Subject: Getting a flat mapping of XSLT fields for documentation purposes...
Hi,
I'm trying to put together an XSLT which will take an arbitrary XSLT (that maps
data from one XSD schema to another XSD schema), and provides (on a best-effort
basis) a flat view of the mapping from the point of view of the XSD being
mapped to.
i.e.
If I've got 3 files:
1)XSDInput.xsd - defines input data format
2)XSDOutput.xsd - defines output data format
and
3)XSLTmapper.xslt - maps from input data format (XSDInput.xsd) to
output data format (XSDOutput.xsd)
I want to create a generic XSLT file:
- -> XSLTFlatMappingForDoco.xslt
that takes various
XSLTMapper.xslt
files, and produces something like:
<Maps>
<Map>
<from>s1:StreetName</from>
<to>s0:Pda_Inf_Street_Name</to>
</Map>
<Map>
<from>s1:StreetType</from>
<to>s0:Pda_Inf_Street_Type</to>
</Map>
<Map>
<from>s1:StreetSuffix1</from>
<from>s1:StreetSuffix2</from>
<to>s0:Pda_Inf_Street_Suffix</to>
</Map>
....
</Maps>
which says that field
s0:Pda_Inf_Street_Name
comes from:
s2:StreetName
and
<from>s1:StreetSuffix1</from>
<from>s1:StreetSuffix2</from>
<to>s0:Pda_Inf_Street_Suffix</to>
s0:Pda_Inf_Street_Suffix
comes from:
s1:StreetSuffix1
s1:StreetSuffix2
etc.
Any other additional info would be a bonus, but I'm not too fussed about that
right now...bigger problems trying to do just the above!
I've got this so far...
<?xml version='1.0' ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:s0="URN:AU.GOV.NSW.POLICE.XML.SERVICE.APPLICATION.COPSEVENT.CAD400NWS.VERSION_1_0_0">
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:template match="*">
<Maps>
<xsl:for-each select="descendant-or-self::xsl:value-of">
<Map>
<from>
<xsl:value-of
select="../../parent::xsl:for-each/@select"/>
</from>
<to>
<xsl:value-of select="name(../.)"/>
</to>
</Map>
</xsl:for-each>
</Maps>
</xsl:template>
</xsl:stylesheet>
which sort of does a liiiiitle bit of the job (completely useless at this
point...).
Has anyone done this sort of thing before, or know how to approach it?
I'm completely lost for how to do it using XSLT. I don't want to have to resort
to code. I suspect that'll be even uglier.
Thanks
Cheers
