XElement 命名空间(如何?) [英] XElement namespaces (How to?)
问题描述
如何创建带有节点前缀的 xml 文档,例如:
How to create xml document with node prefix like:
<sphinx:docset>
<sphinx:schema>
<sphinx:field name="subject"/>
<sphinx:field name="content"/>
<sphinx:attr name="published" type="timestamp"/>
</sphinx:schema>
当我尝试运行类似 new XElement("sphinx:docset")
之类的东西时,我得到了异常
When I try to run something like new XElement("sphinx:docset")
i getting exception
未处理的异常:System.Xml.XmlException:':' 字符,十六进制值ue 0x3A,不能包含在名称中.
在 System.Xml.XmlConvert.VerifyNCName(String name, ExceptionType exceptionType)
在 System.Xml.Linq.XName..ctor(XNamespace ns, String localName)
在 System.Xml.Linq.XNamespace.GetName(String localName)
在 System.Xml.Linq.XName.Get(String ExpandedName)
Unhandled Exception: System.Xml.XmlException: The ':' character, hexadecimal val ue 0x3A, cannot be included in a name.
at System.Xml.XmlConvert.VerifyNCName(String name, ExceptionType exceptionTyp e)
at System.Xml.Linq.XName..ctor(XNamespace ns, String localName)
at System.Xml.Linq.XNamespace.GetName(String localName)
at System.Xml.Linq.XName.Get(String expandedName)
推荐答案
LINQ to XML 真的很简单:
It's really easy in LINQ to XML:
XNamespace ns = "sphinx";
XElement element = new XElement(ns + "docset");
或者使别名"正常工作以使其看起来像您的示例,如下所示:
Or to make the "alias" work properly to make it look like your examples, something like this:
XNamespace ns = "http://url/for/sphinx";
XElement element = new XElement("container",
new XAttribute(XNamespace.Xmlns + "sphinx", ns),
new XElement(ns + "docset",
new XElement(ns + "schema"),
new XElement(ns + "field", new XAttribute("name", "subject")),
new XElement(ns + "field", new XAttribute("name", "content")),
new XElement(ns + "attr",
new XAttribute("name", "published"),
new XAttribute("type", "timestamp"))));
产生:
<container xmlns:sphinx="http://url/for/sphinx">
<sphinx:docset>
<sphinx:schema />
<sphinx:field name="subject" />
<sphinx:field name="content" />
<sphinx:attr name="published" type="timestamp" />
</sphinx:docset>
</container>
