Help needed transforming XML using multiple XSLT files.

LenovoThinkCentre · August 27th, 2012, 09:36 PM

Hello All,

I’m trying to keep my XSLT files small and maintainable by performing a series of transformations on my XML using multiple XSLT files. My issue is that the last XSLT transformation seems to override the previous XSLT transformation.

In this example, when I attempt to transform the XML using Main.xslt, Chapters.xslt and finally Intro.xslt, the results only show the Intro tags (all book and chapter tags are removed).

Does anyone know where I am going wrong (also, please forgive my - I haven't compiled the example to test it - it is only intended as an example).

Yes, I am new to this.

Something like this:

<book>
<intro>This is an intro to the book</intro>
<chapter>
<content>First chapter text</content>
</chapter>
<chapter>
<content>Second chapter text</content>
</chapter>
<chapter>
<content>Last chapter text</content>
</chapter>
</book>

Main.xslt
<xsl:stylesheet: version=”1.0” xmlns:xsl=”http://www.w3.org/1999/XSL/Transform”>
<xsl:template match=”/”>
<Book>
<Intro/>
<Chapters/>
</Book>
</xsl:template>
</xsl:stylesheet>

Chapters.xslt
<xsl:stylesheet: version=”1.0” xmlns:xsl=”http://www.w3.org/1999/XSL/Transform”>
<xsl:template match=”Chapters”>
<xsl:for-each select=”book/chapter”>
<xsl:value-of select=”content”/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

Intro.xslt
<xsl:stylesheet: version=”1.0” xmlns:xsl=”http://www.w3.org/1999/XSL/Transform”>
<xsl:template match=”Intro”>
<xsl:value-of select=”book/intro”/>
</xsl:template>
</xsl:stylesheet>

You need to add an identity template to each stylesheet, so that elements that aren't matched are copied over unchanged:

Code:

<xsl:template match="*>
  <xsl:copy><xsl:copy-of select="@*"/><xsl:apply-templates/></xsl:copy>
</xsl:template>

Dear Michael,

I can't express how thankful I am for your super-fast and super-awesome help. I did exactly what you said and it fixed all of my issues. My "pipeline" framework is now buzzing and transformations are flying :-)!

I don't know how much time and stress you have saved me, but I'm certain it was huge.

Dear sir, I am in your debt!

Thank you so much!

Lenny.
