# XMLTRANS Workflow Application

## Overview

The **XMLTRANS** workflow application transforms any XML document to any kind of other format using an XSLT sheet.

## How it works

The WorkflowGen engine calls the XMLTRANS application with the context and the parameters. XMLTRANS uses the context and the parameters to get the following:

* An XML file to convert<br>
* An XSLT file to convert the XML file to any kind of output<br>
* A `RESULT` parameter to receive the output<br>
* A `RESULT_FILEEXT` parameter to know the extension of the output<br>
* A `RESULT_MIMETYPE` parameter to know the MIME type of the output

After XMLTRANS gathers this information, it’s ready to make the transformation, and then returns the context to WorkflowGen so that the workflow can continue.

## Possible execution errors

The following errors can occur during the execution of the transactions:

| Code | Description                                                                                              |
| ---: | -------------------------------------------------------------------------------------------------------- |
|  `1` | The `XML` required field is missing                                                                      |
|  `2` | The `RESULT` required field is missing                                                                   |
|  `3` | The `XSLT` required field is missing                                                                     |
|  `4` | The XML file is not a valid XML document                                                                 |
|  `5` | The XSLT file was not found                                                                              |

|  `7` | Cannot write the output to the `RESULT` parameter. Verify that the folder security settings are correct. |
|  `8` | Cannot read the XML file. Verify that the folder security settings are correct.                          |
|  `9` | The XSLT file is not a valid XSLT transformation style sheet                                             |
| `10` | The received context was not valid                                                                       |
| `11` | If `RESULT_FILEEXT` or `RESULT_MIMETYPE` is given, the other one must be given too                       |
