I have a string of the form â??abc.def.ghiâ?? (java namespace ) where
â??abc.defâ?? is the package name and â??ghiâ?? is the class name. I need to
extract these two from the complete string : â??abc.def.ghiâ?? -------â??
â??abc.defâ?? + â??ghiâ??
In java this would take about 1-2 lines of code, but in XSLT I cannot
figure out a way to do it without writing tons of code. Why is the
support for string manipulation and regular expressions non-existent
in XSLT, when XML is all about text ( more than java etc.. )??
Iâ??m constantly frustrated by trying to write little templates to do
these simple things like splitting a string etc.
In XSLT 1.0 I do think string handling is a bit awkward, but I
wouldn't have thought it was considered a HUGE amount of code:
<xsl:template name="package">
<xsl:param name="class" /> <!-- name of class (e.g., org.highwire.bar.Baz
-->
<xsl:param name="package" /> <!-- private use -->
<xsl:choose>
<xsl:when test="contains($class , '.')">
<xsl:call-template name="package">
<xsl:with-param name="class" select="substring-after($class, '.')" />
<xsl:with-param name="package" select="concat($package, '.',
substring-before($class, '.'))" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$package" />
<xsl:text>, </xsl:text>
<xsl:value-of select="$class" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
You would, of course, modify the xsl:otherwise to return something in the
form you wanted. I just used a string In XSLT 2.0 it is easier, since we
have regex:
<xsl:template name="package">
<xsl:param name="class" /> <!-- name of class (e.g., org.highwire.bar.Baz
-->
<xsl:analyze-string select="$class" regex="(.+)\.([^\.]+)$">
<xsl:matching-substring>
<xsl:value-of select="regex-group(1)"/>
<xsl:text>, </xsl:text>
<xsl:value-of select="regex-group(2)"/>
</xsl:matching-substring>
</xsl:analyze-string>
</xsl:template>
