我試圖從遠程頁面抓取html表格,並在我的網站上的htmltable中顯示此表格的內容。我正在使用htmlagility包。到目前爲止,這裏是我的代碼:從html中提取表格轉換爲html.net中的htmltable vb(htmlagilitypack)
Imports HtmlAgilityPack
Partial Class ContentGrabExperiment
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'fetch the remote html page
Dim web As New HtmlWeb()
Dim html As HtmlAgilityPack.HtmlDocument = web.Load("http://www.thesite.com/page.html")
'Create table
Dim outputTable As New HtmlTable
Dim tableRow As New HtmlTableRow
Dim tableCell As New HtmlTableCell
'Target the <table> tag
For Each table As HtmlNode In html.DocumentNode.SelectNodes("//table")
'Target the <tr> tags within the table
For Each row As HtmlNode In table.SelectNodes("//tr")
'Target the <td> tags within the <tr> tags
For Each cell As HtmlNode In row.SelectNodes("//td")
'Set the value to that of the <td>
tableCell.InnerText = cell.InnerHtml
'Add the cell to the row
tableRow.Cells.Add(tableCell)
Next
'Add row to the outputTable
outputTable.Rows.Add(tableRow)
Next
Next
'Add the table to the page
PlaceHolderTable.Controls.Add(outputTable)
End Sub
End Class
從此我期待得到充分的表從頁面的innerText,作爲HTMLTABLE,我可以再操作。我得到這個代碼是:
<table>
<tr>
<td>&nbsp;</td>
</tr>
</table>
請有人指出我的錯誤與我的語法。任何幫助非常感謝!
