Now, let's assume that all of the command-line args are file names, and we'll try to parse them one-by-one using the parse method from the XMLReader interface: import To find out about the start and end of the document, the client application implements the start Document and end Document methods: method once (even if there have been errors). Default Handler; public class My SAXApp extends Default Handler Start document Start element: poem Characters: "\n" Start element: title Characters: "Roses are Red" End element: title Characters: "\n" Start element: l Characters: "Roses are red," End element: l Characters: "\n" Start element: l Characters: "Violets are blue;" End element: l Characters: "\n" Start element: l Characters: "Sugar is sweet," End element: l Characters: "\n" Start element: l Characters: "And I love you." End element: l Characters: "\n" End element: poem End document Note that even this short document generates (at least) 25 events: one for the start and end of each of the six elements used (or, if you prefer, one for each start tag and one for each end tag), one of each of the eleven chunks of character data (including whitespace between elements), one for the start of the document, and one for the end.
It's a really huge library and makes a free CAD application possible in the first place, by providing some packages which would be hard or impossible to implement in an Open Source project: To learn more about Open Cas Cade take a look at the Open Cas Cade page or
Version: 4.1.x or higher License: GPL v2.0/v3.0 or Commercial (from version 4.5 on also LPGL v2.1) I don't think I need to tell a lot about Qt.
Finally, SAX2 reports regular character data through the characters method; the following implementation will print all character data to the screen; it is a little longer because it pretty-prints the output by escaping special characters: import
These are libraries which are not changed in the Free CAD project.
The used libraries are: If you are using Windows, consider using Lib Pack instead of downloading and installing all the stuff on your own.
Version: 2.5 or higher License: Python 2.5 license You can use the source or binary from or use alternetivly Active State Python from though it is a little bit hard to get the debug libs from Active State.For a closer look to Python see: Python you may ask.There are some reasons: So far I used different scripting languages in my professional life: Python is more OO then Perl and Tcl, the code is not a mess like in Perl and VB.It is also well tested and has a strong back hold in the open source community.Goes to Guido van Rossum and a lot of people made Python such a success!The SAX driver will signal the start and end of elements in much the same way, except that it will also pass some parameters to the start Element and end Element methods: contains the raw XML 1.0 name, which you must use for all elements that don't have a namespace URI. You may also work with documents that have some elements (and attributes) with namespaces, and some without.
