carriage return on windows

bryson

I'm actually using perl, but php can use perl syntax for regex... and not having any luck on the perl forums

I'm trying to account for possible carriage returns in a file.
I'm looking for: <meta name="author" content="John Doe">
But sometimes there's extra spaces by accident or even a carriage return
This works fine for extra spaces:
/<meta name="author" content="[azAZ '-]?">/is

and this works fine for only carriage returns:
/<meta (\r|\n)name="author" (\r|\n)content="[azAZ '-]?">/is

and this works fine if there's only one or the other:
/<meta (\r|\n)name="author" (\r|\n)content="[azAZ '-]?">/is

but if there's spaces and carriage returns it doesn't work.
Oh, maybe it's (\r\n) without the or???

*note, i'm running my perl script against local files on a windows 2000 box, not Unix/Linux.

How about:

/<meta[\s\r\n]+name="author"[\s\r\n]+content="[azAZ '-]?">/is

hmmm
* Match 0 or more times
+ Match 1 or more times

there's always gonna be 1 space, but there may not be a carriage return
So i need the + for whitespace and * for carriage returns i guess so maybe
square brackets are only for ranges i thought?
So maybe:

/<meta(\s)+(\r\n)name="author"(\s)+(\r\n)content="[azAZ '-]*">/is

oh btw, i'm using a slurp... so the whole file is one string

Square brackets define a character class: it matches on any of the characters within it (and can include ranges of characgters). "\s" is any whitespace character. Thus, [\s\r\n]+ matches 1 or more of any combination of whitespace characters and/or carriage returns and/or newlines.
