DOM Extender
Keywords: PARSE PARSING HTML XML DOM
Graphical Dynamics is making available for download our WIL extender for parsing HTML/XML files.
http://www.graphicaldynamics.com/wxdom/wxdom44i.zip
As always, any bug reports will be appreciated:http://www.graphicaldynamics.com/techforum/viewforum.php?f=9
The wxdom44i.dll extender was originally developed for use in AutoIntern 2.0, our job scheduler app. In fact several of our sample scripts use it. But now we're making it available for standalone use by any WinBatch script as well.
Our DOM extender lets you read an HTML or XML file, search for elements by various criteria, change data, move/delete/insert elements, etc.
The API is loosely based on the standard DOM model, but was designed to be simpler to use within the WIL-programming paradigm. The DOM extender is also more forgiving of coding errors in XML files than, for example, Microsoft's MSMXL parser.
The zip file comes with the DLL, a CHM help file, and three sample scripts:
DataFilter - Demonstrates parsing XML, finding elements, deleting & inserting elements.
RSSViewer - Downloads XML files (RSS feeds in one of several RSS formats) from blogs, picks out the stories from the last 48 hours, and builds up an HTML file of links.
Search Engine Rank analyzer - You specify a keyword & URL, and this searches four different search engines for that keyword, parses the resulting HTML files, and determines the result where that URL shows up for it.
I'm curious to know if you think this is easier to use/more useful than the other parsers out there. We're going to continue supporting this, of course, since we use it in our product, but is it worth it to you to see it continue to be supported?
Enjoy!

======================================= Version 10010 Oct 22, 2007 FIX: Removed the 128-character limit on pathnames that the extender would recognize. Version 10011 Oct 29, 2007 IMPROVED: The search functions that take a tagname or attribute name now accept wildcarded names using "*" & "?". (DOMGet1stChild, DOMGetElementsByTagname, DOMGetAttr, etc.) Version 10012 Nov 06, 2007 NEW: Namespace functions. These start with "NS". (Most of them are still untested & these are marked as such in the help file.) FIX: If you called a search function and the search string was wildcarded, the functions would match a blank item as well. (DOMGetLinksByHRef would match an empty href value, DOMGetElementsByTagname would match a tag with no name, etc.) FIX: DOMGetLinksByHRef was performing a case-sensitive search, which is contrary to the documentation. Version 10013 Nov 08, 2007 IMPROVED: The namespace functions have all been alpha-tested. We're throwing them out to the tender mercies of all you beta-testers. Please report any bugs to the AutoIntern tech support board: http://www.graphicaldynamics.com/forum Version 10014 Nov 12, 2007 NEW: Added the NSSetPrefixes function. This function does a wholesale rename of namespace prefixes within a specified node and its descendants. IMPROVED: The tagname parameter in DOMGetElementsByTagname now defaults to "*". This will return all descendant elements of the specified node, regardless of their tagnames. FIX: If you called a search function, it would always act as if you were passing it a wildcarded expression ending in "*". (DOMGetElementsByTagname(hNode,"t") would find <table>, <tr>, <td>, etc.) FIX: If you called DOMGetElementsByTagname and specified "*" for the tagname, in addition to finding elements it would also match the document root, processing instructions, and comments. FIX: The interior text of CDATA sections wasn't being recorded correctly. Version 10015 Nov 13, 2007 NEW: DOMGetNodesByType. This is similar to DOMGetElementsByTagname, but lets you get all instances of nodes of a specific type or of any type. NEW: DOMGetNodeData, DOMSetNodeData. These let you get/set the text of comments, processing instructins, CDATA or other sections, and plaintext nodes. FIXED: DOMGetOuterHTML wasn't reproducing CDATA sections correctly. Version 10016 Nov 16, 2007 IMPROVED: When you specify a node by its node path, you can have embedded blanks between parts of the path or between tagnames and the [indexes] afterwards. FIXED: If you specified an incorrect tagname in a node path, it wouldn't necessarily return a node handle of 0 like it should. Version 10027 May 30, 2008 NEW: DOMGetDocEncoding, DOMSetDocEncoding. these let you get/set a document's character encoding, the byte order (if using 16-bit characters), and whether or not to include a byte-order mark when writing out the file. IMPROVED: Better handling of 16-bit XML files in both byte orders, better reading of the byte-order marks, and better determination of the character size & encoding if there is no BOM. Version 10028 Aug 20, 2008 NEW: DOMGetVersion. This returns the extender's integer version number. For example, 10028. FIX: If you created an XML/HTML file from scratch without first reading it in via DOMParseFile, and you didn't also call DOMSetDocEncoding, when you later called DOMWriteFile it would GP fault. Version 10029 Sep 12, 2009 FIX: DOMGetElementsByAttrValue (and DOMGetXByY generally except for DOMGetCommentsByText) weren't returning all the matching nodes. =======================================
