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.

Html Source Code Doesn't Show Html But In Firebug Inspect Element Html Is There?

Jan 10, 2012

This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.

What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.

Here is the source that I am getting using Firefox's Firebug to inspect the element:

<td>
<input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden">
<img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work">
</td>

[Code]...

Why would the two be showing me two different versions of the HTML?

And how would you be able to grab that source to view in a picturebox using webclient?

Html - VB Basic RegEx - Save Value From An Input Tag In HTML Source Code

Feb 16, 2011

I am trying save a value from an input tag in some HTML source code. The tag looks like so:

<input name="user_status" value="3" />

I have the page source in a variable (pageSourceCode), and need to work out some regex to get the value (3 in this example). I have this so far: [Code] Which works fine most of the time, however this code is used to process source code from multiple sites (that use the same platform), and sometimes there are other attributes included in the input tag, or they are in a different order, eg:

<input class="someclass" type="hidden" value="3" name="user_status" />

I just dont understand regex enough to cope with these situations.

Way To Parse HTML

Nov 29, 2010

Does mshtml work with HttpWebRequest? If so, how do I work with it? I thought of downloading the source code of the page I'm requesting into a richtextbox and do my stuff from there, but it sounds kinda impractical to me since I have to use regex to get the innertext of stuff (or not?).

RegEx - How To Retrieve String Variable From External Source And Parse It

Dec 7, 2011

Part of my project is to retrieve a string variable from an external source (google docs) and parse it. This string represents width and height. I have no problem retrieving, I just need to parse it in to two strings. The string has 4 variations.

Here are examples:
3"x4"
3"hx4"w
3hx4w
3x4

The width is always the first number and the height is always the second. Sometimes, the width and height have decimal points. Any way to parse this into two strings of the numeric values only?

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.
