Re: How to parse char strings using DOMParser::parse()

[Don Mastrovito]

Carlo,

This code snippet demonstrates basic string and file parsing.

     const bool  LoadFromStream = true;    // Set to false for file i/o
     const std::string MyFileName ("C:\TEMP\TEST.XML");
     const std::string MyStream ("<?xml version='1.0' encoding='utf-8' 
?><TAG>My Data</TAG>");
     char       *BufferID = NULL;
     MemBufInputSource *MemBufIS = NULL;

     DOMParser *Parser = new DOMParser;
     Parser->setCreateEntityReferenceNodes(false);
     Parser->setDoNamespaces(false);
     Parser->setDoSchema(false);
     Parser->setDoValidation(false);
     Parser->setToCreateXMLDeclTypeNode(true);
     Parser->setValidationScheme(false);

     if (!LoadFromStream)
         Parser->parse(MyFileName.c_str());
     else
     {
         MemBufIS = new MemBufInputSource(
             (const XMLByte*)MyStream.c_str(),           // Stream pointer
             MyStream.size()+ 1,             // Byte (not character) count
             &BufferID,                          // Buffer ID (becomes 
System ID)
             false);                             // Copy (not adopt) 
caller's buffer

         if (MemBufIS == NULL)
         {
             // Handle errors here
         }

         Parser->parse(*MemBufIS);
     } // End if (LoadFromStream)

     DOM_Node Root = Parser->getDocument();
     DOM_Document Document = Parser->getDocument();
     if (MemBufIS != NULL)
         delete MemBufIS;

This example uses STL string references.  Traditional C-style strings can 
be used as well by substituting char*, pointers, and strlen() for 
std::string, c_str() and size() respectively.

HTH,
Don
