Hi. It's been many years since programming but I've had an idea for long but never knew how do ask. (I was very young at the time.)

Basically, I need a way to search through text and find a part of the text. Let's say it looks like this:

(The text is from a page source)
Code:
<meta property="example:content1" content="123456" />
<meta property="example:content2" content="abcde" />
<meta property="example:content3" content="fghijkl />
<meta property="example:content4" content="mnopq" />
And all I want is the "adcde" put in textbox1 from "example:content2"

I know how to get page source so know I don't need that information. I just need to know how to get the code to look through the text and get "adcde"


Any help would be awesome guys, thank you so much for reading
