by ADMIN 48 views

Introduction

Validating XML files against XSD-1.1 schemas is a crucial step in ensuring data integrity and consistency. In this article, we will explore the use of a command line tool for validating XML files with XSD-1.1 schemas on Ubuntu. We will discuss the requirements, installation process, and usage of the tool.

Requirements

To validate XML files with XSD-1.1 schemas, you will need the following:

  • Ubuntu: The tool is designed to work on Ubuntu, but it may also work on other Linux distributions.

  • Java: The tool requires Java to be installed on your system. You can install Java on Ubuntu using the following command:

sudo apt-get update sudo apt-get install default-jdk


*   **libxerces2-java**: This library is required for XSD-1.1 validation. You can install it using the following command:

```bash



sudo apt-get update
sudo apt-get install libxerces2-java

Free and Open Source XSD 1.1 Validation Tool

After installing the required libraries, you can use the following command line tool for XSD-1.1 validation:

  • Xerces: Xerces is a free and open source XSD 1.1 validation tool. You can use the following command to validate an XML file against an XSD-1.1 schema:

java -jar xerces.jar -v -n -s xsd_file.xsd -i xml_file.xml


    Replace `xsd_file.xsd` with the path to your XSD-1.1 schema file and `xml_file.xml` with the path to your XML file.

The `-v` option enables verbose mode, which displays detailed information about the validation process. The `-n` option enables non-interactive mode, which suppresses the display of the Xerces logo.

The `-s` option specifies the XSD-1.1 schema file to use for validation. The `-i` option specifies the XML file to validate.

If the XML file is valid, Xerces will display a success message. If the XML file is invalid, Xerces will display an error message indicating the reason for the failure.



Alternative Tools


If you encounter issues with Xerces, you can try using alternative tools for XSD-1.1 validation. Some popular alternatives include:


    

  • 

    Saxon: Saxon is a free and open source XSD 1.1 validation tool that supports a wide range of features, including XSD 1.1, XSLT 3.0, and XPath 3.0. You can use the following command to validate an XML file against an XSD-1.1 schema:
    

    

    • 



java -jar saxon.jar -v -n -s xsd_file.xsd -i xml_file.xml


Replace `xsd_file.xsd` with the path to your XSD-1.1 schema file and `xml_file.xml` with the path to your XML file.

The `-v` option enables verbose mode, which displays detailed information about the validation process. The `-n` option enables non-interactive mode, which suppresses the display of the S logo.

The `-s` option specifies the XSD-1.1 schema file to use for validation. The `-i` option specifies the XML file to validate.

If the XML file is valid, Saxon will display a success message. If the XML file is invalid, Saxon will display an error message indicating the reason for the failure.
