[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Processing Recursive Groups
 I'm trying to process groups within groups. Basically, if an XSD element refers to a group with <xsd:group ref="X"/> , I would like to expand this to include the actual group (rather than a reference to it). Im able to do this without any problem, however, there's a snag (as always). I have some group declarations that contain references to itself. My basic script obviously will give a stack overflow as it keeps substituting the same group over and over again. <xsd:group name="X"> ... <xsd:group ref="X"/> <!-- KEEPS SUBSTITUTING = NO GOOD! --> </xsd:group> So my script starts off like this: <xsl:key name="allGroups" match="xsd:group[string(@name)]" use="@name"/> When it comes time to process group references within elements I have something like this to take care of the recursion: ... <xsl:for-each select="xsd:group"> <xsl:if test="string(@ref)"> <xsl:choose> <xsl:when test="not[ancestor::xsd:group[@name=current()/@ref]]"> <xsl:for-each select="key('allGroups',string(@ref))"> <xsl:apply-templates select="*"/> </xsl:for-each> </xsl:when> <xsl:otherwise> <xsl:element name="group"> <xsl:attribute name="ref"> <xsl:value-of select="@ref"/> </xsl:attribute> </xsl:element> </xsl:otherwise> </xsl:choose> </xsl:if> </xsl:for-each> .... BUT, this doesn't work. I'm pretty sure the "when" statement isn't doing it's job properly. For example, if you come across a group reference in an element: <xsd:element name="blah"> <xsd:group ref="X"/> </xsd:element> And a group defined with a reference to itself: <xsd:group name="X">
<xsd:element name="a">
<xsd:group ref="X"/>
</xsd:element>
<xsd:group ref="Y/>
</xsd:group><xsd:group name="Y"> <xsd:element name="b"/> </xsd:group> The end result should look like: <element name="blah">
<element name="a">
<group ref="X"/>
</element>
<element name="b"/>
</element>Shouldn't my script substitute group X in the element, and not substitute itself when it sees that its ancestor is itself, and continue substituting group Y (in group X) ?? I hope this makes sense. If there is a technique out there that can take care of this then I can aslo apply that technique to complexTypes that define elements refering to the same complexType. Thanks for any help. Greatly appreciate it! Wasiq Shaikh _________________________________________________________________ Windows Live Hotmail is the next generation of MSN Hotmail.
