Hello,
I do have an element in my input XML file which has a
nested structure with lots of other elements. If the
context element is called <element1>, I need to
process all the child elements of <element1> by
changing the case of their data, leaving two specific
child elements <child1> and <child2>.
Eg:
<someroot>
<element1>
<child1>first child<child1>
<name>
<firstname>John</firstname>
<lastname>Doe</lastname>
</name>
<address>
<street>555 First Stree</street>
<city>some city</city>
<state>some state</state>
<child2>random</child2>
</address>
</element1>
<otherelements/>
</someroot>
So data of all the elements between <element1> tags
should be changed to a different case except the data
in the elements <child1> and <child2>.
Any help would be appreciated.
Thanks.
The example provided is not a well-formed xml document. Also child2 is
not a child of element1.
Below is a solution to your problem, using the following modified
source.xml:
----------
<someroot>
<element1>
<child1>first child</child1>
<name>
<firstname>John</firstname>
<lastname>Doe</lastname>
</name>
<address>
<street>555 First Stree</street>
<city>some city</city>
<state>some state</state>
<child2>random</child2>
</address>
<child2>of element1</child2>
</element1>
<otherelements/>
</someroot>
Transformation:
--------------
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output omit-xml-declaration="yes"/>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="text()[normalize-space()]">
X<xsl:value-of select="."/>
</xsl:template>
<xsl:template
match="text()[ancestor::child1[../self::element1]
or
ancestor::child2[../self::element1]
]">
Y<xsl:value-of select="."/>
</xsl:template>
</xsl:stylesheet>
when applied to the source xml document above, this transformation
produces the following result:
<someroot>
<element1>
<child1>
Yfirst child</child1>
<name>
<firstname>
XJohn</firstname>
<lastname>
XDoe</lastname>
</name>
<address>
<street>
X555 First Stree</street>
<city>
Xsome city</city>
<state>
Xsome state</state>
<child2>
Xrandom</child2>
</address>
<child2>
Yof element1</child2>
</element1>
<otherelements></otherelements>
</someroot>
This is essentially the identity transformation with an override for
text nodes, which have a "child1" or "child2" ancestor, whose parent is
"element1".
In case in the text of your message:
"
I need to
process all the child elements of <element1> by
changing the case of their data, leaving two specific
child elements <child1> and <child2>.
"
you meant not "child elements" but "descendent elements", then the
match of the overriding template should be changed to:
text()[ancestor::child1[ancestor::element1]
or
ancestor::child2[ancestor::element1]
]">
