Detailed Description

Print to memory functionality. The TiXmlPrinter is useful when you need to:

Print to memory (especially in non-STL mode)
Control formatting (line endings, etc.)

When constructed, the TiXmlPrinter is in its default "pretty printing" mode. Before calling Accept() you can call methods to control the printing of the XML document. After TiXmlNode::Accept() is called, the printed document can be accessed via the CStr(), Str(), and Size() methods.

TiXmlPrinter uses the Visitor API.

	TiXmlPrinter printer;
	printer.SetIndent( "\t" );

	doc.Accept( &printer );
	fprintf( stdout, "%s", printer.CStr() );

const char* TiXmlPrinter::CStr ( ) [inline]

Return the result.

Definition at line 1773 of file tinyxml.h.

{ return buffer.c_str(); }

const char* TiXmlPrinter::Indent ( ) [inline]

Query the indention string.

Definition at line 1757 of file tinyxml.h.

{ return indent.c_str(); }

const char* TiXmlPrinter::LineBreak ( ) [inline]

Query the current line breaking string.

Definition at line 1764 of file tinyxml.h.

{ return lineBreak.c_str(); }

void TiXmlPrinter::SetIndent ( const char * _indent ) [inline]

Set the indent characters for printing. By default 4 spaces but tab () is also useful, or null/empty string for no indentation.

Definition at line 1755 of file tinyxml.h.

{ indent = _indent ? _indent : "" ; }

void TiXmlPrinter::SetLineBreak ( const char * _lineBreak ) [inline]

Set the line breaking string. By default set to newline (
). Some operating systems prefer other characters, or can be set to the null/empty string for no indenation.

Definition at line 1762 of file tinyxml.h.

{ lineBreak = _lineBreak ? _lineBreak : ""; }

void TiXmlPrinter::SetStreamPrinting ( ) [inline]

Switch over to "stream printing" which is the most dense formatting without linebreaks. Common when the XML is needed for network transmission.
