Hi Sharon,
Thanks for the inputs , actually i am using xml as i am trying to take
inputs from a GUI , i take the input then write to the xml , then parse this
xml to get the values into the stax job.
Also i tried your inputs it parses and gets the value properly. Thanks.
I tried to parse the string machine_name which is returned after parsing the
xml file
MyXml.xml .
In <script>
[name, machine_name] = STAXResult
</script>
array_machine = machine_name.split(',')
and get them into array_machine[0] ..[1] [2] etc
inorder to get the individual ip adresses , but i am getting error using
this method of parsing .
Is there any other method to do so .I know this is not a STAX question ,
but it will save me time if i get some pointers.
Regards
Sangram
