Mark LimSubject: How to create an XSD for flat files with fixed-width records and multiple record layouts
Author: Mark Lim

Hi,

I am evaluating Stylus Studio and am trying to create an XSD for text files that have positional records as well as multiple record layouts in one file. Each record is 1000 Bytes or so and is terminated by CRLF. All records share the first 100 Bytes or so, and the record type (name) is defined at position 95-98 (and not at the beginning of the line).

The text file structure is basically a combination of:
http://www.stylusstudio.com/text_file_to_xml.html and
http://www.stylusstudio.com/varying_record_layout.html

How would I define such an XSD in Stylus Studio?

Our target is to convert these inhouse text files to EDIFACT and ANSI X.12, and vice-versa.

Thanks
Mark

Hi Mark,

Once you have built the template using the Convert to XML module run the the conversion on one of your input files, save the resulting XML on disk then run the XML to XML Schema Document Wizard.

File -> Document Wizard -> XML to XML Schema

For your mapping target, create the appropriate XML Schema using the EDI to XSD document wizard.

Given your source and target, you can create a mapping using either XSLT or XQuery.

Does it help?

Hi Ivan,

"Once you have built the template..."

Do you mean "File | New | Convert to XML"? This is already where I get stuck. The example in http://www.stylusstudio.com/varying_record_layout.html mentions in step 3 to define a separator. But I cannot specify a separator because I am processing a fixed-width text file. But I also cannot use the fixed-width approach in http://www.stylusstudio.com/text_file_to_xml.html because the records in the file are not homogenous.

Our inhouse file looks pretty much like a SAP Idoc (it is a COBOL file, though) but where the segment/record name is not at the beginning of a line but always in columns 95-98.

Thanks
Mark

Have you consider using regular expressions to match the lines?

If you post a sample here we can try to get you started

Hope this helps
