XML conversion not happening correctly

Hi ,

I'm using method create_text in interface IF_IXML_DOCUMENT to convert the SAP data for sales orders into a XML file.

The problem i'm facing is when there are special characters in these texts like & ,<,>,lt etc... it is not converting into correct format.

For eg, if Material type is MAT&1 this method is returning MAT&amp .

similarly for other charaters .

any idea how to resolve it, would be very help full.

any OSS notes that needs to be applied .

Thanks
