Httpagility Pack Scraping Between Broken Tag?

i need to scrape a p tag which has h3 tag after it but does not have a closing p tag. It looks like this :

<script ad>asdasdasd</script>
<p>Translation companies are
-----------------------
-----------------------
<h3 class="this_class">mind blown site</h3>

There is no </p> tag so i cannot parse it completely. Now i have two questions :

1) can this be parsed using httpagility xpath ?

2) i have a function to find text between two strings (getbetween). But i have a doubt - If i use "asdasdasd" and " is it always 100% that vb.net will use the script tag which is just above h3 because there are 2-3 same lines - "asdasdasd"
