Reading binary data from Xml

Suppose that I have written binary data into an XML node like this:

MemoryBlock outputData( pOutputData, bytesToWrite );
pRegionXml->setAttribute( "OutputData", outputData.toBase64Encoding() );

How would I then read that data back in most efficiently? Is this correct? Is there a more efficient way?

MemoryBlock myData(2048);
if (myData.fromBase64Encoding( pMyXml->toString() ))
{...}

Since you’re writing the binary data to an attribute of the XML (“OutputData”), you’ll need to pass just the attribute value instead of the entire XML string to fromBase64Encoding().

If you already turned the data into base64 encoding that is inside XML, I wouldn’t really worry anymore about how efficient it is to decode it back to binary. :slight_smile:

Oh, right! I totally missed I was only writing an attribute, not converting an entire node to XML. D’oh! :slight_smile: Thanks!
