1. Special symbol input in XML;
& Lt; <less
& Gt;> greater
& Amp; & and number
& Apos; 'single quotes
& Quot; "quotation marks
2. Read XML files (load XML)
Xmldocument Doc = new xmldocument ();
Doc. Load (file. openread (server. mappath ("textread1.xml ")));
3. Save XML
Doc. saveas (server. mappath ("Doc. xml "));
Doc. Save ("Doc. xml ");

4. Get the node Value
Doc. selectsinglenode ("PNET/data/domatter"). childnodes [0]. attributes [0]. value;
Doc. selectsinglenode ("PNET/data/domatter"). Attributes. getnameditem ("value1"). value;
}
Doc. selectsinglenode ("PNET/data/domatter"). Attributes. getnameditem ("name"). value;
5. add nodes and set node values
Xmlnode node = Doc. selectsinglenode ("Node ");
Xmlelement newnode = Doc. createelement ("newnode ");
Node. appendchild (newnode );

Newnode. setattribute ("name", (string) value );
6. Modify node values
Xmlnode node = Doc. selectsinglenode ("data ");
Xmlelement Xe = (xmlelement) node;
If (Xe. getattribute ("name") = value)
Xe. setattribute ("value1", (string) newvalue );

If (Xe. Name = "value ")
Xe. innertext = newvalue;

7. delete a subnode
Xe. removeattribute ("name"); delete an attribute named name
Xe. removeall (); Delete all content in the node

8. Traverse subnodes
Foreach (xmlnode Xn in DOC ){
Xmlelement Xe = (xmlelement) xn;

}
Xmlnodelist xnl = Xe. childnodes;
Foreach (xmlnode xnn in xnl ){
Xmlelement xee = (xmlelement) xnn;

}

XML can be seen as a web page, and XSL can be seen as a CSS style table, but it must be accurate to every element.
