Access a map parameter during the XHTML processing

[gbebie-valerian-antidot]

Hello there,
I'm currently struggling to finalize an XHTML plugin which aims at copying othermeta metadata from the map to the topics. To achieve this operation, I rely on a parameter to communicate the input.map.url of the map.

I have already implemented this plugin for HTML5 output, but while trying to use the XHTML transtype, I notice I am not able to retrieve the information from the map.

The plugin is quite simple. Here it is attached:
com.toto.othermeta.xhtml.zip

I've used this declaration in the plugin.xml:

<?xml version="1.0" encoding="UTF-8"?>
<plugin id="com.toto.othermeta.xhtml">
    <feature extension="dita.conductor.xhtml.param" file="buildXhtmlParam.xml"/>
    <feature extension="dita.conductor.xhtml.toc.param" file="buildXhtmlParam.xml"/>
    <feature extension="dita.xsl.xhtml" file="./xsl/get-move-othermeta.xsl"/>
</plugin>

The buildXhtmlParam includes this info:

<params xmlns:if="ant:if">
    <param name="input.map.url" expression="${xhtml.map.url}" if:set="xhtml.map.url"/>
</params>

And after in my xslt I just declare the following verifications:

<xsl:param name="input.map.url" as="xs:string?"/>
<xsl:variable name="mapDoc" as="document-node()?">
    <xsl:apply-templates select="document($input.map.url)" mode="normalize-map"/>
</xsl:variable>
<xsl:template match="/">
    <xsl:message>Value of input.map.url: <xsl:value-of select="$mapDoc"/></xsl:message>
    <xsl:if test="$mapDoc">
        <xsl:message>Document loaded successfully from <xsl:value-of select="document-uri($mapDoc)"/></xsl:message>
        <xsl:message>Number of nodes in the document: <xsl:value-of select="count($mapDoc//*)"/></xsl:message>
    </xsl:if>
    ....

Surprisingly, as explained before, the same plugin worked well for html5. Of course, the definition of the param used to communicate info with the map differed and relied onto another declaration:

<?xml version="1.0" encoding="UTF-8"?>
<params xmlns:if="ant:if">
    <param name="input.map.url" expression="${html5.map.url}" if:set="html5.map.url"/>
</params>

Do you have any idea where the issue lies?
Thanks for any support.

I had a similar problem in the past. This was my way to get it working:

Set your local param like this:

<?xml version="1.0" encoding="UTF-8"?>
<extension>
  <param name="input.map.url" expression="${dita.temp.dir}${file.separator}${user.input.file}"/>
</extension>

In the XSLT you can refer to the file like this to load it:

<xsl:param name="input.map.url" as="xs:string?"/>
<xsl:variable name="escapedFilePath" select="replace($input.map.url, '\\', '/')"/>
<xsl:variable name="replaceSpaces" select="replace($escapedFilePath, ' ', '%20')"/>
<xsl:variable name="concatUri" select="concat('file:/', $replaceSpaces)"/>
<xsl:variable name="strippedUri" select="replace($concatUri, '//', '/')"/>
<xsl:variable name="mapDoc" select="document($strippedUri)"/>

I've updated the plugin here: com.toto.othermeta.xhtml.zip

Thank you so much Pieterjan!
It totally answers to the question.
