hello,

I've tried this:

zxsl:value-of select="saxon:line-number(.)"/>
</xsl:template>

buy gives me the line of the input xml

My suggestion was that you should write an XSLT stylesheet that preprocesses the stylesheet: so that at this time, the stylesheet IS the input XML. That mirrors the way the C preprocessor handles it.


saxon:line-number also requires a version of Saxon that supports it (e.g. Saxon-PE 9.3) and setting the -l option on the command line so that line numbers are maintained.

I need to know the line number in the xslt itself


Many thanks

You could implement the preprocessor easily enough if you are using
Saxon. For example if you use<?line?>  then you can write the
preprocessor as

<xsl:template match="*">
    .. identity template ..
</xsl:template>

<xsl:template match="processing-instruction(line)">
<xsl:value-of select="saxon:line-number(.)"/>
</xsl:template>

To whom it may concern,

in C there's a pre-processor directive

__LINE__

that gives you the line of source where the directive is.

Is there an equivalent in XSLT?

Many thanks

Best regards
