Description

CasToInlineXml adds indentation between adjacent XML elements. E.g. for a single character document with a single annotation covering that one character, it will write:

<?xml version="1.0" encoding="UTF-8"?>
<Document>
    <uima.tcas.DocumentAnnotation sofa="Sofa" begin="0" end="1" language="x-unspecified">
        <uima.tcas.Annotation sofa="Sofa" begin="0" end="1"> </uima.tcas.Annotation>
    </uima.tcas.DocumentAnnotation>
</Document>

I think it should instead write everything in a single line, that is:

<?xml version="1.0" encoding="UTF-8"?>
<Document><uima.tcas.DocumentAnnotation sofa="Sofa" begin="0" end="1" language="x-unspecified"><uima.tcas.Annotation sofa="Sofa" begin="0" end="1"> </uima.tcas.Annotation></uima.tcas.DocumentAnnotation></Document>

I believe this could be fixed by replacing the line:

XMLSerializer sax2xml = new XMLSerializer(byteArrayOutputStream);

with the line:

XMLSerializer sax2xml = new XMLSerializer(byteArrayOutputStream, false);

I think it's a bug that CasToInlineXml is changing the character offsets, but I would also be happy if there was an alternate constructor or a method on CasToInlineXml that allowed disabling the formatting.
