I have a large XML file of this format:
<data jsxid="jsxroot" caseNumber="59878">
<record jsxid="1" poNumber="13-192208" manu="Biotronik" catNumber="101" total="0" />
<record jsxid="2" poNumber="13-192208" manu="Biotronik" catNumber="102" total="0" />
<record jsxid="3" poNumber="13-192208" manu="Biotronik Total" catNumber="" total="1" />
<record jsxid="4" poNumber="13-192211" manu="Biotronik" catNumber="103" total="0" />
<record jsxid="5" poNumber="13-192211" manu="Biotronik Total" catNumber="" total="1"/>
I want to paginate it into groups of 25 or less, and each page must end on a total line (@total="1").
I got as far as inserting a static page number using the following XSL, but that sometimes cuts off in the middle of a poNumber group so the total is on the next page:
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:param name="pagesize" select="25" />
<xsl:template match="data">
<data>
<xsl:for-each select="@*">
<xsl:copy-of select="." />
</xsl:for-each>
<xsl:apply-templates mode="page" select="record[position() mod $pagesize = 1]" />
</data>
</xsl:template>
<xsl:template match="record" mode="page">
<record jsxid="{position()}" >
<xsl:apply-templates select=". | following-sibling::record[position() < $pagesize]" />
</record>
</xsl:template>
<xsl:template match="record">
<xsl:copy-of select="." />
</xsl:template>
Any ideas on how to make sure the last record on each page is a total?
EDIT: I just wanted to clarify what I was doing with the stylesheet I posted. It inserts a placeholder for a page (jsxid = n) every ($pagesize) records. So if pagesize = 5 for a dataset similar to the one I posted, the output is:
<data jsxid="jsxroot" caseNumber="59878">
<record jsxid="1">
<record jsxid="1" poNumber="13-192208" manufacturer="Biotronik" catalogNumber="101" total="0" />
<record jsxid="2" poNumber="13-192208" manufacturer="Biotronik" catalogNumber="102" total="0" />
<record jsxid="3" poNumber="13-192208" manufacturer="Biotronik Total" catalogNumber="" total="1" />
<record jsxid="4" poNumber="13-192211" manufacturer="Biotronik" catalogNumber="103" total="0" />
<record jsxid="5" poNumber="13-192211" manufacturer="Biotronik Total" catalogNumber="" total="1"/>
<record jsxid="2">
<record jsxid="6" poNumber="13-192208" manufacturer="Biotronik" catalogNumber="101" total="0" />
<record jsxid="7" poNumber="13-192208" manufacturer="Biotronik" catalogNumber="102" total="0" />
I'm displaying this data in a matrix in General Interface and using the jsxid to iterate between "pages."
Thanks.
I got as far as inserting a static page number using the following XSL
I don't see that anywhere in the stylesheet you posted. Assuming by pagination you mean assigning a page number to each record, try:
XSLT 1.0
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:param name="pagesize" select="25" />
<xsl:key name="record" match="record" use="@poNumber" />
<xsl:template match="/data">
<xsl:copy>
<xsl:copy-of select="@*" />
<xsl:call-template name="paginate">
<xsl:with-param name="orders" select="record[@total=1]"/>
<xsl:with-param name="page" select="1"/>
<xsl:with-param name="existing-lines" select="0"/>
</xsl:call-template>
</xsl:copy>
</xsl:template>
<xsl:template name="paginate">
<xsl:param name="orders" />
<xsl:param name="page"/>
<xsl:param name="existing-lines"/>
<xsl:param name="current-order-records" select="key('record', $orders[1]/@poNumber)"/>
<xsl:param name="added-lines" select="count($current-order-records)"/>
<xsl:choose>
<xsl:when test="$existing-lines + $added-lines > $pagesize">
<xsl:call-template name="paginate">
<xsl:with-param name="orders" select="$orders"/>
<xsl:with-param name="page" select="$page + 1"/>
<xsl:with-param name="existing-lines" select="0"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:for-each select="$current-order-records">
<record page="{$page}">
<xsl:copy-of select="@*"/>
</record>
</xsl:for-each>
<xsl:if test="count($orders) > 1">
<xsl:call-template name="paginate">
<xsl:with-param name="orders" select="$orders[position() > 1]"/>
<xsl:with-param name="page" select="$page"/>
<xsl:with-param name="existing-lines" select="$existing-lines + $added-lines "/>
</xsl:call-template>
</xsl:if>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
Your input is too small to test this, so ... Note that this will crash if any poNumber has more than 25 records.
Creating a container element for each page is considerably more difficult: a pre-processing pass will be required. Try:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:exsl="http://exslt.org/common"
extension-element-prefixes="exsl">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:param name="pagesize" select="25" />
<xsl:key name="record" match="record" use="@poNumber" />
<xsl:variable name="root" select="/" />
<xsl:template match="/data">
<!-- first-pass -->
<xsl:variable name="index">
<xsl:call-template name="paginate">
<xsl:with-param name="orders" select="record[@total=1]"/>
<xsl:with-param name="page" select="1"/>
<xsl:with-param name="existing-lines" select="0"/>
</xsl:call-template>
</xsl:variable>
<xsl:variable name="index-entry" select="exsl:node-set($index)/entry" />
<!-- output -->
<xsl:copy>
<xsl:copy-of select="@*" />
<xsl:for-each select="$index-entry[@page-start='true']">
<record jsxid="{@page}">
<xsl:variable name="poNumbers" select="$index-entry[@page=current()/@page]/@poNumber" />
<xsl:for-each select="$root">
<xsl:copy-of select="key('record', $poNumbers)"/>
</xsl:for-each>
</record>
</xsl:for-each>
</xsl:copy>
</xsl:template>
<xsl:template name="paginate">
<xsl:param name="orders" />
<xsl:param name="page"/>
<xsl:param name="existing-lines"/>
<xsl:param name="current-order-records" select="key('record', $orders[1]/@poNumber)"/>
<xsl:param name="added-lines" select="count($current-order-records)"/>
<xsl:choose>
<xsl:when test="$existing-lines + $added-lines > $pagesize">
<xsl:call-template name="paginate">
<xsl:with-param name="orders" select="$orders"/>
<xsl:with-param name="page" select="$page + 1"/>
<xsl:with-param name="existing-lines" select="0"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<entry page="{$page}" page-start="{$existing-lines = 0}">
<xsl:copy-of select="$orders[1]/@*"/>
</entry>
<xsl:if test="count($orders) > 1">
<xsl:call-template name="paginate">
<xsl:with-param name="orders" select="$orders[position() > 1]"/>
<xsl:with-param name="page" select="$page"/>
<xsl:with-param name="existing-lines" select="$existing-lines + $added-lines "/>
</xsl:call-template>
</xsl:if>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
To calculate the minimum page size as required by the largest PO, add this at the top level of your stylesheet (outside of any template):
<xsl:variable name="largestPO">
<xsl:for-each select="/data/record[@total = 1]">
<xsl:sort select="count(key('record', @poNumber))" data-type="number" order="descending"/>
<xsl:if test="position()=1">
<xsl:value-of select="count(key('record', @poNumber))" />
</xsl:if>
</xsl:for-each>
</xsl:variable>
Now you just need to compare this to your default page size and pick the larger of the two.
