A list of wildcard characters:

*: Any character of any length

650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M00/6C/05/wKiom1U9wCOg8RQjAABrP4V2vVE382.jpg "title=" 11.jpg "alt=" Wkiom1u9wcog8rqjaabrp4v2vve382.jpg "/>

?: any single character

650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M01/6C/05/wKiom1U9wK_BcaAiAAC6fH1lvmo870.jpg "title=" 12.jpg "alt=" Wkiom1u9wk_bcaaiaac6fh1lvmo870.jpg "/>

Note: Represents any single character, so the abc,acc,a98c here cannot match.

[]: matches any single character within the specified range, commonly used [a-z],[0-9],[a-z]

650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M00/6C/01/wKioL1U9wuLz4yxJAACg0D4zrOM171.jpg "title=" 13.jpg "alt=" Wkiol1u9wulz4yxjaacg0d4zrom171.jpg "/>

[^]: Configures any single character outside the specified range, similar to the inverse

650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M01/6C/05/wKiom1U9wjbgPZIQAAC0jnMh2uc769.jpg "title=" 14.jpg "alt=" Wkiom1u9wjbgpziqaac0jnmh2uc769.jpg "/>

Note: [^a-z]: As long as it is not lowercase letters are counted. Matches a single character, so the match is "a98c"

Common character sets: All match only a single

[: Space:]: all whitespace characters

[:p UNCT:]: All punctuation

[: Lower:]: All lowercase letters

[: Upper:]: So capital letters

[:d Igit:]: All sets of numbers

[: Alnum:]: So letters and numbers

[: Alpha:]: So the alphabet

The above example can be changed to:
