openxml - 如何以编程方式访问打开的 xml worddoc 文件的内置属性

Question

我想访问打开的 xml word doc 文件的一些内置属性（如作者、上次修改日期等）。我想为此目的使用 open xml sdk2.0。所以我想知道是否有任何类或任何方式可以以编程方式访问这些内置属性。

Answer 1

可以在此处找到对以下方法的说明，但是您几乎需要将要从 core.xml 文件中获取的属性传递给此方法，它将返回值：

public static string WDRetrieveCoreProperty(string docName, string propertyName)
{
   // Given a document name and a core property, retrieve the value of the property.
   // Note that because this code uses the SelectSingleNode method, 
   // the search is case sensitive. That is, looking for "Author" is not 
   // the same as looking for "author".

   const string corePropertiesSchema = "http://schemas.openxmlformats.org/package/2006/metadata/core-properties";
   const string dcPropertiesSchema = "http://purl.org/dc/elements/1.1/";
   const string dcTermsPropertiesSchema = "http://purl.org/dc/terms/";

   string propertyValue = string.Empty;

   using (WordprocessingDocument wdPackage = WordprocessingDocument.Open(docName, true))
   {
      // Get the core properties part (core.xml).
      CoreFilePropertiesPart corePropertiesPart = wdPackage.CoreFilePropertiesPart;

      // Manage namespaces to perform XML XPath queries.
      NameTable nt = new NameTable();
      XmlNamespaceManager nsManager = new XmlNamespaceManager(nt);
      nsManager.AddNamespace("cp", corePropertiesSchema);
      nsManager.AddNamespace("dc", dcPropertiesSchema);
      nsManager.AddNamespace("dcterms", dcTermsPropertiesSchema);

      // Get the properties from the package.
      XmlDocument xdoc = new XmlDocument(nt);

      // Load the XML in the part into an XmlDocument instance.
      xdoc.Load(corePropertiesPart.GetStream());

      string searchString = string.Format("//cp:coreProperties/{0}", propertyName);

      XmlNode xNode = xdoc.SelectSingleNode(searchString, nsManager);
      if (!(xNode == null))
      {
         propertyValue = xNode.InnerText;
      }
   }

   return propertyValue;
}

您还可以使用打包 API：

using System.IO.Packaging.Package;

[...]

using (var package = Package.Open(path))
{
    package.PackageProperties.Creator = Environment.UserName;
    package.PackageProperties.LastModifiedBy = Environment.UserName;
}

这也适用于其他开放 XML 格式，如 power point。

包.保存（）；然后打包。关闭；

我认为这是最好的方法。
