Subject: [xsl] getting result documents out of a function that calls transform() From: "Graydon graydon@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> Date: Wed, 31 Mar 2021 18:25:07 -0000 |
In the interest of doing a bunch of small named transformations in a particular order (for refactoring, or to regularize content before processing it generally), I have this function: <xsl:function name="local:processList" as="document-node()"> <xsl:param as="document-node()" name="initial" /> <xsl:param as="xs:string*" name="list" /> <xsl:choose> <xsl:when test="not(exists($list))"> <xsl:sequence select="$initial" /> </xsl:when> <xsl:otherwise> <xsl:sequence select=" local:processList( transform( map:merge(($transformMap(head($list)), map:entry('source-node', $initial)) ) )?output, tail($list) )" /> </xsl:otherwise> </xsl:choose> </xsl:function> The function works fine; given an initial document, a list of named transformation events, and a map between transformation even names and maps of transform() paramters: <xsl:map> <xsl:map-entry key="'first'"> <xsl:map> <xsl:map-entry key="'stylesheet-location'" select="'one.xsl'" /> <xsl:map-entry key="'stylesheet-params'"> <xsl:map> <xsl:map-entry key="QName('', 'debugPath')" select="concat($diagnosticPath, '/first.xml')" /> </xsl:map> </xsl:map-entry> <xsl:map-entry key="'static-params'"> <xsl:map> <xsl:map-entry key="QName('', 'DEBUG')" select="$DEBUG" /> </xsl:map> </xsl:map-entry> </xsl:map> </xsl:map-entry> b& </xsl:map> (and the actual individual transform xsl documents), it does the thing and performs each of the transforms in the expected order. I can get $DEBUG into the transform function call, so in principle xsl:result-document is being called when $DEBUG is true to return whatever document the individual XSL transform produced. How do I get those DEBUG result documents back out of the function? The only approach I can think of is to add an argument to the function and have that accumulate the full return maps from calls to transform() and to pass that back when the function completes. This feels like it lacks elegance. Is there a better way? Thanks! -- Graydon Saunders | graydonish@xxxxxxxxx CC&s oferC)ode, C0isses swC! mC&g. -- Deor ("That passed, so may this.")
