Revision as of 05:50, 20 April 2006 edit 129.93.191.176 (talk) Explained why [.\n] doesn't match any character ← Previous edit		Revision as of 06:37, 20 April 2006 edit undo -Barry- (talk \| contribs) 1,472 edits Shortened a table cell that was way too long for such a narrow column in IE and Firefox, and too detailed for a chart. Not sure if effect of modifiers should be mentioned, but I didn't. Next edit →
Line 11: <tr> <td>'''.'''</td> <td>Normally matches any character except a newline. Within square brackets the dot is literal.</td> <td>Matches an arbitrary character, but not a newline. It is important to note that when placed inside square brackets ([.]), the dot becomes a literal period, meaning it will only match the '.' charater. You can confirm this with the expression /[.\n]{5}/, which, at first glance, appears to look for any five characters, new line or otherwise. In truth, it is equivalent to /[\.\n]{5}/. Instead of [.\n], use (.\|\n) or a character class like [\s\S].</td> <td align="left"> <pre>
