Hi bix,
Just use the Muenchian method.
This transformation:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:key name="kEl" match="element" use="@name"/>
<xsl:key name="kAttr" match="attribute"
use="concat(../@name, '|', @name)"/>
<xsl:key name="kchEl" match="element"
use="concat(../@name, '|', @name)"/>
<xsl:template match="/">
<els>
<xsl:for-each
select="//element[generate-id()
=
generate-id(key('kEl', @name)[1])
]">
<element name="{(_at_)name}">
<xsl:for-each
select="//attribute[generate-id()
=
generate-id(key('kAttr',
concat(current()/@name,
'|',
@name
)
)[1]
)
]">
<attribute name="{(_at_)name}"/>
</xsl:for-each>
<xsl:for-each
select="//element[generate-id()
=
generate-id(key('kchEl',
concat(current()/@name,
'|',
@name
)
)[1]
)
]">
<elementRef name="{(_at_)name}"/>
</xsl:for-each>
</element>
</xsl:for-each>
</els>
</xsl:template>
</xsl:stylesheet>
when applied on your source.xml:
<els>
<element name="a">
<attribute name="attA1"/>
<attribute name="attA2"/>
<element name="aa">
<attribute name="attAA1"/>
<attribute name="attAA2"/>
</element>
</element>
<element name="b" />
<element name="a">
<attribute name="attA3"/>
<attribute name="attA4"/>
<element name="ab">
<attribute name="attAB1"/>
<attribute name="attAB2"/>
<element name="aba">
<attribute name="attABA1"/>
<attribute name="attABA2"/>
<attribute name="attABA3"/>
<attribute name="attABA4"/>
</element>
</element>
</element>
<element name="a"/>
<element name="b">
<element name="ba"/></element>
</els>
Produces the wanted result:
<els>
<element name="a">
<attribute name="attA1"/>
<attribute name="attA2"/>
<attribute name="attA3"/>
<attribute name="attA4"/>
<elementRef name="aa"/>
<elementRef name="ab"/>
</element>
<element name="aa">
<attribute name="attAA1"/>
<attribute name="attAA2"/>
</element>
<element name="b">
<elementRef name="ba"/>
</element>
<element name="ab">
<attribute name="attAB1"/>
<attribute name="attAB2"/>
<elementRef name="aba"/>
</element>
<element name="aba">
<attribute name="attABA1"/>
<attribute name="attABA2"/>
<attribute name="attABA3"/>
<attribute name="attABA4"/>
</element>
<element name="ba"/>
</els>

All,
I believe this may have been covered before with some of the grouping
q/a's
but I did a few searches both on the fact and the archive, and I was
unable
to find what I was looking for.
Essentially, I've got something similar to the following:
~~~~xml fragment~~~~
<element name="a">
<attribute name="attA1"/>
<attribute name="attA2"/>
<element name="aa">
<attribute name="attAA1"/>
<attribute name="attAA2"/>
</element>
</element>
<element name="b" />
<element name="a">
<attribute name="attA3"/>
<attribute name="attA4"/>
<element name="ab">
<attribute name="attAB1"/>
<attribute name="attAB2"/>
<element name="aba">
<attribute name="attABA1"/>
<attribute name="attABA2"/>
<attribute name="attABA3"/>
<attribute name="attABA4"/>
</element>
</element>
</element>
<element name="a"/>
<element name="b">
<element name="ba"/>
</element>
I would like to combine all of the similar elements and reference the
element children into something like this:
~~~ xml fragment output ~~~
<element name="a">
<attribute name="attA1"/>
<attribute name="attA2"/>
<attribute name="attA3"/>
<attribute name="attA4"/>
<elementRef name="aa"/>
<elementRef name="ab"/>
</element>
<element name="b">
<elementRef name="ba"/>
</element>
<element name="aa">
<attribute name="attAA1"/>
<attribute name="attAA2"/>
</element>
<element name="ab">
<attribute name="attAB1"/>
<attribute name="attAB2"/>
<elementRef name="aba">
</element>
....etc
I am attempting to come up with an automated way of storing off what the
DTD
is of the xml data produced by my database. My hope is that I can
transform
my original xml into this newer format (element/attribute), and then
transform that into a DTD file. I have an xsl file that works through all
of the original xml data and produces what you see above. However, I'm at
a
loss how to group/concatenate the multiple data outputs. If there is a
better way to do this, I'd sure appreciate the help.
Thanks!
bix
