LoadFromFile

DocumentElement

XMLDocument1->LoadFromFile(lxml);
_di_IXMLNode snode = XMLDocument1->DocumentElement->ChildNodes->FindNode(aTableName);
if (snode)
{
for (int i = 0; i < snode->ChildNodes->Count; i++)
{
_di_IXMLNode rownode = snode->ChildNodes->Get(i);

String fn = rownode->Attributes["Field"];
}

}
XMLDocument1->Active = false;

增加或修改节点

xml->CreateElement
xml->CreateNode

xml->DocumentElement->AddChild

_di_IXMLNode nodeElement = xml->DocumentElement->ChildNodes->FindNode("DAOPath");
if (nodeElement == NULL)
nodeElement = xml->DocumentElement->AddChild("DAOPath");
nodeElement->Text = DaoPath;

缩进，格式化

XMLDocument1->Options = XMLDocument1->Options << doNodeAutoIndent;

<?xml version="1.0" encoding="utf-8"?>
<data>
<config>
<recent>aaa</recent>
</config>
<list>
<row name="aa" port=""></row>
<row name="bb"  port=""></row>
</list>
</data>

读取recent的值

fangA = XMLDocument1->DocumentElement->ChildNodes->FindNode("config")->ChildNodes->FindNode("recent")->NodeValue;

XMLDocument1->DocumentElement->ChildNodes->FindNode("config")->ChildNodes->FindNode("recent")->NodeValue="newstring";
