tinyxml2::XMLPrinter class
Printing functionality. The XMLPrinter gives you more options than the XMLDocument::Print() method. It can: -# Print to memory. -# Print to a file you provide. -# Print XML without a XMLDocument. Print to Memory @verbatim XMLPrinter printer; doc.Print( &printer ); SomeFunction( printer.CStr() ); @endverbatim Print to a File You provide the file pointer. @verbatim XMLPrinter printer( fp ); doc.Print( &printer ); @endverbatim Print without a XMLDocument When loading, an XML parser is very useful. However, sometimes when saving, it just gets in the way. The code is often set up for streaming, and constructing the DOM is just overhead. The Printer supports the streaming case. The following code prints out a trivially simple XML file without ever creating an XML document. @verbatim XMLPrinter printer( fp ); printer.OpenElement( "foo" ); printer.PushAttribute( "foo", "bar" ); printer.CloseElement(); @endverbatim
