Hi,
Is it possible to create a tag like <tag>AB \n CD</tag> , where \n is a newline ?
Not sure how the target system would interpret that but I am trying to know if such a thing is even possible in ESQL..
Pls reply.
thanks.

You'd need to include the \n as markup, in the same way if you need a < in an XML tag you'd need to mark it up as <.
There's a list of valid markup in the W3C XML standards doc.

You can add a newline to any ESQL value by enclosing a newline in single-quotes.
Or you can cast the appropriate hex values to characters, and use that.
Vitor - newlines are not significant in XML, there's no entity for it.

No, you're right, they're not. You have to include them as hex values (&#A) if they're included.

In element content, it's perfectly fine to use plain newlines (whatever one considers to be a plain newline).
One may or may not reasonably expect them to be preserved as such, however.
In element names, one should a) not use newlines, b) not expect them to be preserved.

In ESQL you should be able to use something like:
| Code: |
| set OutputRoot.XML.MyElement = '<'; |
And it gets marked up into:
| Code: |
| <MyElement><</MyElement> |
for you.
Lets not start the debate about XML being deprecated - pleeasse
