xslt - XML to XML transform based on attribute value of previous sibling and ancestor to parent -


note: edited make elements , attribute values visible (they invisible before because used angle brackets) , provide complete sample xml source file.

i'm trying create xsl complex xml xml transform.

i have xml has text elements <a:t> have various paths start either /p:sld or /p:notes end /p:csld/p:sptree/p:sp/p:txbody/a:p/a:r/a:t.

these <a:t> elements need transformed different target xml elements based on how path starts , attribute value of (sometimes present) preceding sibling <a:ppr> <a:r> in turn parent <a:t>.

here's minimal version of of source xml example: http://pastie.org/9559309

here xpaths of various <a:t> elements , target xml them. edit: added new item @ start of items paths start /p:notes

  • xpath /p:sld/p:csld/p:sptree/p:sp/p:txbody/a:p/a:r/a:t <body>
  • xpath /p:sld/p:csld/p:sptree/p:sp/p:txbody/a:p/a:r/a:t (<a:r> tag preceded <a:ppr lvl="1">) <bulleted>
  • xpath /p:sld/p:csld/p:sptree/p:sp/p:txbody/a:p/a:r/a:t (<a:r> tag preceded <a:ppr lvl="2">) <bulleted2>
  • xpath /p:notes/p:csld/p:sptree/p:sp/p:txbody/a:p/a:r/a:t <body>
  • xpath /p:notes/p:csld/p:sptree/p:sp/p:txbody/a:p/a:r/a:t (<a:r> tag preceded sibling <a:ppr lvl="1"> ) <body>
  • xpath /p:notes/p:csld/p:sptree/p:sp/p:txbody/a:p/a:r/a:t (<a:r> tag preceded sibling <a:ppr lvl="2"> ) <bulleted>
  • xpath /p:notes/p:csld/p:sptree/p:sp/p:txbody/a:p/a:r/a:t (<a:r> tag preceded sibling <a:ppr lvl="3"> ) <bulleted2>

note how it's interaction of start of path , attribute value of <a:ppr> when <a:ppr> present determines xml element output. example:

element <a:t> parent <a:r> preceded <a:ppr "lvl=1"> should produce <bulleted> if source xpath starts /p:sld if source path starts /p:notes <a:t> tag else same should <body> in output.

finally, need transform couple of elements near root xpath /p:notes <pagebreak> , xpath /p:sld <pagebreak>.

the output xml should this. edit: matches content of source xml.

<document> <pagebreak></pagebreak> <bodytext>activity 1:</bodytext> <bodytext>services platform</bodytext> <bodytext>objective :</bodytext> <bulleted>the objective of activity identify services each node supports</bulleted> <bodytext>description :</bodytext> <bulleted>this individual activity. using information covered , drawing on next page fill in table information requested instructor</bulleted> <bodytext>ig: mandatory individual activity. time: 5 – 10 min.</bodytext> <pagebreak></pagebreak>  <bodytext>2</bodytext> <bodytext>activity 1: </bodytext> <bodytext>services platform</bodytext> <bodytext>to complete activity, use following material:</bodytext> <bulleted>the drawing , table on next page, along information provided instructor.</bulleted> </document>

<pagebreak> empty element, <bodytext> , <bullet> elements contain text relevant <a:t> in source xml, other elements source xml stripped.

update: i've written xsl seems should work take contents of each a:t element in input xml , put appropriate output element name around on output. body changed bodytext don't issues body being reserved html word. 

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform" xmlns:fo="http://www.w3.org/1999/xsl/format" xmlns:xs="http://www.w3.org/2001/xmlschema" xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main" xmlns:r="http://schemas.openxmlformats.org/officedocument/2006/relationships" xmlns:p="http://schemas.openxmlformats.org/presentationml/2006/main"> <xsl:template match="/">     <xsl:for-each select="//a:t/">         <xsl:choose>             <xsl:when test="(count(ancestor::p:sld) > 0) , (count(ancestor::a:r[preceding-sibling[1]@lvl='1']) > 0">                 <bulleted><xsl:value-of select="."/></bulleted>             </xsl:when>             <xsl:when test="(count(ancestor::p:sld) > 0) , (count(ancestor::a:r[preceding-sibling[1]@lvl='2']) > 0">                 <bulleted2><xsl:value-of select="."/></bulleted2>             </xsl:when>                      <xsl:when test="(count(ancestor::p:notes) > 0) , (count(ancestor::a:r[preceding-sibling[1]@lvl='2']) > 0">                 <bulleted><xsl:value-of select="."/></bulleted>             </xsl:when>             <xsl:when test="(count(ancestor::p:notes) > 0) , (count(ancestor::a:r[preceding-sibling[1]@lvl='3']) > 0">                 <bulleted><xsl:value-of select="."/></bulleted>             </xsl:when>     <xsl:otherwise>                 <bodytext><xsl:value-of select="."/></bodytext>     </xsl:otherwise> </xsl:choose> </xsl:for-each>     </xsl:template> </xsl:stylesheet>

i'm getting syntax errors transform related fact a:t uses prefix i'm not sure how fix errors.

i'm not sure how tell transform xsl processor put pagebreak on output each p.sld or p.notes element appears on input , have show @ proper place. seems should maybe make outer "for-each /document/p.sld or /document/p.notes" command

  • outputs <pagebreak></pagebreak> tag pair
  • then starts inside for-each a:t in code above, limited scope of p.sld or p.notes element selected outside for-each
  • then closes outside for-each command sending processor next p.sld or p.notes in source xml.

thanks can provide.
