Hi All,

I have a XML file which i want to search an element with two set of values in the PCDATA.
The element is CustomNoteTypeName and can have two values i.e. DBHA or DAKO.
If these two values are found then change the root element of the XML file to something other what is at present if not found let the XML files process the way are to be.

Kindly let me know if you need more information from my end.

Thanks

Karan

Let me suggest libxml's xmllint. Hope you have time to write DTD for XML you expect so that parser/validator is able to clean up.
Apache may ship some better tools in java, I am not big fan of.

libxml2 download here, do not compile.

xmllint is not supported by my client's AIX machine. I cannot add anything on top of the server.

All i am looking for is a simple awk which does the job. I have tried the below but its not helping me somehow:-

{
  if ( index($0, "<NumberType>ZAP</NumberType>") )
   {
                  gsub(/XmlInterchange/,"XmlInterchange_new",$0);
          print $0;
   }
  else
   {
                print $0;
}

Linux affinity components can be installed and uninstalled at will and are somewhat supported by IBM. An tou may install libxml2/xmllint on windows (or use one already present on Linux wg via vmware or virtualbox)to see whether it helps. If you post example of source and fixed XML I might get luckier with awk/sed/perl.

Is it just as simple as replacing one string with another?

sed s/'>WWW<'/'>XXX<'/g

?

I think your not getting my point...I need to check for a specific element and the value inside a XML and then replace the root element.

Then you have to use XML parser like apache xerces (Java) or libxml.
AIX has not even got Unicode capable sed/awk/grep, that basically makes it unable to parse XML.
