XSL-FO Document: Inserting a break-before="page" attribute in a concrete fo:table-row
I have an XSL-FO document. This document has a lot of fo:table nested. There is an inner fo:table that has 9 columns and a lot of rows, in this example, first row for table header and other rows, from 1 to 20 for content. In the example below you can see that as a comment, for each FOPTable (fo:table) it is indicated a unique identifier, but this identifier is not always the same for the same table. It is generated randomly by the application that creates this XSL-FO document.
My question is: I want to find the table which has its first column header value set to HEADER_COL1 (this value is always the same), in this example, table identified with id:997 (rember that I cannot search for table according to this identifier since it changes randomly each time application creates the XSL-FO document). Once I have found the desired table I want below:
- How can I insert an attribute break-before="page" for a concrete fo:table-row item?
- I want to get the number of rows that this inner table has.
For example:
For example, If I want to insert this attribute for the 15th fo:table-row item, how can I do this? I want a parametrized generic method that take as an argument a number indicating the fo:table-row where to put this attribute.
I know that I can read the XSL-FO document using below:
string xmlFile = File.ReadAllText(@"C:\Temp\MyXSLFO.xml");
XmlDocument xdoc = new XmlDocument();
xdoc.LoadXml(xmlFile);
But once loaded i have no idea on how to do this.
Note: I am using Visual Studio 2008, C# and .NET 3.5.

Taking your data and removing all the cells and other non-important content, one could simply apply an identity XSL to the XSL FO and modify only the target row.
starting with this XML:
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
<fo:page-sequence force-page-count="no-force" master-reference="first" initial-page-number="1">

And applying this XSL which outputs everything as is, except for a template that inserts a page-break on the 12th row in the target table:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
version="2.0">
<xsl:param name="breakrow" select="12"/>
<xsl:template match="fo:table-row">
<xsl:variable name="rowcnt" select="count(preceding-sibling::fo:table-row)"/>
<xsl:choose>
<xsl:when test="parent::fo:table-header">
<fo:table-row>
<xsl:apply-templates/>
</fo:table-row>
</xsl:when>
<xsl:when test="$rowcnt = $breakrow and ancestor::fo:table[1]/fo:table-header/fo:table-row[1]/fo:table-cell[1]/fo:block/text() = 'HEADER_COL1'">
<fo:table-row break-before="page"/>
</xsl:when>
<xsl:otherwise>
<fo:table-row/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@*"/>
<xsl:apply-templates select="node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
The result is this:

I passed in 12 as a parameter and assumed that you had only one place ... the 12th row. You can certainly use "mod" and do every 12th row or whatever you desire.
Like for instance:
<xsl:when test="$rowcnt mod $breakrow = $breakrow - 1 and ancestor::fo:table[1]/fo:table-header/fo:table-row[1]/fo:table-cell[1]/fo:block/text() = 'HEADER_COL1'">
And of course you can just add to the rows to get all the cell content output.
