How simply save XML document to string,to file and from file

[pdf]

Hello,

I work with a simple (small) XML structure as for exemple :

Code: Select all

Poco::AutoPtr< Poco::XML::Document> data;
data->appendChild( data->createElement( typeid( *this).name()));
data->documentElement()->setAttribute( "creation", _creation.toString());
data->documentElement()->setAttribute( "emission", _emission.toString());

and i want simply :
- convert the full XML document to a string :

Code: Select all

std::string s = data->toString();

- reload the XML document from the previous string :

Code: Select all

data->fromString( s);

- save the XML document to a disk file :

Code: Select all

data->saveToFile( "c:\dump.xml");

- reload the document from the file :

Code: Select all

data->loadFromFile( "c:\dump.xml");

How to do that ?

Best regards.
