Code tried:
<xsl:template match="entry">
<xsl:param name="colc">
<xsl:number level="single" count="entry"/>
</xsl:param>
<cell>
<xsl:attribute name="Name">
<xsl:variable name="rowc">
<xsl:number level="any" count="row"/>
</xsl:variable>
<xsl:if test="contains(preceding-sibling::entry[1],@namest)">
<xsl:value-of select="$colc - 1 +
number(substring-after(preceding-sibling::entry[1]/@nameend,'c')) -
number(substring-after(preceding-sibling::entry[1]/@namest,'c'))"/>
</xsl:if>
<xsl:if test="not(contains(preceding-sibling::entry[1],@namest))">
<xsl:value-of select="$colc - 1"/>
</xsl:if>
<xsl:text>:</xsl:text>
<xsl:value-of select="$rowc - 1"/>
</xsl:attribute>
</xsl:template>
I have declared a param "colc" and i am manipulating according to the
condition. But when i use condition the value of "colc" is changing.
I am unable to understand why the value is changing and how to stop
this change.
Can you explain in plain English what you want to check? You have a
template matching 'entry' elements and then you have an expression
contains(preceding-sibling::entry[1],@namest)
In your posted input there are only two 'entry' elements at all that
have a 'namest' attribute, the first 'entry' element in the first 'row'
element and the first 'entry' element in the second 'row' element. Both
do not have any preceding-sibling::entry so even for the 'entry'
elements having 'namest' attribute I am not sure what you want to check.
The behaviour of contains is defined for such cases
(http://www.w3.org/TR/xpath-functions/#func-contains) but it is rather
difficult to understand what you want to check for if all evaluations of
the expressions against the sample XML result in such edge cases of one
or two arguments being the empty sequence.
