Question

I got some sensible xml data I’d like to parse with Xerces (generated by CodeSynthesis).

On disc it is crypted so I load it, uncrypt it and … I’m stuck as Xerces only takes files as input.

I have thought about overloading one of the ‘readers’ (ie. std::istream or xercesc::InputSource) and fake the disc reading but it seems as quirky as inelegant.

Are there any simpler and neater way to do this?

Thanks!

You can use the MemBufInputSource class:

MemBufInputSource* pMemBufIS = new MemBufInputSource((const XMLByte*)sXmlContent.c_str(), sXmlContent.length(), "SysID", false);
m_saxParser.parse(*pMemBufIS);
delete pMemBufIS;

instead of

m_saxParser.parse(sXmlFilePath.c_str());
