faassen seems to be in the driving seat. Apparently XPath code works fine with parsedXML. All that needs to happen is a read-only DOM-2 adapter for most zope objects which I believe he is working on.

Calvin Yu presents a simple trick for easily doing assertions on large object graphs in JUnit.

Finding a node is useful but often you will want to select all nodes matching a pattern. For example, a web spider will want to select all links in a HTML page.

The hardest working actors in Hollywood are not the ones whose names are splashed on theater marquees and headlines in People week after week. These folks may make the big bucks, but their popularity can be short-lived. One day they're the toast of the town, the next they're doing Hollywood Squares. No, the real workhorses in Tinseltown are the supporting actors. Take Donald Sutherland: over the course of a fifty-year career, Sutherland has appeared in more than 130 movies, playing heroes, villains, and everything in between. The quantity and versatility of his roles are extraordinary compared to what most leading players get to do in their careers.

Within Flash 2004 you can do simple XPath searches with the use of the XPathAPI class. It has two methods: selectNodeList and selectSingleNode.

XPath Functions.

XML Path Language (XPath). Resin can use XPath, the XML Path Language, to select nodes from an XML tree. The XPath language is exceptionally rich.

XML Path Language (XPath) is a general-purpose query notation for addressing and filtering the elements and text of XML documents. XPath expressions can address parts of an XML document; manipulate strings, numbers, and Booleans; and can match a set of nodes in the document.

XML Path Language is used for locating XML objects.

Introducing XSLT and XPath

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 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.

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.

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.
