Merge Two XSL Files-CodePudding

I've inherited some XSL that I'm struggling with.

The docs say that XSL is supposed to find the body then:

Replace any designated strong or em sections of text
Find and replace <2029> and <2028> strings with line returns

It would seem that only one or the other of the above functions in the XSL I inherited work at a time. Either I get the strong/em formatting, or the line returns are fixed, depending on how I modify the XSL.

Is there a way to get BOTH applied?

CodePudding user response：

I think if you have two separate transformations to perform on the same elements, the best way is often to run a pipeline of two transformations controlled by separate stylesheets.

It's sometimes more convenient to do the two transformations within a single stylesheet using something like

<xsl:variable name="output-of-phase-1">
  <xsl:apply-templates mode="phase-1"/>
</xsl:variable>
<xsl:apply-templates select="$output-of-phase-1" mode="phase-2"/>

CodePudding user response：

There are so many problems in this "inherited" stylesheet that I don't know where to start. Just a couple of notes on things that I see.

There are three different templates for matching the root document node.

First:

  <xsl:template match="/">
    <xsl:apply-templates select="//as:story[@name='body']"/>
  </xsl:template>

Then:

  <xsl:template match="/">
          <xsl:value-of select="//as:story[@name='body']"/>
  </xsl:template>

Finally:

  <xsl:template match="/">
          <xsl:value-of select="$fp2028"/>
  </xsl:template>

Since these three templates match an identical item (the root document-node) and they have no priorities assigned, only this third template matching "/" will be selected. That's what's giving the current output in this inherited worksheet.

According to your description and to your desired output, you want to also execute at least these two templates:

  <xsl:template match="as:run[@i]">
    <xsl:text>&lt;em&gt;</xsl:text><xsl:value-of select="."/><xsl:text>&lt;/em&gt;</xsl:text>
  </xsl:template>

  <xsl:template match="as:run[@b]">
    <xsl:text> &lt;strong&gt;</xsl:text><xsl:value-of select="."/><xsl:text>&lt;/strong&gt; </xsl:text>
  </xsl:template>

However, your current worksheet will never execute these templates because they are never applied from this third template matching the root document.

I've tried to apply the sound principles that Dr. Kay has described above by performing successive operations from your worksheet on intermediate variables. I've commented out some of the dead code but haven't removed it entirely. I believe that this is closer to your expected output, although not identical.
