How can jquery find, count and print to the page, the number of occurrences of `'<lineNo'` that exist inside a div 
called `'dialogue'` and do so without replacing all the text on the page?

```
<div id="dialogue">
<div id="1">
 <lineNo1>1</lineNo1>) 
 <lineNo2>2</lineNo2>) 
 <lineNo3>3</lineNo3>) 
</div>

<div id="2">
 <lineNo1>1</lineNo1>) 
 <lineNo2>2</lineNo2>) 
 <lineNo3>3</lineNo3>) 
</div>
</div>

```

Thank you.
