未聲明的命名空間與鄰：allowincell在docx4j Differencer.diff（）調用

當一個文檔轉換過程的結果比較原始與docx4j，我們得到以下錯誤爲我們的測試情況之一：未聲明的命名空間與鄰：allowincell在docx4j Differencer.diff（）調用

com.topologi.diffx.xml.UndeclaredNamespaceException: The namespace URI "urn:schemas-microsoft-com:office:office for allowincell" has not been mapped to any prefix.

我消除利用該方法在原始文檔進行比較，以本身被改造的探討過程中引入的誤差（基於this answer）的可能性：

private static final String compareToSelf(File fileToCompare) throws Docx4JException { 
    WordprocessingMLPackage olderPackage = WordprocessingMLPackage.load(fileToCompare); 
    WordprocessingMLPackage newerPackage = WordprocessingMLPackage.load(fileToCompare); 

    Body newerBody = newerPackage.getMainDocumentPart().getJaxbElement().getBody(); 
    Body olderBody = olderPackage.getMainDocumentPart().getJaxbElement().getBody(); 

    java.io.StringWriter sw = new java.io.StringWriter(); 
    javax.xml.transform.stream.StreamResult result = new javax.xml.transform.stream.StreamResult(sw); 
    Calendar changeDate = null; 

    Differencer pd = new Differencer(); 
    pd.setRelsDiffIdentifier("blagh"); // not necessary in this case 
    pd.diff(newerBody, olderBody, result, "someone", changeDate, 
       newerPackage.getMainDocumentPart().getRelationshipsPart(), 
       olderPackage.getMainDocumentPart().getRelationshipsPart()); 

    return sw.toString(); 
}

的Stac ķ跟蹤：

我解壓* .docx文件和o:allowincell似乎是在包含document.xml的<w:document>標籤與xmlns:o="urn:schemas-microsoft-com:office:office"正確映射。

測試文件可以從這裏纔可下載：https://docs.google.com/open?id=0B6_h2TfqvEdeZE43X3RSWnFIZHc

就如何解決這個問題的任何想法？

此警告在執行過程中也會出現，不確定它是否相關：WARN [org.docx4j.openpackaging.contenttype.ContentTypeManager] - ' – 2012-08-13 14:02:20

在Docx4jDriver在管線192和206有：

e.setAttributeNS("http://www.w3.org/2000/xmlns/", "xmlns:w", 
      "http://schemas.openxmlformats.org/wordprocessingml/2006/main");

你可能需要添加的xmlns：○。最終，需要對代碼進行改進以自動添加所有相關的名稱空間。
