[Gambas-bugtracker] Bug #3013: XML Api does not work correctly

[<bugtracker@xxxxxxxxxxxxxx>]

Charlie REINL reported a new bug.

Summary
-------

XML Api does not work correctly

Type             : Bug
Priority         : Medium
Gambas version   : Master
Product          : XML components


Description
-----------

I have tested XmlDocument and XmlReader from gb.xml.

Both functions have the problem of not recognizing incorrect XMLs 
with getbrokenXMLString
That is the same as getGoodString, but I broke it by hand : <rule> instead of <rules> in leading tag  
you should normaly see an “XML processing error: Mismatching tag. Expected: </rule>.”  message.

XmlReader does not always recognize elements correctly.
In getErrorString, an element with the attribute and its value is output as a combined string.

See getGoodString what the output should look like (but the A-Value  is in getErrorString invalid )
getErrorString 
	Element:= summarystatusinvalid

getGoodString
	Element:= summary
	## summary found 
	Attribute = status
	A-Value = valid

I am posting a demo project. This evaluates XMLs and should 
read out the value of the element:= summary , the value of the attribute = status (Value = valid or invalid)
