Xref text resolution on elements without title

[NicoAMP]

Hi,

In DITA if you use an xref without text, that's the title of linked element that it gets in output (PDF,WebHelp).

For example with following code I will have "Go to How To Make." :

Code: Select all

Go to <xref href="a001" format="dita"/>.

...

<task id="a001">

    <title>How To Make</title>

...

But here I will have "Go to."

Code: Select all

Go to <xref href="a001" format="dita"/>.

...

<stepsection id="ONE-ONE">My stepsection</stepsection>

...

I would like to manage this last case (linked element without title).

For PDF, in my plugin, I just have to insert this template (it works) :

Code: Select all

<xsl:template match="*[contains(@class, ' task/stepsection ')]" mode="retrieveReferenceTitle">

<xsl:value-of select="."/>    

</xsl:template>

But for HTML I don't know where I have to do modification.
I try to modify this template, but inside it it seems that xref text are already resolved:

Code: Select all

<xsl:template match="*[contains(@class, ' topic/xref ')]" name="topic.xref">...

Any idea where xref text for WebHelp (HTML5) are resolved?

Thanks.

Hi Nico,

I think the link texts are resolved for the HTML output in the same XSLT stylesheet in which I advised you here to make changes:

post51896.html

Maybe you can add some xsl:messages in this template:

Code: Select all

<xsl:template match="*[dita-ot:is-link(.)]">

There is an XSLT extension point called "dita.xsl.topicpull" which may allow you to contribute a DITA OT plugin with a custom XSLT stylesheet to override that:

I add a test on text() content on the following template (in topicpullImpl.xsl) and it works.

Code: Select all

<xsl:template match="*" mode="topicpull:resolvelinktext" priority="-1">

        <xsl:variable name="target-text"> 

            <xsl:choose>

                <xsl:when test="*[contains(@class,' topic/title ')][1]">

                    <xsl:apply-templates

                        select="*[contains(@class,' topic/title ')][1]" mode="text-only"/>

                </xsl:when>

                <!--If there isn't a title ,then process with spectitle -->

                <xsl:when test="@spectitle">

                    <xsl:value-of select="@spectitle"/>

                </xsl:when>

                <!--If there is text ,then process text -->

                <xsl:when test="text()">

                    <xsl:value-of select="text()"/>

                </xsl:when>

                <!-- No title, no text or spectitle; check to see if the element provides generated text -->

                <xsl:otherwise>

                    <xsl:apply-templates select="." mode="topicpull:get_generated_text"/>

                </xsl:otherwise>

            </xsl:choose>

        </xsl:variable>

        <xsl:if test="exists($target-text)">

            <xsl:value-of select="normalize-space($target-text)"/>

        </xsl:if>    

    </xsl:template>

Thanks Radu for your help.
