aardio xpath抽取

引入.Net的HtmlAgilityPack库，实现html，xml文档的xpath抽取

import dotNet;

namespace myplu

class xpath{
    ctor( html ){
        this = ..HtmlAgilityPack.HtmlDocument();
        this.LoadHtml(html);    
        this[["select"]] = function(xpath,node){
            node := owner.DocumentNode;
            return node.SelectSingleNode(xpath).OuterHtml;
        };
        this[["selectList"]] = function(xpath,node){
            node := owner.DocumentNode;
            var nodes = node.SelectNodes(xpath); 
            var res = {}; 
            for(i=1;nodes.Count;1){
                ..table.insert(res,nodes[i].OuterHtml); 
            }       
            return res;     
        };  
    };
    /*对象的所有成员必须用分号分隔*/
    
}


namespace xpath

var assembly = ..dotNet.load("HtmlAgilityPack",$"~\lib\myplu\xpath\.res\HtmlAgilityPack.dll");
assembly.import("HtmlAgilityPack");
