filemaker xml export via xslt

Question

I'm trying to export some data from our Filemaker Database and transform it via XSLT

I have got most of the way but am getting stuck at some nested data:

Current structure of the XML output is:

    <?xml version="1.0" encoding="UTF-8"?>

    <DATABASE DATEFORMAT="D/m/yyyy" LAYOUT="" NAME="bubbles.fp7" RECORDS="34604" TIMEFORMAT="k:mm:ss "/>

My XSL is working to a certain extent, but I can't quite get it to pick out each of the images:

    <?xml version="1.0" encoding="utf-8"?>
    <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fmp="http://www.filemaker.com/fmpxmlresult" version="1.0" exclude-result-prefixes="fmp">
<xsl:output method="xml" version="1.0" encoding="windows-1251" indent="yes"/>
<xsl:template match="/">
    <product>
        <product_count>
            <xsl:value-of select="count(//fmp:ROW)"/>
        </product_count>
        <xsl:for-each select="fmp:FMPXMLRESULT/fmp:RESULTSET/fmp:ROW">
            <product_info>
                <description_info>
                    <xsl:value-of select="fmp:COL[1]/fmp:DATA"/>
                </description_info>
                <desc_line_1>

                </desc_line_1>
                <desc_line_2>
                    <xsl:value-of select="fmp:COL[3]/fmp:DATA"/>
                </desc_line_2>
                <short_description>
                    <xsl:value-of select="fmp:COL[4]/fmp:DATA"/>
                </short_description>
                <long_description>
                    <xsl:value-of select="fmp:COL[5]/fmp:DATA"/>
                </long_description>
                <dest_url>
                    <xsl:value-of select="fmp:COL[6]/fmp:DATA"/>
                </dest_url>
                <ean>
                    <xsl:value-of select="fmp:COL[7]/fmp:DATA"/>
                </ean>
                <sku>
                    <xsl:value-of select="fmp:COL[8]/fmp:DATA"/>
                </sku>
                <group_name>
                    <xsl:value-of select="fmp:COL[9]/fmp:DATA"/>
                </group_name>
                <product_name>
                    <xsl:value-of select="fmp:COL[10]/fmp:DATA"/>
                </product_name>
                <stock_level>
                    <xsl:value-of select="fmp:COL[11]/fmp:DATA"/>
                </stock_level>
                <upc>
                    <xsl:value-of select="fmp:COL[12]/fmp:DATA"/>
                </upc>
                <web_link>
                    <xsl:value-of select="fmp:COL[13]/fmp:DATA"/>
                </web_link>
                <position>
                    <xsl:value-of select="fmp:DATA"/>
                </position>
                <images>
                    <xsl:variable name="count" select="count(fmp:COL[14]/fmp:DATA)"/>
                    <image_count>
                        <xsl:value-of select="$count"/>
                    </image_count>
                    <xsl:for-each select="fmp:COL[14]/fmp:DATA[position()&lt;=$count]">
                        <img>
                            <xsl:value-of select="position()"/>
                        </img>
                    </xsl:for-each>
                </images>
            </product_info>
        </xsl:for-each>
    </product>
</xsl:template>

This works except for the bit which gives me the correct number of tags, but no data

    <images>
        <image_count>7</image_count>
        <img/>
        <img/>
        <img/>
        <img/>
        <img/>
        <img/>
        <img/>
    </images>

Anyone able to help be with the last little loop ?

Answer 1

You're making things much more complicated than you need to:

<xsl:for-each select="fmp:COL[14]/fmp:DATA">
  <img>
    <xsl:value-of select="."/>
  </img>
</xsl:for-each>

will give you

As an aside, I've had to write filemaker XSLTs in the past and to keep myself sane (and not have to remember the right column indexes for each field) I've used a trick like this:

<xsl:variable name="mdf" select="/fmp:FMPXMLRESULT/fmp:METADATA/fmp:FIELD" />
<xsl:variable name="descIntro" select="count($mdf[
    following-sibling::fmp:FIELD/@NAME = 'description intro']) + 1" />
<xsl:variable name="descL1" select="count($mdf[
    following-sibling::fmp:FIELD/@NAME = 'Description Line 1']) + 1" />

and so on. This creates a variable for each field name containing the correct index for that field, so you can then use expressions like fmp:COL[$images] instead of fmp:COL[14]. This has the additional advantage that if you later change the export definition to include additional fields the XSLT automatically compensates, you don't have to modify all the numbers by hand.
