VS 2010 Parse A Html File For Image Locations?

Mar 15, 2011

I am using this code to parse an html file for image locations:

Dim htmlDoc As String = IO.File.ReadAllText(path, System.Text.Encoding.Default)
Dim Regex As New System.Text.RegularExpressions.Regex("img.*srcs*=s*(?:""(?<1>[^""]*)""|(?<1>S+))")

[Code].....

How would I change the regex string so that it leaves off everthing from the img to the src=, so that I'm just left with what's in between the quotes? Note that sometimes there is stuff between "img" and "src=" and sometimes there is not.

Regex To Parse HTML Tables

Dec 19, 2010

I am trying to remove the tables within an HTML file, specifically, for the following document, I'd like to remove anything within the tags <TABLE....> and </TABLE>. The document contains multiple tables with texts in between.

The expression that I came up with, <TABLE.*>s*[s|S]*</TABLE>s*, however would remove the text in between the tables. In fact it would remove everything between the first <TABLE> and the last </TABLE> tags. I would like to keep the texts in between and only remove the tables.

Retrieve URL And Then Parse The HTML From The Page?

Mar 27, 2009

I'm using the following code to retrieve a URL and then parse the HTML from the page:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click
Dim Temp As String, searchstr As String

[Code]....

I think my problem is that I don't exactly understand how I am supposed to start and end the parsing. I know that in my above code, the "meta" tag is the start and the chr(34), double quotes, is the ending.

When I modify my code, I have price line, which in th html ends with another character, the ">" sign. In the first code, the "content" tag doesn't end with another character, it just continues the line, which is easy and it works.
