriate attribute processing for copying in the widths, borders etc.

See, Jarno said it was simple.... Note also that "closing tags" are not an issue here ... nor are they ever unless you are writing unorthodox XSLT for some peculiar reason. (And even then you might be writing them, but can't read them: as a proficient XSLT programmer you know that the data model knows nothing of "tags".)

The question is, since you say you know XSLT well, but ask for help with XPath ... but this is a straightforward, XSLT-default descent (and therefore all the XPath is built in) ... what are we missing?

Cheers,
Wendell

Desired output is xhtml<-creating xhtml output I have no problem with. The problem I am stuck on is given the above nested input file I need to know when to transform the closing </TABLE> element to </table> in my transformed output. Once I have completed that task I need to be able to use the same logic for the DPROW and OBJECT structure.

Wendell,

thanks for the response. I typically create xhtml output that is of the standard flavor of:

<body>

<table>
<tr><td></td></tr>
....
..
etc





</table></body>

For the included xml snippet I added to this post that contains multiple table elements both nested and non-nested I need to create an output structure that different from what I am use to creating.

<body>

<table>
<tr><td></td></tr>
</table><table><tr><td></td><td></td></tr><table><tr><td></td></tr></table></table>

</body>
