Because of merging, we were given a large number of mqsi 21 esqls from another location. We do not have to migrate them to WMB 7 which is our environment. However we like to reuse some of them. Since we started with WMB6, we already use namespace and XMLNSC. We do not have any experience with this. We know that we have to add namespace declaration and name space prefix to the ESQL code in general. Is using an editor to do a massive serach and replace the only way to do it ?
For example FIND OutputRoot.XML.A.B.C REPLACE InputRoot.XMLNSC.ns:A.ns:B.ns:C where ns is the name space prefix.
Any experience you can share will be greatly appreciated. |

I might tend to use a find/replace thingy, like grep or perl or sed or etc, rather than using manual changes in a full featured editor.
But you're still going to have to load the ESQL files into a 7.0 toolkit project and validate them. 2.1 esql has a number of subtle differences that are going to require manual intervention. |

When dealing with namespaces, we have found that local declarations are more convenient rather than global declarations, especially when multiple developers are working in the same area. Therefore, as you are migrating your files, move your namespace decls into the module and out of the global scope. I'm sure others may have differing opinions on this advice. We also standardized the naming convention so that the same XML tag equates to the same namespace tag in all locations.
For future, we want a neat little utility that imports a set of namespaces in all esql files. IMHO. Thanks Vitor.

Search and replace (probably "within files") is fine in my view...
Just to put up an alternative:
You can do that with a texteditor, e.g. notepad++ (or ultraedit) or ...
For XML: Use XMLSpy or oXygen, since I have the impression that they can handle large (and probably also a lot of) (XML-)files better (than a plain texteditor)... but, o.k. you want to convert your ESQLs.
BTW: It is called XMLNSC, but you do not need to use namespaces with the XMLNSC parser!

You should be able to alter your source management systems so that it runs a script when an .esql file is checked out.
which will work like magic until it

I suppose we can use this as a work around until WMB v9. ESQL <import> like the Java <import> would be ideal.

You can currently have a common "imported" esql that contains namespace definitions.
Not exactly the same as an import, but another workaround until WMBv9.

And think also about another alternative:
Write a utility function that will assign the given namespace to each of the children... Start at the top. Find where the namespace changes and reassign the changed one going down... Use REFERENCES.
Make it recursive.
Build once reuse multiple times. Quick way of solving your problem with minimal code changes (thinking of a default namespace here).
You could also insert an added benefit by checking the type and transforming certain XML types to XMLNSC types...
Have fun
