insert lines of it_final into table it_final1.

delete it_final1 where finaltext = space.

endloop.

In the above code you can observe 2 methods:

1.value = attr->get_value( ).

2.value = node->get_value( ).

So in the second method the actual data is comind and storing in variable 'value' which is declared as type string.

So when i exicute it is retrieving only 132 characters into value.

This method get_value is in inerface 'IF_IXML_NODE'

Can any body provide some solution for this.
