Operator |
Description |
|
. |
Any single character. Example: h.t matches hat, hit, hot and hut. |
|
[ ] |
Any one of the characters in the brackets, or any of a range of characters separated by a hyphen (-), or a character class operator (see below). Examples: h[aeiou][a-z] matches hat, hip, hit, hop, and hut; [A-Za-z] matches any single letter; x[0-9] matches x0, x1, …, x9. |
|
[^] |
Any characters except for those after the caret "^". Example: h[^u]t matches hat, hit, and hot, but not hut. |
|
^ |
The start of a line (column 1). |
|
$ |
The end of a line (not the line break characters). Use this for restricting matches to characters at the end of a line. Example: end$ only matches "end" when it’s the last word on a line, and ^end only matches "end" when it’s the first word on a line. |
|
\< |
The start of a word. |
|
\> |
The end of a word. |
|
\t |
The tab character. |
|
\xdd |
"dd" is the two-digit hexadecimal code for any character. |
|
\( \) |
Groups a tagged expression to use in replacement expressions. An RE can have up to 9 tagged expressions, numbered according to their order in the RE. The corresponding replacement expression is \x, for x in the range 1-9. Example: If \([a-z]+\) \([a-z]+\) matches "way wrong", \2 \1 would replace it with "wrong way". |
|
* |
Matches zero or more of the preceding characters or expressions. Example: ho*p matches hp, hop and hoop. |
|
? |
Matches zero or one of the preceding characters or expressions. Example: ho?p matches hp, and hop, but not hoop. |
|
+ |
Matches one or more of the preceding characters or expressions. Example: ho+p matches hop, and hoop, but not hp. |
|
\{count\} |
Matches the specified number of the preceding characters or expressions. Example: ho\{2\}p matches hoop, but not hop. |
|
\{min,\} |
Matches at least the specified number of the preceding characters or expressions. Example: ho\{1,\}p matches hop and hoop, but not hp. |
|
\{min,max\} |
Matches between min and max of the preceding characters or expressions. Example: ho\{1,2\}p matches hop and hoop, but not hp or hooop. |
|
\| |
Matches either the expression to its left or its right. Example: hop\|hoop matches hop, or hoop. |

local elemcontent = oid_content($arr[1]);
return $elemcontent
