[英]How can I remove the BOM from XmlTextWriter using C#?
How do remove the BOM from an XML file that is being created? 如何从正在创建的XML文件中删除BOM?
I have tried using the new UTF8Encoding(false) method, but it doesn't work. 我尝试过使用新的UTF8Encoding(false)方法,但它不起作用。 Here is the code I have:
这是我的代码:
XmlDocument xmlDoc = new XmlDocument();
XmlTextWriter xmlWriter = new XmlTextWriter(filename, new UTF8Encoding(false));
xmlWriter.Formatting = Formatting.Indented;
xmlWriter.WriteProcessingInstruction("xml", "version='1.0' encoding='UTF-8'");
xmlWriter.WriteStartElement("items");
xmlWriter.Close();
xmlDoc.Load(filename);
XmlNode root = xmlDoc.DocumentElement;
XmlElement item = xmlDoc.CreateElement("item");
root.AppendChild(item);
XmlElement itemCategory = xmlDoc.CreateElement("category");
XmlText itemCategoryText = xmlDoc.CreateTextNode("test");
item.AppendChild(itemCategory);
itemCategory.AppendChild(itemCategoryText);
xmlDoc.Save(filename);
You're saving the file twice - once with XmlTextWriter
and once with xmlDoc.Save
. 您将文件保存两次 - 一次使用
XmlTextWriter
,一次使用xmlDoc.Save
。 Saving from the XmlTextWriter
isn't adding a BOM - saving with xmlDoc.Save
is. 从
XmlTextWriter
保存不添加BOM - 使用xmlDoc.Save
保存。
Just save to a TextWriter
instead, so that you can specify the encoding again: 只需保存到
TextWriter
,以便您可以再次指定编码:
using (TextWriter writer = new StreamWriter(filename, false,
new UTF8Encoding(false))
{
xmlDoc.Save(writer);
}
我将XML写入字符串(构建器),然后将该字符串写入文件。
