Hi Mark, At 04:18 PM 5/10/00 +0100, you wrote: >so firstly, can someone give me a minimal script that will take a file of >XML and replicate it unchanged as output. i guess you need a template to >override each default rule for how each input element is handled (including >comments, processing instructions etc.) Not quite: you can override all default rules together. An identity transform is given in the XSL spec, section 7.5: <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> >secondly, can you modify this to show a test for the presence of a named >child element which inserts it if it is not present Rather than modify it, supplement it with a template specifically for that element where you want the test and possible new child: <xsl:template match="yourelement"> <xsl:copy> <xsl:apply-templates select="@*"/> <xsl:if test="not(child)"> <child><!-- whatever you like --></child> </xsl:if> <xsl:apply-templates select="node()"/> </xsl:copy> </xsl:template> >and finally, can you modify this to show testing the presence of an >attribute and inserting a default if it is not present <xsl:template match="yourelement"> <xsl:copy> <xsl:if test="not(@yourattribute)"> <xsl:attribute name="yourattribute"> <xsl:text>yourdefaultvalue</xsl:text> </xsl:attribute> </xsl:if> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> Note that I haven't tested this stuff, but I think it'll do what you want.
