Hi,
I'm trying to develop a flow that generates an xml message,
wraps it with a header xml but transforms the original xml message to encoded form with entity references.
I'll explain:
Let's say I have the following xml message:
| Code: |
| <message>123</message> |
I want to generate the following message:
| Code: |
<GeneratedMessage><message>123</message></GeneratedMessage>
|
Is there are an elegant way to do this?
I thought about using some java code ...
I'd appreciate any kind of help!

It could be that using CDATA is the way to go here.
Could you explain why you want the original message encoded in that way?

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

| How about using ABITSTEAM and converting that XML message into a bitstream and then setting your envelope xml element's value to that bitstream ? |

sridhsri : That will not escape the XML markup characters, and it is not a good solution anyway. You should only use XML.AsisElementContent or XML.Bitstream when there is no other solution.
Let's wait until alechko states his requirement. |

First of all, thank you all for your quick replies.
This requirement is due to the fact that the xml message might contain xml characters such as "<" and ">".
I agree that the best way to do so is using CDATA but ...
not all clients receiving and sending these message can generate or parse CDATA section.
Surprisingly enough, I found out the using ASBITSTREAM and afterwards "CREATE PARSE ..." as sridhsri suggested generated the whole string with "<" and ">".
Am I just plain lucky or is it the way it is supposed to work? Any other suggestions?
Thanks again,
Alik |

It is designed behaviour, and required by the XML spec. The parser will automatically escape any XML markup characters which appear within the value of an element ( unless the element type is CDataSection ). Otherwise it might generate badly-formed XML documents.
If your inner message is in the form of a message tree, then ASBITSTREAM is the correct way to convert it to a string. I presume the CREATE...PARSE was just your method of checking that you had achieved your goals - not part of the solution. |
