My perl script reads messgaes from this queue, and drops them to
another queue after creating a backup in a text file. My requirement
is I have check the value of a particular tag for example, value of
<FIELD>, if that is say "FINANCE GROUP", I have to change it to
"FINANCIAL SYSTEMS" and then drop to the other queue. I tried below,
but for some reason it did not work. COuld you please help.
This is a design issue. There is a specification mismatch and someone
has made a decision to make things even worse.
If your source is XML and bound to stay that way then the proper way to
do things is to apply an XSLT transform to all <FINANCE GROUP> elements.
You cannot do this properly in Perl because you cannot predict the
contents of the element you are required to transform, and copying it
verbatim is unlikely to succeed.
IMO your senior needs a slap. Just make sure that, if you write a simple
global
s/<(\/?)FINANCE_GROUP>/<$1FINANCIAL_SYSTEMS>/g
you expect it to go wrong. That is not XML.
