updating element name and value using XSLT - xslt

Question

In context to my earlier question at "XSLT transformation from XML to XML document". Further i was trying
to rename the "<value>" element to "<sName>" along with updating the value to "ABC" if the value of "dataset/type/text() ='test'". I wrote below code
for the same but it was not working as expected. please help.
Source XML-
<soapenv:Header/>
<soapenv:Body>
<v1:QueryRequest version="1">
<subject>
<dataList>
<!--1 or more repetitions:-->
<dataset>
<type>company</type>
<value>abc</value>
</dataset>
<dataset>
<type>user</type>
<value>xyz</value>
</dataset>
</dataList>
</subject>
<testList>
<!--1 or more repetitions:-->
<criteria>
<type>test</type>
<value>1234</value>
</criteria>
<criteria>
<type>test2</type>
<value>false</value>
</criteria>
</testList>
</v1:QueryRequest>
</soapenv:Body>
</soapenv:Envelope>
XSL file :-

</xsl:choose>
</xsl:template>
<xsl:template match="type/text()">
<xsl:value-of
select="translate(., 'abcdefghijklmnopqrstuvwxyz','ABCDEFGHIJKLMNOPQRSTUVWXYZ')" />
</xsl:template>
</xsl:stylesheet>
Expected Output:
<testList>
<criteria>
<type>test</type>
<sName>ABC</sName>
</criteria>
<criteria>
<type>test2</type>
<value>false</value>
</criteria>
</testList>

Answer 1

Within a
<xsl:template match="criteria[type='service']/value">
the value element is the current context node, so your other XPath expressions need to be relative to that, i.e. instead of
<xsl:when test="criteria[type='service']/value/text()='1234'">
you would just use
<xsl:when test="text()='1234'">
or better
<xsl:when test=".='1234'">
