HI All,
I am working on XML2my model transformation. I had XML model and i used AM3 to get the XMI file from XML meta model and i am currently writing the transformation from XML to my model. The injection and stuff worked very well so as the rest of the transformation. However, something weird happened, i can not get the name which is my main part of the transformation. The name is an attribute in the target meta model where as in the source i find it Element which its value is represented in the Text child as it is shown in the part of my xml file written below:
--Example of source model
<children xsi:type="Element" startLine="10511" startColumn="5" endLine="10524" endColumn="20" name="Class1">

As you can see from the above file i have many attributes in target model which are elements in the source model. Now to explain it a little more, the above two in bold font are an example. I started working with them.
---------------------------HELPER
helper context XML!Element def: getSimpleStringDataValue() : String =
let eltC : Sequence(XML!Text) =
self.children->select(d | d.oclIsTypeOf(XML!Text))->asSequence()
in
if eltC->notEmpty()
then
eltC->first().value
else
''
endif;
-----------------Rule for the name
rule transform1
{
from input: XML!Element(input.name = 'Class1')
to output: TargetMM!Class1( name <- Sequence{i.getChildrenByName('nam')->collect(e | thisModule.resolveTemp(e, 'tps'))},
info <- Sequence{i.getChildrenByName('inf')->collect(e | thisModule.resolveTemp(e, 'tps'))},
............ )
}
rule Name{
from in:XML!Text(in.name = 'Name')
using {
textValues : String = inp.getSimpleStringDataValue();}
to nam:TargetMM!Name
(
name <- in.getOptIntAttrValue('Name')
)
)
}
This does not work correctly, and it is so annoying. After all i have done, i am stuck here 
Please look at it and see what is my problem.
Thanks a lot
