Transforming XSLT

[callado4]

I have created some XSLT stylesheets to convert some XML into an XSL-FO document. I now have a requirement to move any font or font-size attributes for fo:blocks into a child fo:inline element.

So say I have something like this:

<fo:block font-size="6pt">
This font is 6 points
</fo:block>
<fo:block font="8px Arial">
This font is Arial 8 points
</fo:block>
<fo:block>Just text</fo:block>
<fo:block>
<fo:external-graphic src="graphic.gif"/>
</fo:block>

I would like to create an xslt stylesheet to transform it to:

<fo:block>
<fo:inline font-size="6pt">
This font is 6 points
</fo:inline>
</fo:block>
<fo:block>
<fo:inline font="8px Arial">
This font is Arial 8 points
</fo:inline>
</fo:block>
<fo:block>Just text</fo:block>
<fo:block>
<fo:external-graphic src="graphic.gif"/>
</fo:block>

You can construct the xsl document like this : importing an identity transformation and then adding the specific template, shown below, for the purpose.
[tt]
<xsl:template match="fo:block">
<xsl:copy>
<xsl:if test="@font-size|@font">
<fo:inline>
<xsl:if test="@font-size">
<xsl:attribute name="font-size">
<xsl:value-of select="@font-size" />
</xsl:attribute>
</xsl:if>
<xsl:if test="@font">
<xsl:attribute name="font">
<xsl:value-of select="@font" />
</xsl:attribute>
</xsl:if>
<xsl:apply-templates select="node()|text()|comment()|processing-instruction()" />
</fo:inline>
</xsl:if>
<xsl:if test="not(@font-size|@font)">
<xsl:apply-templates select="node()|text()|comment()|processing-instruction()" />
</xsl:if>
<xsl:apply-templates select="@*[(name()!='font-size') or (name()!='font')]" />
</xsl:copy>
</xsl:template>
[/tt]

Slightly simplified:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="[URL unfurl="true"]http://www.w3.org/1999/XSL/Transform"[/URL] xmlns:fo="[URL unfurl="true"]http://www.w3.org/1999/XSL/Format">[/URL]
  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>
  <xsl:template match="fo:block[@font-size|@font]">
    <xsl:copy>
      <fo:inline>
        <xsl:for-each select="@*">
          <xsl:attribute name="{name(.)}"><xsl:value-of select="."/></xsl:attribute>
        </xsl:for-each>
        <xsl:apply-templates/>
      </fo:inline>
    </xsl:copy>
  </xsl:template>
</xsl:stylesheet>
