Java Docx4j两个单词文档之间的差异

我需要检查两个单词docx文件之间的差异。Iam使用docx4j。 首先，我必须更改SmartXMLFormatter：

    public SmartXMLFormatter(Writer w) throws IOException {
    this.xml = new XMLWriterNSImpl(w, false);
    if (this.writeXMLDeclaration) {
      this.xml.xmlDecl();
      this.writeXMLDeclaration = false;
    }

    this.xml.setPrefixMapping("http://schemas.openxmlformats.org/wordprocessingml/2006/main", "w");
    this.xml.setPrefixMapping("http://schemas.microsoft.com/office/word/2010/wordml", "w14");
    this.xml.setPrefixMapping("http://schemas.microsoft.com/office/word/2012/wordml", "w15");
    this.xml.setPrefixMapping("http://schemas.openxmlformats.org/officeDocument/2006/relationships", "r");
    this.xml.setPrefixMapping("http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing", "wp");
    this.xml.setPrefixMapping("http://schemas.openxmlformats.org/drawingml/2006/main", "a");
    this.xml.setPrefixMapping("http://schemas.openxmlformats.org/drawingml/2006/picture", "pic");

    this.xml.setPrefixMapping(Constants.BASE_NS_URI, "dfx");
    this.xml.setPrefixMapping(Constants.DELETE_NS_URI, "del");
    this.xml.setPrefixMapping(Constants.INSERT_NS_URI, "ins");
  }

在我没有俄语字母的情况下更改代码后，一切都很好。 但当我用俄语字符区分2个docx文档时，会出现以下异常：

    org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 10510; Präfix "w14" für Attribut "w14:paraId", das mit Elementtyp "w:p" verknüpft ist, ist nicht gebunden.

编辑：

publicstaticvoidopenresult（字符串nodename，Writer out）抛出IOException{
//一般来说，我们需要避免直接写出来。。。
//因为它可以在格式化程序输出到达之前发生
//未正确声明名称空间：
//4种选择：
// 1:
//OpenElementEvent containerOpen=new OpenElementEventNSImpl（xml1.getNamespaceURI（），rootNodeName）；
//formatter.format（containerOpen）；
////AttributeEvent wNS=新的AttributeEventSimpl（“http://www.w3.org/2000/xmlns/“，“w”，
// //       "http://schemas.openxmlformats.org/wordprocessingml/2006/main");
////formatter.format（wNS）；
//但是AttributeEvent在这个过程中太晚了，无法设置映射。
//所以你可以评论一下。
//但是您仍然需要在中添加w:和其他名称空间
//SmartXMLFormatter构造函数。因此，我们不妨做2：
//2：将所有已知名称空间粘贴到上面的根元素上
//3：修复SmartXMLFormatter
//选择2.因为这是明确的
out.追加（“”）；
}

好的，我自己解决了。我向Docx4jDriver中添加了以下代码：请参见上文：D抱歉，我是stackoverflow的新手；）但是现在当我运行到文档时，每一个都运行得很完美，但是当文件中存在一些差异时，所有的内容都会生成。但有人说我失败了…我想没有人能帮我。。。

public static void openResult(String nodename,  Writer out) throws IOException {
        // In general, we need to avoid writing directly to Writer out...
        // since it can happen before formatter output gets there

        // namespaces not properly declared:
        // 4 options:
        // 1:
        // OpenElementEvent containerOpen = new OpenElementEventNSImpl(xml1.getNamespaceURI(), rootNodeName);
        // formatter.format(containerOpen);
        // // AttributeEvent wNS = new AttributeEventNSImpl("http://www.w3.org/2000/xmlns/" , "w",
        // //       "http://schemas.openxmlformats.org/wordprocessingml/2006/main");
        // // formatter.format(wNS);
        // but AttributeEvent is too late in the process to set the mapping.
        // so you can comment that out.
        // But you still have to add w: and the other namespaces in
        // SmartXMLFormatter constructor. So may as well do 2.:
        // 2: stick all known namespaces on our root element above
        // 3: fix SmartXMLFormatter
        // Go with option 2 .. since this is clear
        out.append("<" + nodename
