Hi

I'm writing a little app and I need some html parsing through regular
expressions.

I wrote this piexe of code

Private Function findImgTags(ByVal strHTML As String) As Object
    dim MatchObj As Match = Regex.Match(strHTML, "<img[^>]*>",
RegexOptions.IgnoreCase)
    return MatchObj
End Function

This should return an object containing all the img tags, unfortunately
returns only the first img :(

Plus, I need to parse the whole html and find retain only thos img that
contains the string 'edit', as for example:

<img src="myimage.gif" title="edit" border="0">

How can I manage to do this?

Thanks in advance

Use 'Regex.Matches' instead of 'Regex.Match'.

Show quoteHide quoteok, this should return an array of matches, right?
So this solves the first question.

But, how can I retrieve only those img tag containing the 'edit' string?
I know this is more a matter of reg_exp, but hope someone can help :)

Thanks

Can you post a couple of lines?

a couple of lines of what? Of VB code? of html code?

well, as for VB, here you go:

Private Function findImgTags(ByVal strHTML As String) As Object
  'Returns the img tag we are searching
   Dim Match = Regex.Matches(strHTML, "<img[^>]*>", RegexOptions.IgnoreCase)
   Dim str As Object
   Dim a As String
   For Each str In Match
       a = str.ToString()
       If InStr(a, "edit", CompareMethod.Text) Then Return a
   Next
   Return False
End Function

while if you meant html code, well imagine an html page with a serie of
images, like this:

<img src="image1.gif" title="join">
<img src="image1.gif" title="leave">
<img src="image1.gif" title="add">
<img src="image1.gif" title="edit">
<img src="image1.gif" title="delete">

I would like to retrieve just the last one. As you can see, I retrieve
all the images, and then do a loop on the object to find the right one.
But I know I can avoid this with the proper regular expression.
The question is: how can I do?

Thanks a lot

To match

<img src="image1.gif" title="delete">

anywhere in the line you need something like

\<img src=[^>]* title=\"delete\"\>

Can't say this is exactly right but it should be close.
