Pass file name parameter to xsl stylesheet

[Luke Airig]

I am using the Saxon 6.5.3 engine and I have an xsl stylesheet that merges two files on a date_time field and writes out a tab-delimited flat file. My working version has a hard-coded file name in the xsl file. I dug through the Saxon documenation to find a way to feed a file name param to eliminate the hard-coded file name in the xsl. This version executes but does not appear to do the merge processing and drops the longitude and latitude values. Can anyone give me some insight as to what I am doing wrong with this? My command line run syntax is commented at the bottom.

merge_lrv_gps_and_trans_to_tab_delim.xsl
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xslutput method="text"/> <xsl:variable name="delim" select="' '"/> <!-- tab --> <xsl:variable name="nl" select="' '"/> <!-- newline --> <xsl:variable name="head"> <xsl:for-each select="/root/header/*"> <xsl:value-of select="concat(., $delim)"/> </xsl:for-each> </xsl:variable>

<xsl:template match="/">
<xsl:apply-templates select="root/record"/>
</xsl:template>

<xsl:template match="record">
<!--note: if lrv_gps.xml is in a different directory, you will need to use the relative path or URL--> <!-- select="document('lrv_gps.xml')/root/record[date_time = current/date_time]"/> --> <xslaram name="lrv_gps_file"/> <xsl:variable name="gps" select="document($lrv_gps_file)/root/record[date_time = current/date_time]"/> <xsl:value-of select="$head"/> <xsl:value-of select="concat($gps/longitude, $delim, $gps/latitude, $delim)"/> <xsl:for-each select="*"> <xsl:value-of select="concat(., $delim)"/> </xsl:for-each> <xsl:value-of select="$nl"/> </xsl:template>

</xsl:stylesheet>

<!-- java com.icl.saxon.StyleSheet -o
C:\bin\merged_lrv_gps_and_trans_tab_delim.xml C:\bin\lrv_trans.xml
C:\bin\merge_lrv_gps_and_trans_to_tab_delim.xsl
{lrv_gps_file=lrv_gps.xml}
-->

You're very close. The only problem is that the param is not declared

merge_lrv_gps_and_trans_to_tab_delim.xsl
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xslutput method="text"/>

<xsl:variable name="delim" select="' '"/> <!-- tab -->

The parameter is being passed to the stylesheet and not to the record template as you had written it.
