xsd2xml

Java-based XML Schema (XSD) to XML instance generator

Introduction

xsd2xml is a Java-based XML Schema document to XML instance generator. Unlike the approach used by JAXB, there is no schema compilation step to generate any code. Instead, xsd2xml uses the Apache XMLSchema library to parse the given schema document and takes the root element for which the XML document must be generated.

xsd2xml originated as a component in the Examine Web Services Testing tool and is used to generate SOAP request message payloads using the XML Schema present in a WSDL 1.1 document

Features

• Generate attributes marked optional
• Generate elements with minOccurs = 0
• Generate the other branches in choice as comments
• Generate comments when processing particles
• Generate repeating elements based on minOccurs/maxOccurs value
• Generate recursive elements upto a configurable depth
• Generate default values for the different XmlSchema types
• Generate compact XML or pretty-printed/formatted XML

Usage

Load the XML Schema file from which to generate XML instances

String path = "..."
InputStream is = this.getClass().getResourceAsStream(path);
URL xsdUrl = this.getClass().getResource(path);

Create an XmlSchemaCollection and XmlSchema instance

XmlSchemaCollection coll = new XmlSchemaCollection();
coll.setBaseUri(xsdUrl.toString());

StreamSource source = new StreamSource(is);
XmlSchema schema = coll.read(source);

Configure the XML generation options

XmlGenOptions options = new XmlGenOptions();
options.setGenCommentsForParticles(true);
options.setGenChoiceOptionsAsComments(false);
options.setMaxRecursiveDepth(1);
options.setMaxRepeatingElements(2);
options.setDefVals(DefaultValues.DEFAULT);

Create an instance of SchemaTypeXmlGenerator

SchemaTypeXmlGenerator generator = new SchemaTypeXmlGenerator(coll, options);

Generate XML by specifying the root element QName

boolean isPretty = true;
String xml = generator.generateXml(elName, isPretty);
