Re: problem using self::node() in for-each

Hi Garrett,
  Please try -

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="text" version="1.0"
encoding="UTF-8" indent="yes"/>
        
<xsl:template match="/root">
    <xsl:for-each
select="information[(_at_)type='info']/instance">
      <xsl:variable name="source-id"
select="inf_source_id" />
      <xsl:value-of select="inf_text" /> -
<xsl:value-of
select="/root/information[(_at_)type='source']/instance[inf_source_id
= $source-id]/inf_name" /><xsl:text>&#xa;</xsl:text>
    </xsl:for-each>
</xsl:template>
        
</xsl:stylesheet>

Regards,
Mukul

I have an XML document with the following structure:

XML Input

<root>
    <information type="source">
        <instance>
            <inf_type>source</type>
            <inf_source_id>1</id>
            <inf_name>Source 1</name>
        </instance>
        <instance>
            <inf_type>source</type>
            <inf_source_id>2</id>
            <inf_name>Source 2</name>
        </instance>
    </information>
    <information type="info">
        <instance>
            <inf_type>info</type>
            <inf_source_id>2</source_id>
            <inf_text>Information 1</text>
        </instance>
        <instance>
            <inf_type>info</type>
            <inf_source_id>1</source_id>
            <inf_text>Information 2</text>
        </instance>
        <instance>
            <inf_type>info</type>
            <inf_source_id>1</source_id>
            <inf_text>Information 3</text>
        </instance>
        <instance>
            <inf_type>info</type>
            <inf_source_id>2</source_id>
            <inf_text>Information 4</text>
        </instance>
        <instance>
            <inf_type>info</type>
            <inf_source_id>2</source_id>
            <inf_text>Information 5</text>
        </instance>
        <instance>
            <inf_type>info</type>
            <inf_source_id>1</source_id>
            <inf_text>Information 6</text>
        </instance>
    </information>
</root>

The inf_source_id in the <information type="info">
refers to the 
inf_source_id in the <information type="source">
i.e. Information 1 has inf_source_id of 2 meaning it
came from Source 2.

I'm trying to output all the inf_text using
xsl:for-each along with the name 
of the source it has a reference to through
inf_source_id.

e.g.

Information 1 - Source 2
Information 2 - Source 1
Information 3 - Source 1
Information 4 - Source 2
Information 5 - Source 2
Information 6 - Source 1


However, I can't get the XPath expression to select
the correct source node 
using the inf_source_id from the current node to
work.
I've used this method before except not in
<xsl:for-each> and it works fine.


XSLT

<xsl:template name="handleInformation">

    <xsl:variable name="info"

select="/root/information/instance[inf_type='info']"/>


    <xsl:for-each select="$info">

        <xsl:variable name="inf_source" 
select="/root/information/instance[inf_type =
'source' and (inf_source_id = 
./inf_source_id)]/inf_name"/>

        <xsl:call-template name="printInformation">
            <xsl:with-param name="source"
select=$inf_source"/>
            <xsl:with-param name="text"
select=./inf_text"/>
        </xsl:call-template>

    </xsl:for-each>

</xsl:template>

Thanks,

Garrett
