Hi!
We are trying to migrate from MRM to XMLNCS. In the MRM domain, the name of the root element of the input message isn't stated explicitly so I can refer to the content of the XML message (its elements) directly
| Code: |
| InputRoot.MRM.header.field1 |
regardless of the name of the root element.
Is the simple way in XMLNSC domain to do the same? I mean to obtain a general way to rewrite from InputRoot to OutputRoot elements of the message which are of the same form, as was previously coded:
| Code: |
| OutputRoot.MRM.header.field1 = InputRoot.MRM.header.field1 |
Regards,
Pawel

Have you tried:
| Code: |
| OutputRoot.XMLNSC.header.field1 = InputRoot.XMLNSC.header.field1 |

So if the input document looks like
| Code: |
<xml>
<root>
<header>
<field1>data</field1>
<field2>data</field2>
<header/>
<body>
<field1>data</field1>
....
</body>
</root> |
Then, yes, when you import the schema that describes this into an MRM model, then you will use
to access the field1 data from the header, and use will use
| Code: |
| Root.root.header.field1 |
to access the field1 data from the header.
And, yes, it's easy enough to use find/replace to change all occurrances of "Root.header" to "Root.root.header". |

Yes, but in such case I have to know the name of the root element ("root" in this case). I ask if I can do this in situation when I don't know what I've got on input, but I know that the message on input contains "header".

Start here and keep reading.

Thanx.
I did this like this:
| Quote: |
OutputRoot.XMLNSC.outbody.header.field1 = InputRoot.XMLNSC.(XML.Element)[1].header.field1 |

You might want to consider using a field type different to XML.Element. Something that starts with XMLNSC which is part of the XMLNSC domain would be my tip.

pawel_janowski: Not sure whether
a) you're a genius or
b) the XMLNSC pages in the info center are getting quite good or
c) you had a lucky moment
Either way, that is exactly the right solution. |

It will be more performant to
| Code: |
Declare thisRef REFERENCE TO InputRoot.XMLNSC;
MOVE thisRef FIRSTCHILD FIELDTYPE(XMLNSC.Element) |
Note that you cannot safely use XML domain constants when referring to XMLNSC elements. |

Except for that pesky "(XML.Element)" stuck in there. |

| mqjeff : Good point. That *must* be changed to XMLNSC.Element. I'm sure pawel_janowski knows why this is important. |

I followed your tip and used XMLNSC.Folder instead of XML.Element.
Thanks.

XMLNSC.Element is the correct choice.
If your document consisted of a single root tag with a value, XMLSNC.Folder wouldn't match the root element. I know that's an unlikely input document, but XMLNSC.Element is specifically designed for matching any XML tag. Accurate code is better than code that 'just works'. |
