Re: [xsl] assigned variable value is changing

2009-08-03 03:46:51
Hai,

In the Name attribute i am capturing column number: row number.

Check the row[2]. In that we are having only 2 <entry>s instead of 3
because of the colspan.
So in my output i am increasing the column number of the 2nd <entry>
by the colspan value.

so for 2nd entry the value of @Name  is 2:1

Up to here the code is working correctly. after that in the column
number i am getting NaN. Even though i have included test conditions.

Regards,
Ganesh

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.
