http://nagoya.apache.org/bugzilla/show_bug.cgi?id=15569 XalanDocument doesnīt work as ParsedSource / stringstream doesnīt work as input after it has been used as input Summary: XalanDocument doesnīt work as ParsedSource / stringstream doesnīt work as input after it has been used as input Product: Xerces-C++ Version: 2.1.0 Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Major Priority: Other Component: Build AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Hi, I use MSVC 6.0 on Windows NT. I maybe found some Bugs in your C++ API, that I didnīt understand. It could be that iīm too stupid to understand the API, but please try the Source Code iīm going to attach. I just tried to use the Result of one Transformation for the next Transformation. Therefore I use an created but empty XalanDocument as Result Target. I take this and use it as InputSource for the next Transformation. It didnīt work, so I decided to use stringstream instead of XalanDocument. Didnīt work either. I even tried to convert all to Xerces DOM_Document and back. Didnīt work either. I tried creating my empty XalanDocument through various ParserLiasion. Itīs just impossible. The only way I encountered to process the Output of a Transformation is to write it to a file, and use that file as Input. That just canīt be true? If it is like that, than please do so remarks in your Documentation. (if there are remarks, i didnīt find them...) I tried to find the solution myself, but iīm not a crack... But what makes me scratch my head about your Design, is that any InputSource for transformations is run through a parser... Later in the doTransform the XalanDocument is extracted again. If you got any Questions, feel free to eMail me. It would be nice to get an reply, what was wrong (especially if iīm just too stupid..). Source Code: (I Hope itīs not too long but itīs a working Testframe with Comments on what didnīt work, and how i got around it...) bool func() { XMLPlatformUtils::Initialize(); // Initialize Xalan.
