Hi
Is anyone knows how to parse '&' to the target xml. It is an hardcoded value at the compute node and the incoming parser is XMLNSC.
Ex:
Source attribute: <name id='&en' />
Expected target attribute: <name id='&en' />
Actual target attribute: <name id='&en' />
How to avoid append this 'amp' text to '&'.
Any advice would be appreciated. |

Don't worry. &en is illegal XML. The correct XML value is <name id='&en' />
When extracted from the XML it will automatically revert to &en.
& is one of those values that HAVE to be escaped in XML.
| Code: |
SET ref.name.(XMLNSC.attr)id='&en';
-- will result in <name id='&en' /> |
Have fun

Thanks for the reply fjb_saper.
My target is fileOutput node.
Below is the line in the compute node.
SET OutputRoot.XMLNSC.name.(XMLNSC.Attribute)ID = '&en';
Outcome :
<name ID="&amp;en;" />
Issue still exists. |

Read fjb_saper's answer again (carefully).
In your code, Broker will convert the first & to the legal escape sequence & and then add the string literal amp;en as indeed you have found.

| When the XMLNS parser generates a bit stream from a message tree, occurrences of ampersand (&), less than (<), greater than (>), double quotation mark ("), and apostrophe ('), within the attribute value, are replaced by the predefined XML entities &, <, >, ", and '. |

Use the following line instead:
SET OutputRoot.XMLNSC.name.(XMLNSC.Attribute)ID = '&en';

Have you tested jsware the above line of code? |

Not specifically - have you? What happens?

Looking again at what you want:
<name ID='&en'>
This is invalid XML as fjb_saber mentioned. So are you asking how you can produce an invalid XML document containing an unmarked-up ampersand?
What I suggested will produce:
<name ID='&en'>
which is the XMLNSC parser working correctly.
If you are expecting '&en' to be an XML entity (like &) then &en is slightly incorrect. All XML entities are in the form '&name;' - beginning with ampersand and ending with semicolon. &en is not a valid entity name format - just like & is incorrect too - its &
To create inline DTD's that define custom XML entities, see http://pic.dhe.ibm.com/infocenter/wmbhelp/v9r0m0/topic/com.ibm.etools.mft.doc/ac67190_.htm for details.
If you are expecting the XMLNSC parser which, by design, produces well formed XML, to produce bad XML then that is going to be a bit more difficult.
