使用 DOM Parser 解析 XML

Question

我正在使用 DOM 解析器来解析 XML。 xml格式为：

<PriceList>
        <PriceTag>
            <Pricing priceCode = "EATIN">
                <Price></Price>
                <Tax
                    taxCode = "ALWAYS"
                    rule = "TAX_CHAIN"
                    entry = "4"/>
            </Pricing>
            <Pricing priceCode = "TAKEOUT">
                <Price></Price>
                <Tax
                    taxCode = "ALWAYS"
                    rule = "TAX_CHAIN"
                    entry = "4"/>
            </Pricing>
            <Pricing priceCode = "OTHER">
                <Price></Price>
                <Tax
                    taxCode = "ALWAYS"
                    rule = "TAX_CHAIN"
                    entry = "4"/>
            </Pricing>
        </PriceTag>
    </PriceList>

如果 priceCode = "EATIN"，我想读取价格。

谁能帮我实现这个。

尝试替换此行 fileName = ((FileSplit)context.getInputSplit()).getPath().toString(); 与 fileName = context.getConfiguration().get("mapreduce.input.fileinputformat.inpu‌​tdir", null);
