Perhaps it was the string size which has multiple quotes and is not all
escaped. Sean DeNigris writes about an interesting trick to preserve all the
quotation marks inside long strings, especially html-strings. See this post
from Sean for this trick http://seandenigris.com/blog/?p=647.



This code returns the OrderedCollection as expected by you.


source := htmltext678 contents.
aString := '<a href="billionaires08_(.*)html">(.*).</a></td>'.
matcher := RxMatcher forString: aString.
matcher matchesIn: source.
"Transcript show: (matcher matchesIn: source); cr."



The htmltext678 is the TextMorph where I stored your html page and extracted
the contents to preserve all inline quotes. I took a shorter match-string
(aString).

One thing i noticed in the referred code that there was an ordered
collection being created which wasn't doing anything.
