Chandra, you might want to look through the XSLT FAQ at http://www.dpawson.co.uk/. This along with some of the books suggested at the site can help a lot. But to answer your questions: > When u say <xsl:apply-templates select="NAME"/>, Will all the > NAME nodes > under MEMBER be selected(say there are more than 1 NAME nodes under > MEMBER)? yes (but only NAME children, not descendants that are an lower in the hierarchy) >Also will the NAME template rule be applied to each > one of the NAME > nodes before the Phone node is selected? yes > > 2) > <xsl:variable name='signers' > select=/legal_authenticator/person'/> > <xsl:if test='$signers'> > ..... > ..... > </xsl:if> > > What is the xsl:if tag doing here? Is it testing whether > /legal_authenticator/person' exists?? yes > > 3)<person_name> > <nm> > <GIV V="Henry"/> > <FAM V="Levin"/> > </nm> > <person_name.type_cd V="L" S="2d"/> > </person_name> > > For the above xml, I see the following in the stylesheet > <xsl:apply-templates > select='person_name[person_name.type_cd/@V="L"]'/> > What do the [] mean?? Why can't I just have / instead of the []?? [] is what the XSLT spec calls a predicate. It's a way of specifying a criteria rather than pointing to a specific node. So, what this select is saying (in English) is: Select all person_name nodes from the current context that contain a person_name.type_cd element with a V attribute whose value is "L" But what is selected is the person_name node and that's what the XSLT engine looks for and how it selects the template to apply to person_name. If you had this instead: <xsl:apply-templates select='person_name/person_name.type_cd/@V="L"/> what the select would say would be: Select the V attribute on the person_name.type_cd element that is a child of a person_name element that is a child of the current context. It selects the attribute. Sara XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
