A regex will work, but xpath expression is better in general, or you
could write an xpath expression with some regex
http://www.regular-expressions.info/xpath.html
which is probably better if you are going to use regex at all.
Using Gordon's xpath exp the js to get your earthworm count should be
like:
var ew=document.evaluate("//p[contains(.,'earthworms')]/
strong",document,null,9,null).singleNodeValue;
if(!ew) return;// no earthworms node found
ew=ew.innerHTML*1;
alert("Number of earthworms is "+ew);
Where the last line that alerts the earthworm count is something more
useful.
