使用 XmlDocument 将 XML 导出为 Excel 表

发布于 2024-10-12 00:47:13 字数 1337 浏览 4 评论 0原文

我正在尝试将以下内容写入 XML 文档：

<html xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"
xmlns="http://www.w3.org/TR/REC-html40">

    <head>
     <xml> 
      <x:ExcelWorkbook>
       <x:ExcelWorksheets>
        <x:ExcelWorksheet>
         other code here
        </x:ExcelWorksheet>
       </x:ExcelWorksheets>
      </x:ExcelWorkbook>
     </xml>
    </head>
   </html>

但是，如果我使用以下代码，它会删除“x:”。

System.Xml.XmlDocument document = new System.Xml.XmlDocument();

System.Xml.XmlElement htmlNode = document.CreateElement("html");
htmlNode.SetAttribute("xmlns:o", "urn:schemas-microsoft-com:office:office");
htmlNode.SetAttribute("xmlns:x", "urn:schemas-microsoft-com:office:excel");
htmlNode.SetAttribute("xmlns", "http://www.w3.org/TR/REC-html40");
document.AppendChild(htmlNode);

System.Xml.XmlElement headNode = document.CreateElement("head");
htmlNode.AppendChild(headNode);
headNode.AppendChild(
  document.CreateElement("xml")).AppendChild(
  document.CreateElement("x:ExcelWorkbook"))).AppendChild(
  document.CreateElement("x:ExcelWorksheets")).AppendChild(
  document.CreateElement("x:ExcelWorksheet")).InnerText="other code here";

我怎样才能阻止这种情况发生？

原文

I am trying to write the following into an XML document:

<html xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"
xmlns="http://www.w3.org/TR/REC-html40">

    <head>
     <xml> 
      <x:ExcelWorkbook>
       <x:ExcelWorksheets>
        <x:ExcelWorksheet>
         other code here
        </x:ExcelWorksheet>
       </x:ExcelWorksheets>
      </x:ExcelWorkbook>
     </xml>
    </head>
   </html>

However, if I use the following code, it strips out the 'x:'.

System.Xml.XmlDocument document = new System.Xml.XmlDocument();

System.Xml.XmlElement htmlNode = document.CreateElement("html");
htmlNode.SetAttribute("xmlns:o", "urn:schemas-microsoft-com:office:office");
htmlNode.SetAttribute("xmlns:x", "urn:schemas-microsoft-com:office:excel");
htmlNode.SetAttribute("xmlns", "http://www.w3.org/TR/REC-html40");
document.AppendChild(htmlNode);

System.Xml.XmlElement headNode = document.CreateElement("head");
htmlNode.AppendChild(headNode);
headNode.AppendChild(
  document.CreateElement("xml")).AppendChild(
  document.CreateElement("x:ExcelWorkbook"))).AppendChild(
  document.CreateElement("x:ExcelWorksheets")).AppendChild(
  document.CreateElement("x:ExcelWorksheet")).InnerText="other code here";

How can I stop this from happening?

使用 XmlDocument.CreateElement 重载，它允许您指定所需的前缀 & ;元素的命名空间，例如

document.CreateElement("x", "ExcelWorkbook", "urn:schemas-microsoft-com:office:excel");

示例

从您的评论中，我认为您已经按照我建议的方式创建了每个元素。我指的是如何让 Excel 特定元素具有正确的命名空间前缀。请参阅下面的示例，了解如何将每个元素与正确的名称空间前缀正确关联：

// store ns in a local variable as it is going to be re-used
const string HTML_NS = "http://www.w3.org/TR/REC-html40";
const string EXCEL_NS = "urn:schemas-microsoft-com:office:excel";

XmlDocument doc = new XmlDocument();
// create the HTML element and set the HTML namespace as the default
XmlElement htmlElement = doc.CreateElement("html", HTML_NS);
// add the office/excel namespaces into the HTML element (so we can reference them later)
htmlElement.SetAttribute("xmlns:o", "urn:schemas-microsoft-com:office:office");
htmlElement.SetAttribute("xmlns:x", EXCEL_NS);
doc.AppendChild(htmlElement);
// associate the HEAD element with the HTML namespace as this is a HTML element
XmlElement headElement = doc.CreateElement("head", HTML_NS);    
htmlElement.AppendChild(headElement);
// now this is the one I am not too sure about as I don't know which 
// namespace you would associate the XML tag with. If you run the code 
// as it is specified here it will write out as <xml xmlns=""> which is
// correct as we aren't associating it with a namespace. As a workaround 
// you could associate it with the HTML NS if it is just for writing out 
XmlElement xmlElement = doc.CreateElement("xml", HTML_NS);   
headElement.AppendChild(xmlElement);
// create ExcelWorkbook element and associate with the excel namespace
// Unlike the HTML/HEAD tags we need to supply the prefix here because the Excel
// namespace is not the default
XmlElement xlWorkbookElement = doc.CreateElement("x", "ExcelWorkbook", EXCEL_NS);
xmlElement.AppendChild(xlWorkbookElement);
// create ExcelWorksheets element and associate with the excel namespace
XmlElement xlWorksheetsElement = doc.CreateElement("x", "ExcelWorksheets", EXCEL_NS);
xlWorkbookElement.AppendChild(xlWorksheetsElement);
// create the ExcelWorksheet element and associate with the excel namespace
XmlElement xlWorksheetElement = doc.CreateElement("x", "ExcelWorksheet", EXCEL_NS);
xlWorksheetsElement.AppendChild(xlWorksheetElement);

希望这能为您解决问题。

Use the XmlDocument.CreateElement overload which allows you to specify the required prefix & namespace of the element e.g.

document.CreateElement("x", "ExcelWorkbook", "urn:schemas-microsoft-com:office:excel");

Example

From your comment I think you have went ahead and create every element in the way I have suggested. What I was referring to was how to get your Excel specific elements to have the correct namespace prefix. See my example below to see how to properly associate each of your elements with the correct namespace prefix:

// store ns in a local variable as it is going to be re-used
const string HTML_NS = "http://www.w3.org/TR/REC-html40";
const string EXCEL_NS = "urn:schemas-microsoft-com:office:excel";

XmlDocument doc = new XmlDocument();
// create the HTML element and set the HTML namespace as the default
XmlElement htmlElement = doc.CreateElement("html", HTML_NS);
// add the office/excel namespaces into the HTML element (so we can reference them later)
htmlElement.SetAttribute("xmlns:o", "urn:schemas-microsoft-com:office:office");
htmlElement.SetAttribute("xmlns:x", EXCEL_NS);
doc.AppendChild(htmlElement);
// associate the HEAD element with the HTML namespace as this is a HTML element
XmlElement headElement = doc.CreateElement("head", HTML_NS);    
htmlElement.AppendChild(headElement);
// now this is the one I am not too sure about as I don't know which 
// namespace you would associate the XML tag with. If you run the code 
// as it is specified here it will write out as <xml xmlns=""> which is
// correct as we aren't associating it with a namespace. As a workaround 
// you could associate it with the HTML NS if it is just for writing out 
XmlElement xmlElement = doc.CreateElement("xml", HTML_NS);   
headElement.AppendChild(xmlElement);
// create ExcelWorkbook element and associate with the excel namespace
// Unlike the HTML/HEAD tags we need to supply the prefix here because the Excel
// namespace is not the default
XmlElement xlWorkbookElement = doc.CreateElement("x", "ExcelWorkbook", EXCEL_NS);
xmlElement.AppendChild(xlWorkbookElement);
// create ExcelWorksheets element and associate with the excel namespace
XmlElement xlWorksheetsElement = doc.CreateElement("x", "ExcelWorksheets", EXCEL_NS);
xlWorkbookElement.AppendChild(xlWorksheetsElement);
// create the ExcelWorksheet element and associate with the excel namespace
XmlElement xlWorksheetElement = doc.CreateElement("x", "ExcelWorksheet", EXCEL_NS);
xlWorksheetsElement.AppendChild(xlWorksheetElement);

Hope that clears things up for you.

使用 CreateElement 的双参数版本，并将您的命名空间指定为第二个参数。例如：

System.Xml.XmlElement myElement = document.CreateElement(
                                      "x:ExcelWorkbook",
                                      "urn:schemas-microsoft-com:office:excel");

Use the two argument version of CreateElement, and specify your namespace as the second argument. For example:

System.Xml.XmlElement myElement = document.CreateElement(
                                      "x:ExcelWorkbook",
                                      "urn:schemas-microsoft-com:office:excel");
