Issue with simple transformation code

Hi Folks

I am working on developing a custom simple transformation, the requirement is convert the upload the file(unknown columns text file) into xml code.

here columns text has not been mentioned so while uploading this data using "upload" function module we can get into string table, so now I want to pass this data into transformation to convert into below format, can you please suggest me how can I do this.

<Template1>

<Name>first 10 characters in the file line1</Name>

<Address>character 11 to 40 in the file line1</Address>

<Salar>character 41 to 50 in the file line1</Salary>

.

.

.

Etc.,

</Template1>

Please suggest me how to split the file line 1 data based on my tags in the simple transformation.

Appreciate your help on this.

Regards,

Naresh.
