我目前正在尝试从HTML文档中解析DIV中的特定表格。
我有这个工作窗口Silverlight,但WP7 HTML敏捷包似乎是一个完全不同的东西。
HTML看起来像这样
<div id="FlightInfo_FlightInfoUpdatePanel">
<table cellspacing="0" cellpadding="0"><tbody>
<tr class="">
<td class="airline"><img src="/images/airline logos/NZ.gif" title="AIR NEW ZEALAND LIMITED. " alt="AIR NEW ZEALAND LIMITED. " /></td>
<td class="flight">NZ8</td>
<td class="codeshare"> </td>
<td class="origin">San Francisco</td>
<td class="date">01 Sep</td>
<td class="time">17:15</td>
<td class="est">18:00</td>
<td class="status">DEPARTED</td>
</tr>
我目前正在使用此代码解析“FlightInfo_FlightInfoUpdatePanel”DIV Box中的表格
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
using HtmlAgilityPack;
namespace Auckland_Airport
{
public partial class MainPage : PhoneApplicationPage
{
// Constructor
public MainPage()
{
InitializeComponent();
}
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
var doc = new HtmlDocument();
doc.LoadHtml("http://www.SourceURL");
var flightTableCell = doc.DocumentNode.Descendants("div")
.FirstOrDefault(x => x.ID = "FlightInfo_FlightInfoUpdatePanel")
.Element("table")
.Element("tbody")
.Elements("td")
.FirstOrDefault(x => x.Attributes.Contains("flight"));
var value = flightTableCell.InnerText;
这会产生未处理的异常错误:
MainPage.PhoneApplicationPage_Loaded(Object sender, RoutedEventArgs e)
at MS.Internal.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args)
at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, String eventName)
答案 0 :(得分:0)
尝试这样的事情:
var flightTableCell =
doc.DocumentNode
.Descendants("div")
.FirstOrDefault(x => x.Id == "FlightInfo_FlightInfoUpdatePanel")
.Element("table")
.Element("tbody")
.Elements("td")
.FirstOrDefault(x => x.Attributes.Contains("flight"));
var value = flightTableCell.InnerText;
this.textBlock1.Text = value;
由于您无法使用xpath,因此您不得不手动遍历DOM。
