如何在Java中编写unicode字符0x{2}

我尝试使用"\u0002",但似乎无效。

我需要找到这个字符的原因是因为我需要在XML文件中替换它,然后才能解析它。

解析时提到的错误:An invalid XML character (Unicode: 0x{2}) was found in the value of attribute "{1}" and element is "4".并替换\u0002无法解决错误。

这就是我解析的方式:

try {
    // Fixing any invalid characters in the XML file
    fixXMLFile(xmlFile);

    // Get a factory
    SAXParserFactory spf = SAXParserFactory.newInstance();

    // Get a new instance of parser
    SAXParser sp = spf.newSAXParser();

    // Parse the file and also register this class for call backs
    sp.parse(xmlFile, this);

} catch(Exception e) {
    System.out.println(e.getLocalizedMessage());
}

修复方法:

private void fixXMLFile(File xmlFile) throws IOException {
    File tempFile = File.createTempFile("dont_delete", ".tmp");
    FileWriter fw = new FileWriter(tempFile);

    Reader fr = new FileReader(xmlFile);
    BufferedReader br = new BufferedReader(fr);

    int sdds = 0;
    while(br.ready()) {
        String tmp = br.readLine();
        if (tmp.contains("\u0002")) System.out.println(++sdds);
        fw.write(tmp.replaceAll("\u0002", "") + "\n");
    }

    fw.close();
    br.close();
    fr.close();

    // Finally replace the original file.
    tempFile.renameTo(xmlFile);
}

我找到了。 Java中的0x{2}错误消息中的"\u0004"。替换它可以消除错误消息。

不允许使用该字符是XML,请参阅Wikipediate for ref:http://en.wikipedia.org/wiki/Valid_characters_in_XML#XML_1.0
