主题：[求助]能否抓取网页隐藏在源码中的文字？

我抓取东方财富“千股千评”网页表格数据，网址：http://data.eastmoney.com/stockcomment/

应用代码

Dim web As new System.Windows.Forms.WebBrowser

web.Navigate("http://data.eastmoney.com/stockcomment/")

Do Until web.ReadyState = 4

    Application.DoEvents

Loop

Dim pg = web.Document.GetElementById("gopage")

pg.SetAttribute("Value", "1")

For Each a As object In web.Document.GetElementById("PageCont").GetElementsByTagName("a")

    If a.GetAttribute("ClassName") = "btn_link" Then

        a.InvokeMember("click")

        Exit For

    End If

Next

Do Until web.Document.GetElementById("PageCont").GetElementsByTagName("span")(0).InnerText = 1

    Application.DoEvents

Loop

Dim trs = web.Document.GetElementById("dt_1").GetElementsByTagName("tr")

For i As Integer = 1 To trs.count - 1

    Dim tds = trs(i).GetElementsByTagName("td")

    For j As Integer = 0 To tds.count - 1

        output.show(tds(j).innerText)

    Next

Next

如愿获得表格数据，但检查网页源码时发现有一部分文字隐藏在源码中不在网页中显示出来，如图：

此主题相关图片如下：qq截图2016.png

我想获取如图，以下文字中的红色文字部分，能实现吗？

600000,浦发银行,1,停牌,-,-,-,6.95,18.15,46.34","600004,白云机场,1,走势形态良好‚建议介入。,12.69,2.84%,0.46,11.75,12.59,15.54","600005,武钢股份,1,横向整理‚不跟为主。,2.81,3.69%,0.43,-,2.79,25.69","600006,东风汽车,1,继续震荡格局‚不入为宜。,6.05,4.31%,1.26,27.33,5.98,16.37","600007,中国国贸,1,强势特征明显‚跟进为主。,14.49,3.06%,0.28,23.63,14.44,11.42","600008,首创股份,1,震荡盘整态势‚观望。,7.25,4.32%,0.73,53.78,7.18,15.36","600009,上海机场,1,仍有上行空间‚近期加仓。…………

不可以

要换一种方法处理，红色代码自己变通

 

Dim url As String = "http://data.eastmoney.com/stockcomment/"

Dim rqst As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create(url)

Dim rsps As System.Net.HttpWebResponse = rqst.GetResponse

Dim stm As System.IO.Stream = rsps.GetResponseStream()

Dim reader As New System.IO.StreamReader(stm, EnCoding.Default)

Dim str As String = reader.ReadToEnd

rsps.Close
stm.Close
reader.close

Dim s1 As String = "defjson:{data:"
Dim s2 As String = "param: {"
Dim idx1 As Integer = str.indexof(s1) + s1.length
Dim idx2 As Integer = str.indexof(s2)
str = str.substring(idx1+1, idx2-idx1)
msgbox(str)

Dim ary() As String = str.split(",")
For i As Integer = 0 To ary.length-1
    output.show(i & "  " & ary(i))
Next

这种方法能换页吗？

呃，不能......

换一种方法

 

Dim web As new System.Windows.Forms.WebBrowser

web.Navigate("http://data.eastmoney.com/stockcomment/")

Do Until web.ReadyState = 4
    Application.DoEvents
Loop

Dim sr As new IO.StreamReader(web.DocumentStream, Encoding.GetEncoding( web.Document.Encoding))
Dim str As String = sr.ReadToEnd()

Dim s1 As String = "defjson:{data:"
Dim s2 As String = "param: {"
Dim idx1 As Integer = str.indexof(s1) + s1.length
Dim idx2 As Integer = str.indexof(s2)
str = str.substring(idx1+1, idx2-idx1)
msgbox(str)

Dim ary() As String = str.split(",")
For i As Integer = 0 To ary.length-1
    output.show(i & "  " & ary(i))
Next
