David CarrigerSubject: XSLT Problem...Is This Even Do-able?
Author: David Carriger

Hi All!

I have beeen researching my problem for quite some time and haven't read any situation where someone else is doing what I need to do...it makes me wonder if anybody has attempted this task.I am working at the request of a client who has (paper-version) troubleshooting flowcharts, whereby logic trees are built on a structure given numerous Tests (rectangle), Malfunctions (diamond) and two answer-values Yes/No (circles) for each Test. The client would like for these flowcharts to be transformed from the XML files into SVG files that on being produced (I am supposing from a Perl/Java batch script), the YES/NO circles become clickable URI's which take the user to the next SVG file based on their selected decision.

I was successful at creating an XSLT which successfully performed the transformation for a 9-page (paper-version) flowchart; however, the client would like to have a one-XSLT-fits-all XML files...transforming each into a long flowing generated SVG which will navigate from every YES/NO to the appropriate new Test.

With the research that I have thus accomplished, I believe this to be an unrealistic task, primarily because each and every flowchart is unique...there are no two alike in any way in their tree structure. If they were all identical, then a template XSLT could be created, I think.

This brings me to my query. I have theorized to my colleagues that if were to break all of these flowcharts into individual elements and make them identical in form, where each work package has 1 Test, 1 Malfunction and 2 Decisions YES or NO, then it might then become possible to accomplish this task.

By breaking my XML source files into smaller packets and experimenting with flowing data into an SVG transformation, I was successful to that end; however, the largest issue that I just can't seem to crack is my XREF for the YES/NO value-answers. I am attempting to surround my YES and NO "<xsl:value-of select="@name"/>" with an <a> and in which the HREF value attribute is streamed from within the XREF element in order to create the appropriate URI for each YES/NO within the SVG's that are created.

Can anybody help? Is this task do-able or am I way off base?

My source files are as follows (for that particular snippet):

<!-- SOURCE: XSLT -->

<xsl:template match="select-value">
<xsl:for-each select="value-answer">
<xsl:if test="position() != last() and (@name='YES' or 'NO')">
<svg xml:space="preserve" width="100%" height="100%">
<text x="218" y="384" style="text-anchor: start; font-size: 8pt;">
<a
xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="<!-- PROBLEM: NEED VALUE-OF "YES" XREF/HREF FROM SOURCE XML STREAMED HERE -->">
<xsl:value-of select="@name"/>
</a>
</text>
</svg>
</xsl:if>

<xsl:if test="position()=last() and (@name='YES' or 'NO')">
<svg xml:space="preserve" width="100%" height="100%">
<text x="79" y="464" style="text-anchor: start; font-size: 8pt;">
<a
xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="<!-- PROBLEM: NEED VALUE-OF "NO" XREF/HREF FROM SOURCE XML STREAMED HERE -->">
<xsl:value-of select="@name"/>
</a>
</text>
</svg>
</xsl:if>
<xsl:apply-templates/>
</xsl:for-each>
</xsl:template>

<!-- SOURCE: XML -->

<select-value id="T00002-TS-11-5820-890-30-105" idtoken="idtokenT00002-TS-11-5820-890-30-105" name=" ">
<indication name="content">
<pcnarr>5 DIGIT PART OF DISPLAY LIT</pcnarr>
</indication>
<value-answer name="YES">
<testblockref>
<xref href="T00003.svg"/>
</testblockref>
</value-answer>
<value-answer name="NO">
<testblockref>
<xref href="T00002.svg"/>
</testblockref>
</value-answer>
</select-value>

You can use Attribute Value Template like that

<a xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="{@name}"></a>

Thanks, Ivan. That got me up-and-running. I could have sworn I had already tried using {}, but obviously not. So, I used your suggestion changing the statement to:

xlink:href="{testblockref/xref/@href}"

...and that did the trick. Thanks for the info.

David
