So I kind of got it working but need some help, I'll first post xml,

1. XML

              </details>

        </ret>
</ns2:getMessages>
</body>


2. xsl

<?xml version="1.0"?>

      </ret>

    </xsl:otherwise>
   </xsl:choose>
  </xsl:otherwise>

 </xsl:element>
</xsl:template>
</xsl:stylesheet>

3. output

<?xml version="1.0" encoding="UTF-8"?>

<State>1</State>
<details>
<Error>
<Problem>Its pending</Problem>
</Error>
</details>

Questions:

1. But now I don't get <ret> and <Msg> tags, Msg tag in one xml could
be Msg and other it could <CMsg> rest of the tags are same. How can I
get them.
2. Also I am losing the indentation, it's all appearing on first
column. I did get rid of ns2 though.
3. In above xsl what do I have to do if I want to make sure that it's
the element node "State" whose child text node is "PENDING"?

Also am I doing this xsl transformation correctly, in the sense that
do you see any problems in terms of how it's done, efficiency etc.

Thanks for your help.

When you apply-templates to the ret element it does apply-templates on the
Msg element, which does xsl:copy-of the Msg element. It does not not do an
apply-templates on the State element so the code that replaces "PENDING"
with "1" is never activated.

In your match="/" template, the only apply-templates is to

an element

called "ret". There is no element named ret in your source

document.

Therefore the template rule with match="*" will never fire,

therefore

the code that replaces "PENDING" by "1" will not be executed.

So I tried various things but it doesn't seem to be working.
I'll give the complete information:

1. xml file:
<?xml version="1.0" encoding="UTF-8"?> <Msg
xmlns:ns2="http://www.abc.com/wsdl/v";>
<Msg>
               <cid>103850015_0_1219420995471</cid>

               <State>PENDING</State>
            </Msg>
</Msg>

2. xsl file:

<?xml version="1.0"?>
<xsl:stylesheet

exclude-result-prefixes="xmlns:ns2 ns2 xmlns"> <xsl:output

          <xsl:copy-of select="//ret/*" />
       </ret>
    </xsl:when>
    <xsl:when test="not($file2//State='PENDING')
                and not($file2//State='SUCCEDED')">
       <ret>
          <xsl:copy-of select="$file2//ret/*" />
       </ret>
    </xsl:when>
    <xsl:otherwise>
          <xsl:apply-templates select="//ret"/>
    </xsl:otherwise>
  </xsl:choose>

   <xsl:otherwise>

               <State>PENDING</State>
            </Msg>
</Msg>

4.expected output:

<?xml version="1.0" encoding="UTF-8"?> <Msg>
               <cid>103850015_0_1219420995471</cid>

               <State>1</State>
            </Msg>
</Msg>


First I don't understand how there are 2 Msg nodes. And
second I wasn't able to get rid of namespace node by using
<element> as suggested by Michael, it's still copying the
namespace node.

1. So would above template mentioned by Mukul also output

node HIJ ?


I think, "outputting the node" is not the correct

terminology. We can

copy the node to the result tree, or write something else to the
result tree, derived from the properties of the input nodes.


      <xsl:when test="local-name()="HIJ" and . = 'YYYYYY'">


This statement will probably not compile, as I can see some

misplaced quotes.




3. Currently I am using XSLT 1.0 and I am using JAXP which

uses Xalan.

How do I start using XSLT 2.0.


You need to download an XSLT 2.0 processor, like Saxon and

using it as

described in the documentation.


Would it just be matter of upping version in stylesheet node?


No. version="2.0" is just a hint to the processor. You need

to supply

the XSLT 2.0 stylesheet to a XSLT 2.0 processor like Saxon.
