How to create TiXMLDocument() with XML in mem

[karam_chand]

Hello,

I have XML data in memory. Can I create an TiXMLDOcument() of it and work with it?

Basically, my XML data is in memory and not in file, so I just want to use it?

There is a Parse( const char* ) method just for this.

I was also trying to figure out how to parse an encrypted XML file, if it's decrypted in memory, i have seen this Parse( const char* ) function but there's no explanation nor anything for it.

I don't know what is this for. any example of how to use it would help..

This code shows how to use Parse() with a plain, unencrypted, normal char array.

It is taken out of tinyxml_2_2_1*.tar.gz tinyxml\xmltest.cpp, just below where main() starts (anything beginning with "//" is my editing):

    const char* demoStart =
        "<?xml version=\&quot;1.0\&quot;  standalone='no' >\n"
        "<!-- Our to do list data -->"
        "<ToDo>\n"
        "<!-- Do I need a secure PDA? -->\n"
        "<Item priority=\&quot;1\&quot; distance='close'> Go to the <bold>Toy store!</bold></Item>"
        "<Item priority=\&quot;2\&quot; distance='none'> Do bills   </Item>"
        "<Item priority=\&quot;2\&quot; distance='far &amp; back'> Look for Evil Dinosaurs! </Item>"
        "</ToDo>";

    //... irrelevant stuff edited out for clarity
   
    TiXmlDocument doc( "demotest.xml" );
    doc.Parse( demoStart );

    if ( doc.Error() )
    {
        // document failed to load - handle in whatever way is best for your app
        printf( "Error in %s: %s\n", doc.Value(), doc.ErrorDesc() );
        exit( 1 );
    }
   
    // document loaded ok now

I recently wrote some code to read a gzip'd xml file (.svgz) into memory, uncompress it in memory, then pass the raw pointer to TinyXml. Works wonderfully.

OK that's nice now, i understand but i wish if tiny had some interactive tuts explaining every thing Frequently asked here in forums :(
