Dear Nick,

dynamic evaluation of XPath expressions is not (yet?) available in standard XSLT 2. Have you looked at saxon:evaluate?

I'm trying to get a variant on the XSLT cookbook template to output csv

It uses XSLT 2.0 and parts of it are quite neat.

I like the idea of importing a generic module, and then defining the
columns to export in the importing module.

I want to extend it to hand different delimiters, in the same way, and
also different line terminators.

The next extension is correctly quoting the output if it containts
quotes in strings etc.

So far, I can do this.

However, there is one problem I can't solve.

My input data is not regular, but CSV output needs to be regular. So I
want to defined the column names like this


and the path names to get the data like this

<xsl:variable name="nodepaths" select=" 'tradeid', 'trader', 'currency', 'instrument/isin' " as="xs:string*" />

The interesting part is the isin. To get the path from the input
fragment, it is an xpath.

So if I had

<xsl:variable name="path" select="instrument/isin" as="xs:string"/>


<xsl:variable name="message">

I want to do something like

<xsl:value-of select="$message/$path"/>

and have it return US0123456789

What's the best way?
