Hi,
Im new to this forum but i can see lot of good posts in this site. I have a question about XML.Element.
I did read some posts in this forum on XMLNSC.Element but that didnt help me.
I have a complete logic of sequential xml processing written by traversing an XML with MOVE cursor NEXTSIBLING TYPE XML.Element and MOVE cursor FIRSTCHILD TYPE XML.Element.
Now we are moving this logic to XMLNSC parser. So when i tried replacing XML.Element in move statement with XMLNSC.Element, it doesnt seem to work.
I did get some info about XMLNSC.Folder and XMLNSC.Field but thats not helping me here.
In XML parser, we had XML.Element that we could have used to identify any kind of element but here in XMLNSC, there is no such thing. I have to toggle between XMLNSC.Folder and XMLNSC.Field and that makes my sequential logic complicated.
Also if I dont use any TYPE, then my MOVE statement will traverse through all the attributes and thus i lose time in processing.
Is there any effective way of using XMLNSC.Field and Folder to process elements sequentially or is there any specific way to replace XML.Element in my current code with XMLNSC ??
Thanks,
C* |

Kimbert,
The below code does not give me any error
| Code: |
MOVE cursor FIRSTCHILD TYPE XML.Element;
|
But the below code which i try as a replacement to the above code (as we are moving to XMLNSC parsert) is giving issues - Identifier XMLNSC.Element cannot be resolved.
| Code: |
MOVE cursor FIRSTCHILD NAMESPACE * TYPE XMLNSC.Element;
|
What can be the best replaced for the XML.Element in the above MOVE statement ?
Thanks,
C* |

I presume you are getting the error when you deploy the message flow - but you haven't said so, and you have only quoted a fraction of the message.
You're probably on a version of the runtime which does not support XMLNSC.Element. I think it was added in runtime fixpack 6.1.0.4 or 6.1.0.5. |

Kimbert,
Someone suggested me like this
| Code: |
| MOVE cursor FIRSTCHILD NAMESPACE * TYPE (XMLNSC.Folder OR XMLNSC.Field); |
Is this the right way, because an element can be of two types either folder or field.
On the version, I think its 6.1 but i have dropped a mail to my admin asking for details.
Thanks,

v6.1.0.3 does not support XMLNSC.Element - the simplest solution ( to this problem, anyway ) would be to upgrade to the latest fixpack.
The code snippet which you posted will not work. There is a way to do what you require, but it's not quite as easy as that. If you can't upgrade then I'll find the solution for you. |

Kimbert,
Yes unfortunately we cannot upgrade. Can you please share the other solution ? This is urgent, appreciate your help.
Another suggestion that came around from one of my friends is using
| Code: |
MOVE cursor FIRSTCHILD TYPE 0x01000000;
|
I havent tested this though.
Thanks,
C* |

You will not be able to do this with a TYPE clause on your MOVE statement. Instead, you will need to iterate over the nodes that you are searching and check for XMLNSC.Folder or XMLNSC.PCDataField.
I think this will work, but I haven't tested it:
| Code: |
SET fieldType = FIELDTYPE(ref) BITOR 0x01000000;
IF fieldType = 0x01000000 THEN
-- do stuff
ELSE
move ref to next sibling and try again
|
Don't forget to check LASTMOVE after every MOVE... |

Thanks Kimbert. I did it in this way
MOVE cursor FIRSTCHILD TYPE XMLNSC.Folder;
IF LASTMOVE(cursor) = FALSE THEN
MOVE cursor FIRSTCHILD TYPE XMLNSC.Field;
END IF;
It seems to work so far...

I'd still do a second check on that lastmove(cursor)...
What happens when you are already at the bottom of the tree??

fjp_saper,
This condition is inside a loop and if my lastmove fails then i exit. So if its the last then we just exit processing. So far i havent seen any processing errors and the logic seems to be working but need to check on all use cases.
Thanks,
