c# - 使用 XmlDocument 导出 Excel 表格的 XML

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?

最佳答案

使用 XmlDocument.CreateElement重载允许您指定元素的所需前缀和命名空间,例如

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

示例

根据您的评论,我认为您已经按照我建议的方式创建了每个 元素。我指的是如何让您的 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命名空间前缀正确关联:

// 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);

希望这能帮您解决问题。
