Also, as reference, this website http://regexr.com/ is really helpful in
explaining what a regex is going to do. Over over each element and it'll
explain what that element means. Click the Explain tab at the bottom for
a written explanation of the whole expression.

You can use a search pattern like this:
'/^ *"?(The|An?) +/i'
This assumes that the quote always comes before the rest of the title.
The question mark after the quote means that there can be zero or one
quote, like the question mark after the An means that there can be a
single "n" or none (both artcles A and An will be found).
In some languages (French) typographical rules may require to have a
space between the quote and the text, in that case you could have
'/^ *"? *(The|An?) +/i'
the asterisk after the space means that there can be zero or more spaces.
The plus after the last space means that there can be one or more spaces
after A, An, The.
In most cases, several regular expressions can be written to match the
exact same strings.
The pattern on the cookbook has a tiny optimization but is harder to
understand for a beginner. In most cases, several regular expressions
can be written to match the exact same strings, you can have fun. :-)

I suspect this is a pretty basic regex question. I have quotation
marks at
the beginning of some of my titles, so I modified the TitleNoArticle
function from the CustomPagelistSortOrderFunctions Cookbook page:
'preg_replace("/^ *((?:The|An?) |\")/i", "", (@$page["title"] ?
$page["title"] : $AsSpacedFunction($name)), 1)';
This works great for discarding the leading quotation marks, but I run
into
a problem when I have *both* a leading quotation mark and an article
(the/a/an) at the beginning of my title, in which case the page gets
alphabetized under the article. I would be really grateful to anyone who
could show me how to modify the function to account for this.
