Alberto, Thanks again. Everything worked fine. By the way, as I use getNodeValue and getNodeName to process and assign them to my C++ structures I need to parse the XMLCh* returned value to String^ buy I couldn't find any way to do it. Any idea?
Jesse, That's a good question..xD. There are many reasons why I am trying to use Xerces in order to parse and create XML files. Maybe you'll find them stupid. Firstly, I am an absolute newbie with C++ as with Xerces (as you have already realized). So, I did no research on XML classes offered by the .NET framework as I didn't know them. Secondly, I am developing an application based on a previous version which was developed by another person, who based his app on Xerces to parse XML files. The problem is that his design didn't take into account creating or writing on XML files, only parsing and reading, so he used the SAX API. Then, I had to switch from SAX to DOM and facing all the problems it implies (creating a NEW app). Thirdly, I thought I could find some help if I based my design on a open source solution like Xerces is, and here it is. Then, if you tell me that it is worth for me working with the System:XML files, then I would think about it..haha. But then, what is Xerces for if everybody can manage their XML files with these classes?
