字符串作为文档

发布于 2024-10-04 02:53:32 字数 407 浏览 3 评论 0原文

我正在遵循有关使用 XPath 解析 XML 的教程，它给出了打开文档的以下示例：

DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
domFactory.setNamespaceAware(true); // never forget this!
DocumentBuilder builder = domFactory.newDocumentBuilder();
Document doc = builder.parse("books.xml");

我想做的是更改它，以便 Document 正在读取 我已经创建的 String 变量，而不是从文件中读取。我怎样才能做到这一点？

I'm following this turorial on parsing XML with XPath, and it gives the following example to open a document:

DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
domFactory.setNamespaceAware(true); // never forget this!
DocumentBuilder builder = domFactory.newDocumentBuilder();
Document doc = builder.parse("books.xml");

What I would like to do, is change that so that the Document is reading a String variable that I already have made, instead of reading from a file. How can I do that?

builder.parse(new InputSource(new StringReader("<some><xml></xml></some>")));

builder.parse(new InputSource(new StringReader("<some><xml></xml></some>")));

请查看此处

DocumentBuilderFactory dbf =
        DocumentBuilderFactory.newInstance();
    DocumentBuilder db = dbf.newDocumentBuilder();
    InputSource is = new InputSource();
    is.setCharacterStream(new StringReader(xmlRecords));

    Document doc = db.parse(is);

Look here

DocumentBuilderFactory dbf =
        DocumentBuilderFactory.newInstance();
    DocumentBuilder db = dbf.newDocumentBuilder();
    InputSource is = new InputSource();
    is.setCharacterStream(new StringReader(xmlRecords));

    Document doc = db.parse(is);

你可以试试这个：

public static Document stringToDom(String xmlSource) 
        throws SAXException, ParserConfigurationException, IOException {
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = factory.newDocumentBuilder();
    return builder.parse(new InputSource(new StringReader(xmlSource)));
}

You may try this one:

public static Document stringToDom(String xmlSource) 
        throws SAXException, ParserConfigurationException, IOException {
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = factory.newDocumentBuilder();
    return builder.parse(new InputSource(new StringReader(xmlSource)));
}
