Iteration, or copying in XSL, based on a count. How do I do it?
- by LOlliffe
I'm trying to create an inventory list (tab-delimited text, for the output) from XML data. The catch is, I need to take the line that I created, and list it multiple times (iterate ???), based on a number found in the XML. So, from the XML below:
<?xml version="1.0" encoding="UTF-8"?>
<library>
<aisle label="AA">
<row>bb</row>
<shelf>a</shelf>
<books>4</books>
</aisle>
<aisle label="BB">
<row>cc</row>
<shelf>d</shelf>
<books>3</books>
</aisle>
</library>
I need to take the value found in "books", and then copy the text line that number of times. The result looking like this:
Aisle Row Shelf Titles
AA bb a
AA bb a
AA bb a
AA bb a
BB cc d
BB cc d
BB cc d
So that the inventory taker, can then write in the titles found on each shelf. I have the basic structure of my XSL, but I'm not sure how to do the "iteration" portion.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs"
xmlns:xd="http://www.oxygenxml.com/ns/doc/xsl" version="2.0">
<xsl:output omit-xml-declaration="yes"/>
<xsl:variable name="tab" select="'	'"/>
<xsl:variable name="newline" select="' '"/>
<xsl:template match="/">
<!-- Start Spreadsheet header -->
<xsl:text>Aisle</xsl:text>
<xsl:value-of select="$tab"/>
<xsl:text>Row</xsl:text>
<xsl:value-of select="$tab"/>
<xsl:text>Shelf</xsl:text>
<xsl:value-of select="$tab"/>
<xsl:text>Titles</xsl:text>
<xsl:value-of select="$newline"/>
<!-- End spreadsheet header -->
<!-- Start entering values from XML -->
<xsl:for-each select="library/aisle">
<xsl:value-of select="@label"/>
<xsl:value-of select="$tab"/>
<xsl:value-of select="row"/>
<xsl:value-of select="$tab"/>
<xsl:value-of select="shelf"/>
<xsl:value-of select="$tab"/>
<xsl:value-of select="$tab"/>
<xsl:value-of select="$newline"/>
</xsl:for-each>
<!-- End of values from XML -->
<!-- Iteration of the above needed, based on count value in "books" -->
</xsl:template>
</xsl:stylesheet>
Any help would be greatly appreciated. For starters, is "iteration" the right term to be using for this?
Thanks!
