我对 XML 和 C# 还很陌生,所以请理解这个问题是否太愚蠢而无法提出。
我正在使用 C# win-form 应用程序转换 XML 格式。该应用程序使用 打开一个 xml 文件OpenFileDialog
,然后将执行转换(这已经完成,但我仍然需要添加或删除一些类似下面的内容)。转换后,应用程序将使用 .xml 保存修改后的 xml 文件SaveFileDialog
。
原始 XML 格式
<?xml version="1.0" encoding="utf-8" ?>
<DataList>
<Data>
<ID>1</ID>
<Name>Mike</Name>
<Age>23</Age>
</Data>
<Data>
<ID>1</ID>
<Name>Mike</Name>
<Age>23</Age>
</Data>
<Data>
<ID>1</ID>
<Name>Mike</Name>
<Age>23</Age>
</Data>
..<Data></Data> continued...
</DataList>
我想编辑 XML 文件如下
<?xml version="1.0" encoding="utf-8" ?> **→ Remove this delaration!**
<MainInterface> **→ Add 'root element' before existing nodes**
<DataList>
<Data>
<ID>1</ID>
<Name>Mike</Name>
<Age>23</Age>
</Data>
<Data>
<ID>1</ID>
<Name>Mike</Name>
<Age>23</Age>
</Data>
<Data>
<ID>1</ID>
<Name>Mike</Name>
<Age>23</Age>
</Data>
..<Data></Data> continued...
</DataList>
</MainInterface> **→ close newly added root element**
我试过下面的代码,但似乎它不起作用
OpenFileDialog openFileDialogue = new OpenFileDialog();
openFileDialog1.DefaultExt = "xml";
openFileDialog1.Filter = "xml files (*.xml)|*.xml";
openFileDialog1.Title = "Select a xml File";
openFileDialog1.ShowDialog();
XDocument xmlFile = XDocument.Load(openFileDialog1.FileName);
**// Remove Declaration**
XDocument doc = new XDocument(new XDeclaration(null, null, null));
**// Add Root Element**
XElement doc1 = XElement.Parse(openFileDialog1.FileName);
XElement root = new XElement("MainInterface", doc1);
//doc.Save(_data)
openFileDialog1.FileName = root.ToString();
-----------------------------------------------------------------------------------
Do something for conversion ~~~
-----------------------------------------------------------------------------------
SaveFileDialog saveFileDialogue1 = new SaveFileDialog();
saveFileDialog1.Filter = "xml File |*.xml";
saveFileDialog1.Title = "Conversion Completed! Save a XML file";
saveFileDialog1.FileName = "XML Converted.xml";
saveFileDialog1.ShowDialog();
xmlFile.Save(saveFileDialog1.FileName);
关键是我不是在创建新的 XML 文件,而是修改现有的 xml 文件以摆脱声明并添加根元素。我应该使用 XML 编写器吗?有没有更简单的方法来做这些?先感谢您。
谢谢您的回答。我发现这对我有用!
SaveFileDialog saveFileDialogue1 = new SaveFileDialog();
saveFileDialog1.Filter = "xml File |*.xml";
saveFileDialog1.Title = "Conversion Completed! Save a XML file";
saveFileDialog1.FileName = "XML Converted.xml";
saveFileDialog1.ShowDialog();
XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
StringWriter sw = new StringWriter();
using (XmlWriter xw = XmlWriter.Create(saveFileDialog1.FileName, settings))
{
xmlFile.Save(xw);
}
string s = sw.ToString();
