Victoria,
Thanks.
I just solved this problem. Instead using Sourcewriting Transformer, I
use processPipelineTo() to transform the output to a OuptPutStream
and then I can pass this stream to DOMParser.
Here is part of the code in my java file.
ByteArrayOutputStream stream = new ByteArrayOutputStream();
String uri = "multchoice/" + problemname;
processPipelineTo(uri, dataHash, stream);
ByteArrayInputStream instream = new
ByteArrayInputStream(stream.toByteArray());
MathCal mathcal = new MathCal();
interResult = mathcal.doMathCalculate(dataHash, instream).toString();
// MathCal.java
......
public Object DoMathCalculate(Hashtable ht, ByteArrayInputStream stream) {
MathMLParser parser = new MathMLParser();
InputSource file = new InputSource(stream);
try {
parser.parse(file);
} catch(Exception e) {
e.printStackTrace();
}
.......
