XSInstance

You can find command line utility xsd-instance.sh in jlibs/bin directory.

xsd-instance.sh <xsd-file> [root-element]

for example:

xsd-instance.sh purchase-order.xsd {http://jlibs.org}PurchaseOrder

here root-element is optional. If not specified, It will guess root-element
from the given schema. It it finds multiple root elements in schema, then it
prompts to chose one among them.

you can configure various options in jlibs/bin/xsd-instance.properties

minimumElementsGenerated=2

maximumElementsGenerated=4

minimumListItemsGenerated=2

maximumListItemsGenerated=4



# for following properties value can be always/never/random

generateOptionalElements=always

generateOptionalAttributes=always

generateFixedAttributes=always

generateDefaultAttributes=always

---

Programmatic Usage

First you parse the schema file as follows:

import jlibs.xml.xsd.XSParser;

import org.apache.xerces.xs.*;



XSModel xsModel = new XSParser().parse("purchageOrder.xsd");

Create an instanceof XSInstance and configure various options

import jlibs.xml.xsd.XSInstance;



XSInstance xsInstance = new XSInstance();

xsInstance.minimumElementsGenerated = 2;

xsInstance.maximumElementsGenerated = 4;

xsInstance.generateOptionalElements = Boolean.TRUE; // null means random

now genreate the sample xml as follows:

import jlibs.xml.sax.XMLDocument;



QName rootElement = new QName("http://jlibs.org", "PurchaseOrder");

XMLDocument sampleXml = new XMLDocument(new StreamResult(System.out), true, 4, null);

xsInstance.generate(xsModel, rootElement, sampleXml);
