Why the 2nd test is not working. why the first test only working. How
to get correct number from 4th cell instead of NaN.

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.


That test is below:

                              <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>

The fourth 'entry' element looks like this:
                   <entry align="left" valign="top">Table 1 TH C1 R2</entry>

so @namest is an empty sequence and that way the check
contains(preceding-sibling::entry[1],@namest) gives true as for the contains
function the empty sequence is interpreted as an empty string and for the
second argument being the empty string contains gives true.

So for that 'entry' the template tries to compute
 number(substring-after(preceding-sibling::entry[1]/@nameend,'c'))
which gives NaN as preceding-sibling::entry[1]/@nameend is the empty
sequence, that way substring-after gives an empty string and number('')
gives NaN. That way the whole expression gives NaN.
