Hi people
I'm trying to extract a number from an XML element...for now, just a
simple test - and that is creating problems for me!
Can someone please tell me what I'm doing wrong in this short example?
My XML test file:
<level1Product xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="mytest_tiny.xsd">
<imageDataInfo>
<pixelValueID>RADAR BRIGHTNESS</pixelValueID>
<imageRaster>
<numberOfRows>3600</numberOfRows>
</imageRaster>
</imageDataInfo>
</level1Product>
My code extract:
XMLCh* numberOfRows = XMLString::transcode("numberOfRows");
doc->getElementsByTagName(numberOfRows);
cout << "# elems found: " <<
doc->getElementsByTagName(numberOfRows)->getLength() << endl; // returns
1 (as expected)
cout << "The number of rows is: " <<
XMLString::transcode(doc[0].getTextContent()) << endl; // returns
nothing - why?
When I do this, an empty string is output. I can add ->getLength() and
it returns 1, so I know it got the element.
What do I need to change to actually retrieve the value "3600" ?
Thanks lot!
Adrian
