Here's one way:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<table border="1">
<tr>
<th>Node</th><th>Start</th><th>End</th>
</tr>
<xsl:apply-templates/>
</table>
</body>
</html>
</xsl:template>
<xsl:template match="top">
<xsl:for-each select="descendant::reg">
<xsl:choose>
<xsl:when test="position() = 1">
<tr>
<td><xsl:value-of select="."/></td><td>1</td><td><xsl:value-of
select="@count"/></td>
</tr>
</xsl:when>
<xsl:otherwise>
<tr>
<td><xsl:value-of select="."/></td><td><xsl:value-of
select="sum(preceding::reg/@count) + 1"/></td><td><xsl:value-of
select="sum(preceding::reg/@count) + @count"/></td>
</tr>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
I'm sure there are other ways (in fact, I have already thought of
another).

[xsl] How to do this without updating a variable?
Hi,
I have seen past postings about the fact that variables cannot be
updated. But I'm not sure how
to solve the following problem without variable update!
Input:
<top>
<a>
<reg count="5"> A0 </reg>
<reg count="10"> A1 </reg>
</a>
<a>
<reg count="10"> A2 </reg>
</a>
</top>
Output:
Node : start end
A0 : 1 - 5
A1 : 6 - 15
A2 : 16 - 25
--------------------------
So basically output of any node <reg> is based on all the <reg> nodes that
have been processed
before it. If I could use a temporary variable, I would have just kept a
running total of the
total "count" prior to processing that node.
Could someone suggest a solution or give me some pointer?
Thanks,
Anupam.
