(VB.NET UWP/WinRT) HTML Table to CSV

Demonstrates a method for converting an HTML table to a CSV file.

Note: This example requires Chilkat v9.5.0.77 or greater.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.


' First download the HTML containing the table
Dim http As New Chilkat.Http
Dim bdHtml As New Chilkat.BinData

Dim success As Boolean = Await http.QuickGetBdAsync("https://example-code.com/data/etf_table.html",bdHtml)
If (success <> True) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


' Convert to XML.
Dim htx As New Chilkat.HtmlToXml
htx.SetHtmlBd(bdHtml)

Dim sbXml As New Chilkat.StringBuilder
htx.ToXmlSb(sbXml)

Dim xml As New Chilkat.Xml
xml.LoadSb(sbXml,True)

' Remove attributes and sub-trees we don't need.
' (In other words, we're getting rid of clutter...)
Dim numRemoved As Integer = xml.PruneTag("thead")
numRemoved = xml.PruneAttribute("style")
numRemoved = xml.PruneAttribute("class")

' Scrub the element and attribute content.
xml.Scrub("ContentTrimEnds,ContentTrimInside,AttrTrimEnds,AttrTrimInside")

' Let's see what we have...
Debug.WriteLine(xml.GetXml())

' We have the following XML.
' Copy this XML into the online tool at Generate Parsing Code from XML
