Hello

can anyone help me with a simple problem, i think!!

[snip]

 The problem i have is that i cant access 1 distict record, without
pulling out data from nodes that are NOT required. I am sure it is
something to do with the contextual node?? however cant work it out!!!

Here's the xsl file.

<xsl:template match="clientlog/customer">

    <xsl:value-of select="@customerid[.='bloggs']"/>
    <xsl:value-of select="//logitem/@logid"/>
    <xsl:value-of select="logitem/date"/>
    <xsl:value-of select="logitem/message"/>
    <xsl:value-of select="logitem/contact/@contactname"/>
</xsl:template>
</xsl:stylesheet>

The only thing you're doing wrong is not accounting for the ordinary operation of the built-in templates, whose job it is to make sure that unless you say otherwise, all data will be copied into the result tree.

A simple way to fix this is by adding a template to match at the top of your tree, selecting only the nodes you want, as in:

<xsl:template match="/"> <!-- matches the root -->
  <xsl:apply-templates select="//clientlog/customer"/>
  <!-- reaches "into" the tree and selects only the nodes you want -->
</xsl:template>

Then your other template does the rest.

At least, that's what I *think* the problem is. (I'm reading between the lines a little. Please forgive me if it's not. If it is, you might want to take some time to study the XSLT processing model and learn what those built-in templates do.)

Good luck,
Wendell
