Hi Ssupun,
Is this a better way as per coding standards.
Or, the methodology I have been using is more effective.
In broader terms ,
Sample xml
----------
<operation>
<in1>1</in1>
<in2>2</in2>
</operation>
I will first need to get the parent element, and then all the children and loop
thru it.
axiom_element_get_child_elements creates a list. And what does
axiom_child_element_iterator_has_next do ?
Keeping the above mentioned xml, if you can tell me in a few lines of code,
which will prevent me from running into the "Segmentation issue", it would be
great.
Thanks
Ramesh.
