Description
I guess that a XML element can either contain another element or a single text node. I’m not sure that the actual implementation respects this logic. It is likely that the actual implementation allows several text nodes within a given element, or even a mix of text nodes and other nodes. This should be checked and the required constraints should be implemented.
Recurrence
No recurrence.

The following code
produces the following XML document
Two observations:
xml = gammalib.GXml()
level1 = xml.append('element type="Measurement"')
level2 = level1.append('parameter name="Flux" value="1.0"')
level3 = level2.append(gammalib.GXmlText("This is a text"))
dump = level2.append(gammalib.GXmlText("This is another text"))
dump = level2.append(gammalib.GXmlText("This is a third text"))
level4 = level3.append(gammalib.GXmlText("This is a nested text"))
level4 = level4.append(gammalib.GXmlText("This is a nested text"))
produces the following XML document
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<element type="Measurement">
<parameter name="Flux" value="1.0">
This is a text
This is another text
This is a third text
</parameter>
</element>
Two observations:
- appending subsequent text nodes to a given XML element adds text fields to the element; they are represented in memory by multiple
GXmlTextobjects; this was maybe not intended but does not really present a problem - appending a text node to a text node does nothing; it’s like the appended text node got lost; this is not a nice feature; probably an exception should be thrown.

I added some code to GXmlNode that throws an exception if an attempt is made to append anything to a text node. This now leads to
Traceback (most recent call last):
File "./test_xml.py", line 90, in <module>
xml = test1()
File "./test_xml.py", line 47, in test1
level4 = level3.append(gammalib.GXmlText("This is a nested text"))
File "/usr/local/gamma/lib/python2.6/site-packages/gammalib/xml.py", line 330, in append
return _xml.GXmlNode_append(self, *args)
RuntimeError: *** ERROR in GXmlNode::append(GXmlNode&): Invalid value.
Invalid attempt to append a XML node to a text node (GXmlText). Nothing can be appended to a text node.
for the above code, hence an exception for
level4 = level3.append(gammalib.GXmlText("This is a nested text"))

Forbid now also to append to comment and processing instruction node. I think I got now all the issues.
