TouchXML installation guide
TouchXML is a libxml API wrapper written in Objective-C and usually helps with all your project XML needs. While writing my post about parsing XML element attributes and putting up demo project I realized that I tend to forget how to add TouchXML to new project, so here goes step-by-step of that procedure:
You can find archives to download in touchcode project downloads . Download TouchXML archive and extract it anywhere you like. It’s common practice to keep such libraries and classes in Developer/ExtraLibs directory.
Enable libxml2 library
First things first, before we actually add TouchXML files, we need to do some project configuration changes, so our project could use libxml library.
Add TouchXML classes
Right click (option click) on your projects “Classes” folder and go to “Add -> Existing files…”
Navigate to the directory where extracted TouchXML is kept and browse deeper to “Common -> Source”. Select everything! And click “Add” obviously.
Now you should see a bunch of new files in your project. I usually group them by selecting files I wish to group and then selecting “Group” in context (right click/option click) menu.
Import TouchXML to your project
That is all the “magic” and you’re good to go. Since, I am not going to write about actually using TouchXML, you can see a nice working example in my previous post.
Error: libxml/tree.h: No such file or directory
… and hundreds of something missing errors. It means that something went wrong with “Header search paths”. Maybe you didn’t added /usr/include/libxml2 or added incorrectly? Check it.
Error: “_xmlDocDumpFormatMemory”, referenced from:- [CXMLDocument description] in CXMLDocument.o
… and tens of errors like this. While errors by them selfs aren’t very expressive, they wish to inform you, that you did not added -lxml2 flag to “Other linker flags”
And that is all for now!
