Another key question

 Hello,

I'm trying to do something with keys and having a bit of trouble. In doing so, I've done some research with some sample data and come up with the following results. I'm using system.xml.

C:\temp\XSLTProject2->
- type XSLTProject2_data.xml
<test>
        <section>
                <title>H1</title>
        </section>
        <section>
                <title>H2</title>
        </section>
        <section>
                <title>H2</title>
        </section>
        <section>
                <title>H3</title>
        </section>
        <section>
                <title>H2</title>
        </section>
        <section>
                <title>H1</title>
        </section>
        <section>
                <title>H2</title>
        </section>
</test>

C:\temp\XSLTProject2->
- type XSLTProject2.xslt
<?xml version="1.0"?>
<xslt:transform xmlns:xslt="http://www.w3.org/1999/XSL/Transform" version="1.0">


        <xslt:key name="sections" match="section" use="generate-id(current())"/>


        <xslt:template match="/">
                <xslt:apply-templates/>
        </xslt:template>

        <xslt:template match="test">
                <test>
                        <xslt:apply-templates select="section"/>

                </test>
        </xslt:template>

        <xslt:template match="section">
                <xslt:variable name="myID" select="generate-id(.)"/>

                <section>
                        <title><xslt:value-of select="title"/></title>
                        <para><xslt:value-of select="$myID"/></para>
                        <para><xslt:value-of select="generate-id(key('sections',
$myID))"/></para>

                </section>
        </xslt:template>


</xslt:transform>

C:\temp\XSLTProject2->
- type out.xml
<?xml version="1.0" encoding="utf-8" ?>
<test>
        <section>
                <title>H1</title>
                <para>XSLTsection120120120</para>
                <para>XSLTsection120120120</para>
        </section>
        <section>
                <title>H2</title>
                <para>XSLTsection121120120</para>
                <para>XSLTsection120120120</para>
        </section>
        <section>
                <title>H2</title>
                <para>XSLTsection122120120</para>
                <para>XSLTsection120120120</para>
        </section>
        <section>
                <title>H3</title>
                <para>XSLTsection123120120</para>
                <para>XSLTsection120120120</para>
        </section>
        <section>
                <title>H2</title>
                <para>XSLTsection124120120</para>
                <para>XSLTsection120120120</para>
        </section>
        <section>
                <title>H1</title>
                <para>XSLTsection125120120</para>
                <para>XSLTsection120120120</para>
        </section>
        <section>
                <title>H2</title>
                <para>XSLTsection126120120</para>
                <para>XSLTsection120120120</para>
        </section>
</test>

Is the result above correct? I get the following result out of MSXML4. MSXML3 is mostly the same as this (MSXML4), except that the first section has a string in the second para that is equal to the string in the first para.

<?xml version="1.0" ?>
<test>
	<section>
		<title>H1</title>
		<para>IDAEAWY</para>
		<para></para>
	</section>
	<section>
		<title>H2</title>
		<para>IDAGAWY</para>
		<para></para>
	</section>
	<section>
		<title>H2</title>
		<para>IDAIAWY</para>
		<para></para>
	</section>
	<section>
		<title>H3</title>
		<para>IDAKAWY</para>
		<para></para>
	</section>
	<section>
		<title>H2</title>
		<para>IDAMAWY</para>
		<para></para>
	</section>
	<section>
		<title>H1</title>
		<para>IDAOAWY</para>
		<para></para>
	</section>
	<section>
		<title>H2</title>
		<para>IDAQAWY</para>
		<para></para>
	</section>
</test>

What should happen?

My main question, is what does 'current()' mean in the context in which I've used it within xsl:key.

I'd like to do something like this:

	<xslt:key name="sections" match="section" use="generate-id(preceding-sibling::section[title = translate(current()/title,'23456789','12345678')][1])"/>


Thanks,

Rich
