在 Java 中将 XML 文档写入文件时出错

我正在尝试将 org.w3c.dom.Document 写入文件。获取

String URL = "http://...."
DOMParser parser = new DOMParser();
Document doc = null;
try {
    parser.parse(new InputSource(URL));
    doc = parser.getDocument();
} catch () {}

我从然后我将此 Document 写入文件中

TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File(file));
transformer.transform(source, result);

Document在执行此操作时，我不断收到以下错误

ERROR:  'Namespace for prefix 'xlink' has not been declared.'

可能出了什么问题？谢谢

I am trying to write org.w3c.dom.Document to a file. I get the Document from

String URL = "http://...."
DOMParser parser = new DOMParser();
Document doc = null;
try {
    parser.parse(new InputSource(URL));
    doc = parser.getDocument();
} catch () {}

Then I write this Document to a file using

TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File(file));
transformer.transform(source, result);

While doing this I keep getting the following error

ERROR:  'Namespace for prefix 'xlink' has not been declared.'

What might be wrong? Thanks

我建议使用不同的库，例如 Dom4J，而不是尝试通过 Java 中的内置 XML API 来解决问题。 Dom4J 设计得更好，使您的代码更具可读性：

Document doc = new SAXReader().read(inputStream);
new XMLWriter(outputStream).write(doc);

这些都不会与 FactoryFactoryFactoryFactories 混在一起。

我知道这并不能直接回答您的问题，但希望它无论如何都会有所帮助。 Dom4j 知道如何与 Java XML API 通信，因此您可以混合搭配它们以满足您的需求。如果您想使用 XSLT，您甚至可以将其插入 Xalan 或类似的东西中。

I recommend using a different library such as Dom4J rather than trying to fight your way through the built-in XML API in Java. Dom4J is better designed and makes your code much more readable:

Document doc = new SAXReader().read(inputStream);
new XMLWriter(outputStream).write(doc);

None of this mucking around with FactoryFactoryFactoryFactories.

I know this doesn't directly answer your question but hopefully it will help anyway. Dom4j knows how to talk to the Java XML API so you can mix and match them to suit your needs. You can even plug it into Xalan or something similar if you want to use XSLT.
