Je sais pas pour vous, mais à chaque fois que je dois utiliser et donc créer une requete XPath il est toujours compliqué de mettre en place un systéme pour tester nos expressions. Quand j'utilise .net ça se termine souvent par un point d'arrêt au moment de faire la requête XPath et je testais mes différentes expressions directement en debug. Sinon, si j'avais à faire une requete XPath dans du XSLT je n'avais pas encore trouvé de bidouille pour tester :-) C'était donc vraiment pas l'idéal ! J'ai par hasard découvert aujourd'hui (merci Etienne et Danuz) un petit logiciel en freeware vraiment sympathique : XPathBuilder ! Evidemment il est écrit en .net.
This works on AutoPager 0.5.1.4 or newer version. This is the recording of the steps to create the rule for http://www.pspad.com/en/pspad-extensions.php. This demo shows how to create AutoPager rules for the pages which don't have "Next" in links. They only have a navbar includes all the page numbers like this: Page: [1], 2, 3, 4. The final link xpath get in this tutorial is: //div[@id='obspoz']/p/text()[contains(.,'[')]/following-sibling::a[1] Steps explains: //div[@id='obspoz']/p :select the navbar. //div[@id='obspoz']/p/text() : select the texts in the navbar since current page number does not have a node //div[@id='obspoz']/p/text()[contains(.,'[')] : select the text for the current page number. It will be easier if the current page number has a node, for example if it's a span with class='current': //div[@id='obspoz']/p/span[@class='current']. //div[@id='obspoz']/p/text()[contains(.,'[')]/following-sibling::a[1] : select the first link after the current page number text.
The following form calls a program written in C , that converts a grammar into syntax diagrams. The diagrams can be used for direct printing and inclusion in printable text files. Two examples for a grammar are given (a variant of the EBNF-grammar and the XPath-grammar).
EditiX is a powerful and easy to use XML editor, Visual Schema Editor, XQuery Editor and XSLT debugger for Windows, Linux and Mac OS X designed to help web authors and application programmers take advantage of the latest XML and XML-related technologies such as XSLT / FO, DocBook and XSD Schema. EditiX provides users with an extensive range of XML functionality within a refined IDE that guides you with intelligent entry helpers. EditiX has realtime XPath location and syntax error detection. Helpers are also provided with context syntax popup supporting DTD, Schema and RelaxNG. EditiX supports multiple templates and project management. User can apply XSLT, XQuery or FO Transformation and show the result with a dedicated view. All the process can be managed by shortcuts. Working locally is managed with OASIS XML Catalogs. EditiX includes default templates with XML, DTD, XHTML, XSLT, XSD, XML RelaxNG, SVG, MathML and XML FO.
Script Summary: Add pop-up preview to any site.(Script homepage).....Rules for popup action must be written in "SITEINFO" in proper format. Properties of SITEINFO url (required)(RegExp) : URL to which the rule is applied. targetElement (required)(XPath) : XPath which select "A" elements. When "mouseover" action occurs on them, linked pages (values of "href" attributes) will be fetched. popupElement (required) (XPath) : XPath which select elements in fetched pages. These elements will be appear in tooltips. disabled (optional) : If you want to disable a rule temporally, set "false". style (optional) : CSS attributes of tooltips. Please be careful to write in CamelCase! (border-width -> borderWidth) stripe (optional) : If you set "true", small icons will be appended to elements on which the action will occur.

...generates XPaths while browsing or inspecting HTML/XML/*ML documents; evaluates your XPaths and inspects the results; extracts the content.
A property path expression (or just 'path') is similar to a string regular expression but over properties, not characters. ARQ determines all matches of a path expression and binds subject or object as appropriate. Only one match is recorded - no duplicates for any given path expression, although is the path is used in a situation where it's initial points is already repeated in a pattern, then this duplication is preserved.
RegExp ou XPath appliqué à un graphe? Intéressant, mais peut-être abscons.
]]>Lets you clean up a page by putting instructions in url (css, xpath selecting, regexp and more)
Predicates give you advanced and refined searching capabilities, allowing you to evaluate the values of attributes and the parent and child nodes of a targeted element. Rather than find a wider node set and refine or filter that set programmatically, you can add predicates to your XPaths to find exactly the nodes you want.

What is xpathtool? Short version: xpath query tool for xml and html. Long version: swanky frontend to xsltproc which takes an xpath query and content and spits out the results. Dependencies: xsltproc (comes with libxslt), xmllint (comes with libxml2).
WebPath, my experimental XPath 2.0 engine in Python is now an open source project with a liberal BSD license. I originally developed this during a Yahoo! Hack Day, and now I get to announce it during another Hack Day.
