Using XML for string message

[Deepti Bhatia]

Hi,

We have to design our application to communicate to other java system with string messages. Could you guide if we can use XML to validate the message length , indivisual parameters rather than having string comparision coded for huge message.

XML is a string. There should be no restriction that stops you from passing XML there.

Ok...and what about the XML tags. When the XML is formed they are part of it.The string message that we have would be something like eg : FULLNAME length 10, FirstName length 7.

Request message - FULLNAME00DRAGO00. something like. How do we get this from an XML. Am very new to XML can you guide.

Why cant you use xsd schema? It can define the max and min length of element text and attribute. Or you can possibly use DTD.
And the most "stupid" variant. Every time you pass the XML you can add "rule" tags, for example:

...
< root>
   < rules>
      < rule/>
         < rule-name > firstname-maxlen </ rule-name>
         < rule-value> 10 < /rule-value>
      < /rule>
   < /rules>
   < values>
      < value-name> firstname < /value-name>
      < value-data > 0123456789 < /value-data>
   < /values>
< /root>
...
