Extract HTML tags from String using Regular Expression

[gorgered]

Hi,

I am very new to regular expressions and I need some of your help.

String htmlString = "The values for Key1 is <span id=\"key1\">value1</span> and for Key2 is <span id=\"key2\">Value2</span>.";

Output form the reg exp should be the html tags.

key1:value1
key2:value2

I looked at the jakarta-oro and it looks good but as I said I am just a starter.

Thanks
Gorge
