If you need to run an XPath query over the documents in the current collection, just click on the "Query" button and the XPath query dialog will popup.

Its hard to think of a particular case in a B2B scenario where you would define a service that accepts any type of XML document, but for testing purposes we have found it very useful to have a generic Service that accepts any document, and does some very simple processing. xCommerce has a special XML Template called {System} {ANY} designed to accept any XML document as Input or Output. So if you define the input for a Service or Component using {System} {ANY} the issue becomes how do you map its structure/content which you don't know and could be anything at runtime?

I'm trying to port some Xalan code to Resin and wanted to know how to do the following:

This tutorial introduces XPath and covers most aspects of it. It is aimed at people who do not know XPath or want a refresher. If you plan to use XSLT, you should take this tutorial first. You will learn: What XPath is, the syntax and semantics of the XPath language, how to use XPath location paths, how to use XPath expressions, how to use XPath functions, and how XPath relates to XSLT. XPath is a W3C standard. This tutorial covers version 1.0.

The Jaxen project is a Java XPath Engine. Jaxen is a universal object model walker, capable of evaluating XPath expressions across multiple models. Currently supported are dom4j and JDOM.

The XPath and XPathSearch plugin allow you to search your blog using XPath queries. The XPath plugin differs from the XPathSearch plugin in that a different URL parameter is used for the XPathSearch plugin.

This document is an informal guide to the syntax of XPath expressions, which are used in SAXON both within XSLT stylesheets, and in the Java API. For formal specifications, see the XSLT and XPath standards, except where differences are noted here.

There are several good open source XPath engines for Java, most distributed as part of XSLT processors.

This article describes how to best optimize XPath queries when you execute these queries against annotated XSD schemas.

XSLT and XPath are gaining a reputation for helping Open Source and commercial developers tie into web and web services applications.

XPath is a language for addressing parts of an XML document, used most commonly by XSLT. There are various APIs for processing XPath. For the purposes of this article I will use the open source Jaxen API. Jaxen is a Java XPath engine that supports many XML parsing APIs, such as SAX, DOM4J, and DOM. It also supports namespaces, variables, and functions.

This document describes how to use Saxon as a Java class library, without making any use of XSLT stylesheets. If you want to know how to control stylesheet processing from a Java application, see using-xsl.html.

Generates an XML directory listing performing XPath queries on XML files. It can be used both as a plain DirectoryGenerator or, by specifying a parameter xpath, it will perform an XPath query on every XML resource.

An Introduction to XPath

This article demonstrates how to query an XPathDocument object with an XML Path Language (XPath) expression using the XPathNavigator class. XPath is used programmatically to evaluate expressions and select specific nodes in a document.

Some emails and comments on Screenscraping HTML with TagSoup and XPath alerted me to the fact that the example I gave on that page has gone out of sync with the current release of JDOM and no longer works. I've reworked the example using Xalan 2.5.

The Saxon API only works with Saxon. The Xalan API only works with Xalan. Both only work with Java.

This article is based on the assumption that the reader is familiar with the configuration for SQL Server 2000's virtual root and associated virtual names for templates and schema.

An XPath query operates on a namespace well-formed XML document after it has been parsed into a tree structure. The particular tree model XPath uses divides each XML document into seven kinds of nodes:

This paper presents the METAXPath data model and query language. METAXPath extends XPath with support for XML metadata. XPath is a specification language for locations in an XML document. It serves as the basis for XML query languages like XSLT and the XML Query Algebra.
