[OpenSIPS-Users] Use of colon in XML element names

[Vlad Patrascu]

Hi xaled,

There should be no problem with colons in element names (libxml will 
produce some errors, because namespaces are not handled by the xml 
module and the prefix is simply considered as part of the element name, 
but they can be ignored), your issue seems to be caused by something 
else. What errors or other relevant messages do the logs produce? I do 
spot on the other hand a wrong access to the first element when adding 
the attribute, which should look like 
"$xml(xml_s/tns:messageType.attr/xmlns:tns)" but the document should 
still be created fine without that attribute.

As for adding the encoding, you could initialize the $xml variable 
directly with the required XML declaration, like this:

     $xml(xml_s) = '<?xml version="1.0" 
encoding="UTF-8"?><tns:messageType></tns:messageType>';

Formatted output is not possible currently, you can open a feature 
request on Github regarding this, but if you really need the XML 
document to actually contain the indentation characters, you could do so 
explicitly when inserting the nodes (as in the documentation example).
