读解析文件

LoadFromFile

LoadXMLData 读XML字符串

DocumentElement

    _di_IXMLNode snode = XMLDocument1->DocumentElement->ChildNodes->Nodes("row");

__property _di_IXMLNode Nodes[System::OleVariant IndexOrName] = {read=GetNode/*, default*/};

    XMLDocument1->LoadFromFile(lxml);

    _di_IXMLNode snode = XMLDocument1->DocumentElement->ChildNodes->FindNode(aTableName);

    if (snode)

    {

        for (int i = ; 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";

 XmlDocument1.DocumentElement.ChildNodes[0];

Node := XmlDocument1.DocumentElement.ChildNodes[0]; // <Class> node

Node.ChildNodes.Add(LoadXMLData('<Property Name="Version" RttiType="tkString"></Property>').DocumentElement);

Node.ChildNodes.Add(LoadXMLData('<Property Name="ShowSubunit" RttiType="tkBoolean"></Property>').DocumentElement);

xml.DocumentElement.ChildNodes.FindNode('data').DOMNode.ownerDocument.importNode()

IDOMDocument
    xml.DOMDocument.appendChild()
    xml.DOMDocument.importNode()

  XMLDocument1.DocumentElement.ChildNodes.FindNode('').OwnerDocument.importNode//IXMLDocument没有此方法
  XMLDocument1.DocumentElement.ChildNodes.FindNode('').DOMNode.ownerDocument.importNode()//IDOMDocument有次方法
     node:= XMLDocument1.DocumentElement.ChildNodes.Nodes[i];
     node.ChildNodes.FindNode('nodename')

var
node:IXMLNode;

XMLDocument1.XML.Text;//包含version
XMLDocument1.DocumentElement.Xml//根节点下的字符串
XMLDocument1.DocumentElement.Text

2、读取文件

LoadXMLDocument

Xml.XMLDoc
#include <Xml.XMLIntf.hpp>
IXMLDocument doc:=LoadXMLDocument('abc.xml');

_di_IXMLDocument doc=LoadXMLData("xmlstring");


_di_IXMLDocument doc=LoadXMLDocument("aa.xml");
doc->DocumentElement->ChildNodes->FindNode("jgbm")->NodeValue;
doc->DocumentElement->ChildNodes->FindNode("para")->Attributes["pw"];

官方的解释是会自动释放！这样就不用创建控件了。TXMLDocument

 http://docwiki.embarcadero.com/RADStudio/Berlin/en/XML_Support_Routines
http://docwiki.embarcadero.com/Libraries/Berlin/en/Xml.XMLDoc.LoadXMLDocument

Returns the interface for an XML document given the name of an XML file.

Call LoadXMLDocument to load an XML document from a file on disk and obtain its interface. LoadXMLDocument creates a new TXMLDocument object and uses it to parse the file specified by the FileName parameter. The TXMLDocument component is not given an owner, which means that it behaves like an interfaced object. When the application releases the interface that LoadXMLDocument returns, the TXMLDocument instance is automatically freed.

解析C++builder工程文件

原始工程文件首行是<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

改成<Project>才能用selectSingleNode方法解析。

procedure TForm2.Button1Click(Sender: TObject);

var

  path: string;

  Xml: IXMLDocument;

  noderef: IXMLDOMNodeRef;

  Root: IXMLDOMNode;

  Node: IXMLDOMNode;

  ConditionStr: string;

  list: TStringList;

begin

  list := TStringList.Create;

  list.LoadFromFile('E:\test\tt.cbproj');

  list.Strings[] := '<Project>';

  Xml := LoadXMLData(list.Text);

  noderef := Xml.DocumentElement.DOMNode as IXMLDOMNodeRef;

  Root := noderef.GetXMLDOMNode;

  path := 'PropertyGroup[@Condition="''$(Cfg_1_Win32)''!=''''"]/FinalOutputDir';

  Node := Root.selectSingleNode(path);

  if not Assigned(Node) then

    self.Caption := 'not not '

不用findNode的写法

Xml.DocumentElement.ChildNodes['makeCard'].ChildNodes['sfzCard'].NodeValue

遍历节点

          s2=    XMLDocument1->DocumentElement->ChildNodes->Get(i)->Text;
}

ShowMessage(Node.Attributes.getnameditem('title').Text); // title2 Node.Attributes.getnameditem('title').Text:='hello'; // <Item name="name2" title="title2"/> => <Item name="name2" title="hello"/>
XMLDocument1.SaveToFile('test.xml');

C# 保存时：
dtXML.WriteXmlSchema("d://sampleSchema.xml");
dtXML.WriteXml("d://sample.xml");
读取时：
dtXML.ReadXmlSchema("d://sampleSchema.xml");
dtXML.ReadXml("d://sample.xml");

DataSet dataSet = new DataSet();

DataTable dataTable = new DataTable();

dataSet.Tables.Add(dataTable);

dataSet.WriteXml("123.xml");

dataSet.ReadXml("123.xml");

DataTable dataTable = dataSet.Tables[0];

DataTable dt = new DataTable();
dt.ReadXmlSchema("aschema.xml");
dt.ReadXml("testout.txt");

DataView dv = dt.DefaultView;
dv.RowFilter = "BKA265='未对应'";

//1.过滤后直接获取DataTable
DataTable newTable1 = dv.ToTable();

this.dataGridView1.DataSource = newTable1;

有了这个Schema，解析xml太牛了

xml数据文件，就直接到数据集了databable

对象转换为XML,类转换为XML

智能是class,因为record不支持这种rtti的反射。record用json的序列化是支持的，没时间研究官方的序列化怎么做到支持record的；

TRttiField是字段，public里定义的就是字段能获取到。
TRttiProperty是属性，要在published里定义才能获取到。
不过这已经很方便了，对象转xml。

 function obj2xml(rootName:string;obj:TObject):string;

var

  xmldcoc: IXMLDocument;

  pNode: IXMLNode;

  t: TRttiType;

  // p: TRttiProperty;

  f: TRttiField;

  r: TValue;

begin

  t := TRttiContext.Create.GetType(obj.ClassType );

  xmldcoc := NewXMLDocument('');

  pNode := xmldcoc.AddChild(rootName);

  for f in t.GetFields do

    pNode.AddChild(f.name).Text := f.GetValue(obj).ToString;

  result := xmldcoc.Xml.Text;

end;

调用代码

procedure TForm1.Button15Click(Sender: TObject);

var

obj:tperson;

begin

  obj := tperson.Create();

  obj.name := '张飞';

  obj.age := ;

  obj.sex := '男';

self.Memo1.Text:= obj2xml('request',obj);
