如何创建 xmlns:xsi 但没有前缀的根节点?
How to create root node with xmlns:xsi but no prefix?
创建没有前缀但显示xmlns:xsi="blah"
的根节点的正确方法是什么?基本上我想要这样的东西:
<EDSCrate xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="EDS_Crate_2010-02-10.xsd" version="0.95">
<Whatever>
</Whatever>
</EDSCrate>
然而,我已经尝试了很多方法,它就是不会给我一个没有命名空间的简单节点,即使有,它也没有在属性中给我正确的 xmlns:xsi
.
我想避免任何黑客攻击,例如覆盖 ToString
和自己替换 XmlWriter
中的文本。
string uri = "http://www.w3.org/2001/XMLSchema-instance";
XmlDocument doc = new XmlDocument();
doc.PreserveWhitespace = true;
doc.AppendChild(doc.CreateXmlDeclaration("1.0", "UTF-8", null));
nsmgr = new XmlNamespaceManager(doc.NameTable);
nsmgr.AddNamespace("xsi", uri);
XmlElement root = doc.CreateElement("EDSCrate", uri);
// at this point, it already added xmlns="http://www.w3.org/2001/XMLSchema-instance" without me doing anything
root.RemoveAllAttributes();
// but i want xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"!!
root.SetAttribute("xmlns:xsi", uri);
root.SetAttribute("xsi:noNamespaceSchemaLocation", "EDS_Crate_2010-02-10.xsd");
我发现使用 Linq2Xml 更容易。
XNamespace xsi = "http://www.w3.org/2001/XMLSchema-instance";
var xdoc = new XDocument(
new XElement(
"EDSCrate",
new XAttribute(XNamespace.Xmlns + "xsi", xsi),
new XAttribute(xsi + "noNamespaceSchemaLocation", "EDS_Crate_2010-02-10.xsd"),
new XAttribute("version", "0.95"),
new XElement("Whatever","")
)
);
var xml = xdoc.ToString();
输出:
<EDSCrate xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="EDS_Crate_2010-02-10.xsd"
version="0.95">
<Whatever></Whatever>
</EDSCrate>
string uri = "http://www.w3.org/2001/XMLSchema-instance";
var doc = new XmlDocument();
doc.AppendChild(doc.CreateXmlDeclaration("1.0", "UTF-8", null));
var root = doc.CreateElement("EDSCrate");
doc.AppendChild(root);
root.AppendChild(doc.CreateElement("Whatever"));
var attr = doc.CreateAttribute("xsi", "noNamespaceSchemaLocation", uri);
attr.InnerText = "EDS_Crate_2010-02-10.xsd";
root.SetAttributeNode(attr);
root.SetAttribute("version", "0.95");
