11. | (Low-level Or)

The low-level or operator | specifies the occurrence of patterns at a position relative to the preceding pattern in the scanned data.

For example:

  "x", ("a" | "b"), "y"

    matches "x", followed by "a" or "b", followed by "y"
    at some position in the scanned data.

Do not confuse the low-level | operator with the high-level OR operator. The high-level OR operator specifies the occurrence of patterns at any positions in the scanned data.
