<p>Michael,</p>
<p>yes you can get the VRT XML text with:</p>
<p>poVRTDS->GetMetadata("xml:VRT")[0]</p>
<p>If you can submit a pull request documenting that, that would be
welcome</p>

<div>int nBand;<br>
GDALDriver *poDriver = (GDALDriver *) GDALGetDriverByName(

poVRTDS = poDriver->CreateCopy( "", poSrcDS, FALSE, NULL,
NULL, NULL );<br>
<div>//</div>
<div><br>
</div>
<div>Is there a way to obtained the VRT XML text representing
poVRTDS without writing to an actual file? </div>
<div><br>
</div>
<div>Sorry if this is obvious, haven't been able to find an
example that does what I want. I've seen examples using
GetMetadataItem from a band for parts of the XML, but can't
see how to get the entire thing. </div>

<div>Thanks for your help. </div>
