Import Long text from XML nodes into NAV

Hi,

I want to import an xml, which has Node data size more than 1024 characters. If I use a variable of type Text (BigText) in the XMLPort and then use CREATEOUTSTREAM to assign this text value to a BLOB field in NAV table, then the format  (white space, next line etc.) of then line gets distorted.

And instead of using Text/Bigtext, if I use the BLOB field in the XMLPort then it gives error

"The length of the text string exceedst the size of the string buffer."

I am using NAV2009 R2.

What are other possibilities? Please help.
