Hi , wondering if anyone noticed this issue, we upgraded brokr to 7.0.0.5 recently and after that it dosent seem to be parsing XML, even though the debugger shows the XML tree.
In more detail, at the start of the compute node, I am copying OutputRoot=InputRoot and when provided a well-formed XML as input (that opens in IE), If I check if OutputRoot.XMLNSC IS NOT NULL or InputRoot.XMLNSC IS NOT NULL, the checks fail...
anyone see this strange behaviour? |

If you suspect something like this, the obvious next steps are:
1. Insert a Trace node after the input node
2. Take a debug-level user trace and read it carefully.
The most likely reason for this that you have specified Parse Timing as 'On demand' on the input node, and your message flow logic is not triggering any parsing at all. This is as-designed. |

| looks like the issue is that my incoming xml has namespace specified. how do i handle namespaces in broker. Do i need to model the message? |

What exactly are these checks supposed to be checking for?
InputRoot.XMLNSC and OutputRoot.XMLNSC are typically NAME elements that won't have a value, so "IS NOT NULL" would return FALSE, whether the elements exist or not, and whether the elements have child elements or not.

What happens exactly, when the "incoming xml has namespace specified"? What problem does this cause? The XMLNSC parser should be able to handle XML messages with namespaces, with or without an associated schema. |

Same way you handle any other XML artififact.

Not need, but you must at least account for the namespaces.
I agree with my associate; what are you trying to do? Whatever it is, that code probably won't do it.

you may want to use browse to these sections from the infocenter corresponding to your broker version. Not that the way you work with namespaces will change between versions.
1. Developing message flow applications > Transforming messages > Using ESQL > Writing ESQL > Manipulating messages in the XML domains > Manipulating messages in the XMLNSC domain > The message body
2. Developing message flow applications > Transforming messages > Using ESQL > Writing ESQL > Manipulating messages in the XML domains > Working with XML messages

| I am just trying to do simple operations such as existence of a tag or value of a certain tag in XML. What i see is that it works fine in the case of XML inout messages that dint have a namespace defined in the opening tag - i.e xmlns=... but fails when the message has a namespace defined.. |

so for example, if I have :
| Quote: |
<StartTag xmlns="urn:iso:std:iso:20022:tech:xsd:setr" xmlns:t="http://www.w3.org/namespace/">
<Tag1>34566775</Tag1>
<Tag2>123456</Tag2>
</StartTag>
|
How do i check for existence or values of Tag1 and Tag2? |

| Code: |
IF EXISTS(InputRoot.XMLNSC.*:StartTag.*:Tag1) THEN
...
END IF
|
I'm wildcarding the namespace above but you can reference particular ones if you want (look it up in the infocenter). |

Put in those Trace nodes, as suggested in my last post.
Read the topics - they really do contain useful information.
Post again when you have done both of those things. |
