[FOUND ISSUE] iTextSharp Html to PDF - issue parsing html

**lleemon** · Apr 28th, 2009, 10:08 AM

Below I have code that takes a url and pulls the html source. However, using iTextSharp if I print to pdf it works but it shows all the html tags in the document. I want it to be as if viewing in the browser so I believe what I am missing is dealing with the line 'HtmlParser.Parse(document, se)'. Does anyone know how I change this to accept my html code and parse it?

What I am trying to do it make a print to pdf linkbutton on my page that basically will requery the page and send the source to the iTextSharp to convert to pdf. If you think there is a better way let me know.

Code:

Imports System
Imports System.Data
Imports System.IO
Imports System.Xml
Imports iTextSharp.text
Imports iTextSharp.text.pdf
Imports iTextSharp.text.html
Imports iTextSharp.text.html.simpleparser
Imports System.Net

Partial Class testemail
    Inherits System.Web.UI.Page

    Protected Sub btnSendEmail_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnTest.Click
        lblOutput.Text = "ABCDEFG".ToLower
    End Sub

    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim req As WebRequest = WebRequest.Create("http://www.google.com")
        Dim resp As WebResponse = req.GetResponse()

        Dim s As Stream = resp.GetResponseStream()
        Dim sr As StreamReader = New StreamReader(s, Encoding.ASCII)
        Dim doc As String = sr.ReadToEnd()

        CreatePDFDocument(doc)
        
    End Sub

    Public Shared Sub CreatePDFDocument(ByVal strHtml As String)
        Dim MStream As New MemoryStream()
        Dim document As New Document(PageSize.A4, 80, 50, 30, 65)
        Try
            Dim writer As PdfWriter = PdfWriter.GetInstance(document, MStream)
            'document.Open()
            'document.Add(New iTextSharp.text.Paragraph("This is a test and must work"))
            'document.Close()

            Dim se As New StringReader(strHtml)
            document.Open()
            HtmlParser.Parse(document, se)  '<---- DOESN'T LIKE THIS LINE
            document.Close()

        Catch e As Exception
            Throw e
        End Try
        HttpContext.Current.Response.Buffer = True
        HttpContext.Current.Response.ClearContent()
        HttpContext.Current.Response.ClearHeaders()
        HttpContext.Current.Response.ContentType = "application/pdf"
        HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=myPDFNew.pdf")
        HttpContext.Current.Response.BinaryWrite(MStream.GetBuffer())
        HttpContext.Current.Response.End()
    End Sub
End Class
