如何使用xmlStreamReader以字符串形式获取XML文件的全部内容?

问题描述

我在应用程序的一部分中，可以访问表示xmlStreamReader rel ="nofollow"> XML 文件需要完全读入 String .

I'm in a part of an application where I have an access to the xmlStreamReader which is representing the XML file needed to be fully read into a String.

有没有一种方法可以获取XML内容，而无需构建另一个 xmlStreamReader 或在文件?

Is there a way to obtain the XML content without building another xmlStreamReader or using another stream on the file?

推荐答案

import javax.xml.stream.XMLStreamReader;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.TransformerFactoryConfigurationError;
import javax.xml.transform.stax.StAXSource;
import javax.xml.transform.stream.StreamResult;

private String getOuterXml(XMLStreamReader xmlr) throws TransformerConfigurationException,
    TransformerFactoryConfigurationError, TransformerException
{
    Transformer transformer = TransformerFactory.newInstance().newTransformer();
    StringWriter stringWriter = new StringWriter();
    transformer.transform(new StAXSource(xmlr), new StreamResult(stringWriter));
    return stringWriter.toString();
}
