解决方案

试试这个：使用Java教程解析XML [ ^ ]

<?xml version="1.0"?>
<BigDataComparator xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" FileType="TestCase">
    <TestCase name="MyFirstTestCase" description="This is very first test case">
        <SourceFeed type="HDFS Flat File">
            <FileName>hdfs://172.20.15.17:8020/home/lnt/Hadoop/hadoop/ComparatorInput/sourceFile.txt</FileName>
            <Delimiter>|</Delimiter>
            <StringQualifier>"</StringQualifier>
            <CommentCharacter>#</CommentCharacter>
        </SourceFeed>
        <TargetFeed type="HDFS Flat File">
            <FileName>hdfs://172.20.15.17:8020/home/lnt/Hadoop/hadoop/ComparatorInput/targetFile.txt</FileName>
            <Delimiter>|</Delimiter>
            <StringQualifier>"</StringQualifier>
            <CommentCharacter>#</CommentCharacter>
        </TargetFeed>
        <TableMapping name="">
        </TableMapping>
        <GeneralOptions ignorecase="true" trimdata="false" />
    </TestCase>
</BigDataComparator>
