此代码来自msdn c#
service cloud.firestore {
match /databases/{database}/documents {
match /cats/{catId} {
allow read;
allow update, create, write, delete: if resource.data.ownerId == request.auth.uid;
}
}
}
输出:
writer.WriteStartElement("root");
writer.WriteAttributeString("xmlns", "x", null, "urn:1");
writer.WriteStartElement("item", "urn:1");
writer.WriteEndElement();
writer.WriteStartElement("item", "urn:1");
writer.WriteEndElement();
writer.WriteEndElement();
在这里我得到的错误是错误,它不是在创建我的xml
<root xmlns:x="urn:1">
<x:item/>
<x:item/>
</root>
但是当我尝试这样做时,我可以生成<< strong> xhtml:link 元素但对Google来说这无效:
writer.WriteAttributeString("xmlns", "xhtml", null, "http://www.w3.org/1999/xhtml");
writer.WriteStartElement("link", "http://www.w3.org/1999/xhtml");
区别只是URL的端上的 SLASH (/)
