RE: [xsl] need help with converting attribute into elements

["Michael Kay" <mhk@xxxxxxxxx>]

The following solution (using a few 2.0 features) is perhaps a little
more elegant.

<xsl:template match="text">
<xsl:apply-templates select="." mode="inline"/>
</xsl:template>

<xsl:template match="*[@bold='true']" mode="inline" priority="10">
<b><xsl:sequence select="my:inline(., @bold)"/></b>
</xsl:template>

<xsl:template match="*[@italic='true']" mode="inline" priority="9">
<i><xsl:sequence select="my:inline(., @italic)"/></i>
</xsl:template>

<xsl:template match="*[@underline='true']" mode="inline" priority="8">
<u><xsl:sequence select="my:inline(., @underline)"/></u>
</xsl:template>

<xsl:template match="*" mode="inline" priority="7">
<xsl:apply-templates/>
</xsl:template>

<xsl:function name="my:inline" as="element()">
  <xsl:param name="elem" as="element()"/>
  <xsl:param name="att" as="attribute()"/>
  <xsl:variable name="x">
    <xsl:copy>
    <xsl:copy-of select="$elem/(node() | @*) except $att"/>
    </xsl:copy>
  </xsl:variable>
  <xsl:apply-templates select="$x" mode="inline"/>
</xsl:function>
