I reduced the row in your sample from 117 to 7 and added the missing
namespace.
Also I added an "X" to the Data content for the rows you are interested to
see.
This allows for easier result verification.
$ xsltproc karl.xsl karl.xml
<Cell xmlns:ss="foo"><Data>YES X</Data></Cell>
<Cell xmlns:ss="foo"><Data>YES X</Data></Cell>
<Cell xmlns:ss="foo" ss:Index="7"><Data>NO X</Data></Cell>
$
$ cat karl.xsl
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ss="foo"
<xsl:output omit-xml-declaration="yes"/>
<xsl:template match="/root/Row">
<xsl:variable name="row" select="7"/>
<xsl:for-each select="Cell">
<xsl:variable name="last-index"
select="preceding-sibling::Cell[@ss:Index][1]"/>
<xsl:if
test="(@ss:Index = $row) or
(not($last-index) and (position() = $row)) or
($last-index and
(count
(preceding-sibling::Cell
[$last-index = preceding-sibling::Cell]
) + $last-index/@ss:Index + 1 = $row
)
)"

Subject: [xsl] Selecting a particular node of an XML generated from Excel
Hello,
I have a requirement where I am not sure of the best possible solution. The
XML is generated from Excel. The problem is with missing rows which makes
it difficult to select a particular node. Better I explain using this
sample XML: [Pls ignore any case mismatch or spell mistakes]
<root>
<Row>
<Cell><Data>u1</Data></Cell>
<Cell><Data>13.7 billion years ago</Data></Cell>
<Cell><Data>Hydrogen and helium nuclei form in the first three
minutes...</Data></Cell>
<Cell ss:Index="107"><Data>107</Data></Cell>
<Cell><Data>108</Data></Cell>
<Cell><Data>109</Data></Cell>
<Cell ss:Index="115"><Data>115</Data></Cell>
<Cell><Data>116</Data></Cell>
<Cell><Data>YES</Data></Cell> <!-- this is 117th row. But position
() != 117 -->
<Cell><Data>118</Data></Cell>
</Row>
<Row>
<Cell><Data>u2</Data></Cell>
<Cell><Data>2 million yearsgo</Data></Cell>
<Cell><Data>blahlah</Data></Cell>
<Cell><Data>1</Data></Cell>
<Cell><Data>2</Data></Cell>
<!-- SO MANY ROWS HERE -->
<Cell><Data>YES</Data></Cell> <!-- THIS IS 117th row (Cell) i.e.
position() = 117 -->
<!--GAIN SO MANY ROWS HERE -->
<Cell><Data>199</Data></Cell>
<Cell><Data>200</Data></Cell> <!--ASSUME THIS IS 200TH ROW -->
</Row>
<Row>
<Cell><Data>u3</Data></Cell>
<Cell><Data>20th century</Data></Cell>
<Cell><Data>blah blah</Data></Cell>
<Cell ss:Index="117"><Data>NO</Data></Cell> <!-- THIS IS 117th
row But position() != 117 -->
<Cell ss:Index="199"><Data>119</Data></Cell>
</Row>
</root>
The excel to xml convertion results in empty excel columns getting stripped
out in the resulting <Cell>. And so, the number of <Cell>'s vary for each
<Row>. Now, if I want to select a particular <Cell>, say 117th <Cell>, I
need to check any @ss:Index exist and if so, count() the number of the
preceding-sibling's + the preceding @ss:Index value. So, for 117th Cell
value,
(A) in Row 1, 2nd <Cell> of @ss:Indiex is 117th
(B) in Row 2, position() = 117 is the required one
(C) in Row 3, @ss:Indiex matching 117
(D) if none matching found, ignore
In my requirement, I need to select the N-th <Cell> value and check whether
it is 'yes' or 'no' and then process. I am trying approach something like
this (incomplete)
<xsl:for-each select="Cell">
...
<xsl:variable name="last-index " select="preceding-sibling::Cell
[@ss:Index][1]"/>
<!-- the ABOVE giver the last <Cell>'s ss:Index value.Now I need to do
something like count(preceding-sibling::Cell[@ss:Index][1]) - this may be
wrong, but here is what I having trouble and need suggestions and best
approach to solve this, to select N-th <Cell>, where N is known and can be
1 to X (=max possible value). Thanks in advance!. Regards,karl
