issue traversing from 3 level down to 3 level up in xml

eruditionist · September 22nd, 2010, 11:54 AM

Here is the xml I am using

<?xml version="1.0" encoding="UTF-8"?>
<root>
<first name="level1" title="Small Business" alt="Small Business" link="/small-business.jsp">
<second name="level2" title="Products and Services" link="/products/small-business.jsp">
<three name="level3" title="Pickup" link="/business-commerical-pick-up/index.jsp"/>
<three name="level3" title="Dropoff" link="/dropoff.jsp"/>
</second>
</first>
<first title="Enterprise" link="/enterprise.jsp">
<second title="Solutions" link="/enterprise/index.jsp">
<three title="Constructions" link="/construction/index.jsp">
<forth title="C Solutions" link="/solutions/index.jsp"/>
</three>
<three title="Healthcare" link="/healthcare/index.jsp">
<forth title="Facility" link="/healthcare-facility-solutions/index.jsp"/>
<forth title="Community" link="/community-solutions.jsp"/>
</three>
</second>
</first>
</root>

I am able to search through all attributes
<xsl:value-of select="//@title = 'Facility'"/>

but once I get hold of this how do I go up to root level to print the tree for example if @title = 'Facility' the print this

Enterprise - Solutions - Healthcare - Facility

Use the ancestor axis e.g.

Code:

<xsl:template match="/">
  <xsl:apply-templates select="//*[@title = 'Facility']"/>
</xsl:template>

<xsl:template match="*[@title]">
  <xsl:value-of select="ancestor-or-self::*/@title" separator=" - "/>
</xsl:template>

The xsl:value-of separator is XSLT 2.0, if you want XSLT 1.0 then use for-each select="ancestor-or-self::*/@title" and output each value.

The above code only prints Enterprise instead of

Enterprise - Solutions - Healthcare - Facility.

Your result does not make sense, unless you used a stylesheet with version="2.0" and run it with an XSLT 1.0 processor or you used a stylesheet with version="1.0" and run it with an XSLT 2.0 processor supporting backwards compatible processing.
When I use Saxon 9, an XSLT 2.0 processor, with the input

Code:

<root>
  <first name="level1" title="Small Business" alt="Small Business" link="/small-business.jsp">
    <second name="level2" title="Products and Services" link="/products/small-business.jsp">
      <three name="level3" title="Pickup" link="/business-commerical-pick-up/index.jsp"/>
      <three name="level3" title="Dropoff" link="/dropoff.jsp"/>
    </second>
  </first>
  <first title="Enterprise" link="/enterprise.jsp">
    <second title="Solutions" link="/enterprise/index.jsp">
      <three title="Constructions" link="/construction/index.jsp">
        <forth title="C Solutions" link="/solutions/index.jsp"/>
      </three>
      <three title="Healthcare" link="/healthcare/index.jsp">
        <forth title="Facility" link="/healthcare-facility-solutions/index.jsp"/>
        <forth title="Community" link="/community-solutions.jsp"/>
      </three>
    </second>
  </first>
</root>

the stylesheet

Code:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="2.0">

<xsl:template match="/">
  <xsl:apply-templates select="//*[@title = 'Facility']"/>
</xsl:template>

<xsl:template match="*[@title]">
  <xsl:value-of select="ancestor-or-self::*/@title" separator=" - "/>
</xsl:template>

</xsl:stylesheet>

the output is

Code:

Enterprise - Solutions - Healthcare - Facility
