Hmm, this doesn't seem to be exactly what I want, because it would still lack the flexibility of being able to put anything inside a call to a named template, e.g. <call-template name=fontstyling> ... text ... apply-templates ... call to another template ... apply-templates ... </call-template> and simply have whatever was generated be inserted into the template (via a param if necessary). > For now, one approach is that of Mike Kay --- you can check the archive > for details, but the meat of it is this: > <xsl:stylesheet version="1.0" > xmlns:xsl="http://www.w3.org/1999/XSL/Transformorg/1999/XSLhttp://www.w3.org/1999/XSL/Transform"> > > <xsl:template name="xyz" match="xsl:template[@name='xyz']"> > <xsl:message>Hello xyz.</xsl:message> > </xsl:template> > > <xsl:template match="/"> > <xsl:variable name="tname" select="'xyz'"/> < <xsl:apply-templates select="document('')/*/xsl:template[@name=$tname]"/> > </xsl:template> > > </xsl:stylesheet> This has the same problem as I mentioned, unfortunately (besides the yuck factor). > The other approach is to rethink your problems and solutions.

I am definitely open to any solution to the problem, but unfortunately this doesn't work for me since attributes can't get you <B> </B> <I> </I> tags etc, and I can't use CSS since support for older browsers is a must. I am very surprised that there is not a straightforward way to insert stuff into a template like this in XSL, it seems that it is: - computationally trivial - conceptually very simple - simple to represent syntactically - extremely useful After re-reading the spec for the nth time, it appeared as if my idea of using a variable would work (passing an RTF to the template as a parameter), but for some reason, I can't seem to apply templates within the variable. I don't understand why the two generated sections aren't identical in the following: XSL: <xsl:template name="foo"> Template foo was called. </xsl:template> <xsl:template name="fontstyle"> <xsl:param name="param1"/> <B><xsl:copy-of select="$param1"/></B> </xsl:template> <xsl:template match="/"> <xsl:apply-templates select="test1"/> </xsl:template> <xsl:template match="test1"> Output using variable and template to make bold =============================================== <xsl:variable name="var1"> <!-- note that following section is the same as in the section below --> <xsl:call-template name="foo"/> <xsl:value-of select="test2"/> <xsl:apply-templates select="test3"/> test test </xsl:variable> <xsl:call-template name="fontstyle"> <xsl:with-param name="param1" select="$var1"/> </xsl:call-template> Output without using variable and template ========================================== <B> <!-- note that following section is the same as in the section above --> <xsl:call-template name="foo"/> <xsl:value-of select="test2"/> <xsl:apply-templates select="test3"/> test test </B> </xsl:template> <xsl:template match="test3"> <I> <xsl:value-of select="test4"/> </I> </xsl:template> XML: <test1> test1 data <test2> test2 data </test2> <test3> <test4> test4 data </test4> </test3> </test1> RESULT: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> Output using variable and template to make bold =============================================== <B> Template foo was called. test2 data </B> Output without using variable and template ========================================== <B> Template foo was called. test2 data <I> test4 data </I> </B> Any clarifications on how the rtf for a variable is generated (and restrictions on the use of that variable) would be very much appreciated, this has got me baffled. Or, any suggestions on how to achieve what I want via other means (CSS is not an option, though) would be great too! Thanks again, Iain. //----------------------------------------------------
