问题描述

我有解析XML的问题。

I have a problem with parsing XML.

如何获取字段值 se_url 和短语？

我需要获得 link1_1 ， link1_2 ， key1 ， link2_1 ， link2_2 ， key2 ...
，其中 se_url 和短语。

How to get field values se_url and phrase?
I need to get link1_1, link1_2, key1, link2_1, link2_2, key2... which are in se_url and phrase.

我没有在Google中找到如何处理（还没有找到关于如何使用 TXMLDocument ）的手册。

I did not find in Google how to do it (also did not find a manual on how to work with TXMLDocument).

推荐答案

尝试这个：

uses ComObj, MSXML;

procedure TForm1.Button1Click(Sender: TObject);
var
  xml: IXMLDOMDocument;
  node: IXMLDomNode;
  nodes_row, nodes_se: IXMLDomNodeList;
  i, j: Integer;
  url: string;
begin
  // put url or file name
  url := 'http://softez.pp.ua/gg.xml';

  xml := CreateOleObject('Microsoft.XMLDOM') as IXMLDOMDocument;
  xml.async := False;
  xml.load(url); // or use loadXML to load XML document using a supplied string
  if xml.parseError.errorCode <> 0 then
    raise Exception.Create('XML Load error:' + xml.parseError.reason);

  Memo1.Clear;
  nodes_row := xml.selectNodes('/doc/data/row');
  for i := 0 to nodes_row.length - 1 do
  begin
    node := nodes_row.item[i];
    Memo1.Lines.Add('phrase=' + node.selectSingleNode('phrase').text);
    nodes_se := node.selectNodes('search_engines/search_engine/se_url');
    for j := 0 to nodes_se.length - 1 do
    begin
      node := nodes_se.item[j];
      Memo1.Lines.Add('url=' + node.text);
    end;
    Memo1.Lines.Add('--------------');
  end;
end;

结果：

phrase=key1
url=link1_1
url=link1_2
--------------
phrase=key2
url=link2_1
url=link2_2
--------------
