Android Question Regex.Matcher Issue

[hyokim07]

Hi, Erel!
I am trying to download image from the web with the following input:
<div class="img"><img id="imgid48" src="image/Kim_Hyo.jpg" alt="Kim_Hyo" width="220" height="220" onClick="toggleIt('id48a')"><div class="desc" id="name48">Kim Hyo</div><div class="desc" id="id48a">?</div></div>

I am trying to use Regex.Matcher. I am lost. Can you please help me?
Thank you very much in advance.

OK, I will be careful next time.
I just want read the pattern of image names. So I can download image images with the different names from the same source.
Thank you in advance.

Something like:

Dim m As Matcher = Regex.Matcher("src=\""([^""]+)\""", text)
   Do While m.Find
     Log(m.Group(1))
   Loop

Thank you, Erel!
I've tried with the following to be able to distinguish with other image files:
Dim m As Matcher = Regex.Matcher(""\"" src=\""([^""]+)\""", text)
Do While m.Find
Log(m.Group(1))
Loop

The results were:
js/floating.js
image/Kim_Hyo.jpg

I just need to get the image file name.

The html file has a several images with different img id.
Is there any way that can extract the bold and underlined one from the below html codes?
<div class="img"><img id="imgid48" src="image/Kim_Hyo.jpg" alt="Kim_Hyo" width="220" height="220" onClick="toggleIt('id48a')"><div class="desc" id="name48">Kim Hyo</div><div class="desc" id="id48a">?</div></div>

<script type="text/javascript" src="js/floating.js"></script>


My desired result should be:
image/Kim_Hyo.jpg

I hope this is not confusing.
Thank you in advance.

Is it YOUR website you want to get the images from or is it an source from domeone other?
If it is yours; you can restructure your html to the desired order inside the img-tag.

If it is from another; you should find the right RegEx for HIS img-tag-propertiers-order.

That´s the problem. You cannot RegEx a Website, you have to use an DOM-Parser...

If it is your website then you also could do that with JavaScript and, if the website is loaded from within a webview with javascript-interface, post the results from Javascript to your App.

With JQuery for ex it should be only a few lines of code...

$('img').each(function(){
var t=$(this);
alert(t.attr('src')); // src
});

Please see this example from warwound telling how to inject javascript into a webpage which is loaded in a webview..

Thank you very much.
I cheated by using the following code and it worked.
Do While m.Find
If (m.Group(1).IndexOf("image")>-1) Then
links.Add(m.Group(1))
End If
Loop
Thanks for all the help.
