Example usage for org.apache.commons.jxpath JXPathContext createPathAndSetValue

Introduction

In this page you can find the example usage for org.apache.commons.jxpath JXPathContext createPathAndSetValue.

Prototype

public abstract Pointer createPathAndSetValue(String xpath, Object value);

Source Link

Document

The same as setValue, except it creates intermediate elements of the path by invoking an AbstractFactory , which should first be installed on the context by calling #setFactory .

Usage

From source file:org.apache.cocoon.components.source.impl.XModuleSource.java

public void notify(Document insertDoc) throws SAXException {

    // handle xpaths, we are only handling inserts, i.e. if there is no
    // attribute of the given name and type the operation will fail
    if (!(this.xPath.length() == 0 || this.xPath.equals("/"))) {

        Object value = getInputAttribute(this.attributeType, this.attributeName);
        if (value == null)
            throw new SAXException(" The attribute: " + this.attributeName + " is empty");

        JXPathContext context = JXPathContext.newContext(value);

        if (value instanceof Document) {
            // If the attribute contains a dom document we
            // create the elements in the given xpath if
            // necesary, import the input document and put it
            // in the place described by the xpath.
            Document doc = (Document) value;

            Node importedNode = doc.importNode(insertDoc.getDocumentElement(), true);

            context.setLenient(true);/*  w w  w .j av  a  2  s.c o m*/
            context.setFactory(new DOMFactory());
            context.createPathAndSetValue(this.xPath, importedNode);
        } else {
            // Otherwise just try to put a the input document in
            // the place pointed to by the xpath
            context.setValue(this.xPath, insertDoc);
        }

    } else {
        setOutputAttribute(this.attributeType, this.attributeName, insertDoc);
