This effect is mainly to focus on the performance of search keywords.1. Single keyword matchIf just match the search content can be written simple, the code is as follows:if (name = null name.contains (Mkeyword)) { int index = Name.indexof (Mkeyword); int len = Mkeyword.length (); spanned temp = html.fromhtml (name.substring (0, index) + "The above name is the one you want to display the entire item content, Mkeyword is the keyword of

When working with strings in the foreground, it is sometimes not necessary to dynamically stitch strings, and a certain part of the string may be fixed, so we can use regular expressions to match HTML elements in the development process. As follows:var html = (function() {/* */} in Div. ToString (). Match (/[^]*\/\* ([^]*) \*\/\}$/) [1];The HTML is written as a comment in parentheses, the entire string is matched by the match method, and the result is as follows:The returned result is exactly

On the positive I was a smattering, I am the idea of the regular is, can be used on the line!
For all the characters, my first understanding was. *
Then Google a bit, just know. * Connecting together means any number of characters that do not contain a newline.
So you can use [\s\s]* it means any whitespace character and non-white-space character. Similarly, you can use [\d\d]*], [\w\w]*] to express. D and D,w and W,s and S are all antisense and add up to all the characters.
Note: The n writ

When using match it, if no global flag (g) is set, the 0 elements of the array contain the entire match, and the 1th to n element packageContains any substring matches that have occurred in the match. This is equivalent to an Exec method that does not have a global flag set. If you set the globalFlag, Element 0 to n contains all matches.Match a slash with one or more slashesvar results=m.match (New RegExp ("///+", "GI"));Match number one or morevar re
To use a regular expression to get any character in a paragraph of text, write the following matching rule:
(.*)
After the results are run, the text after the wrapping cannot be obtained. Then I looked up the manual and found the regular expression, "." (dot notation) matches all characters except the newline character "\ n".
The following are the correct regular expression matching rules:
([\s\s]*)
It can also be represented by "([\d\d]*)", "([\w\w
HTML tags have the following special features:
1. If there is a property, then it must have a space before.
2. The closing angle brackets must be preceded by double quotes, or double quotes with a few spaces
Based on these two features, I wrote a regular expression of the most painful HTML tags as follows:
The code is as follows
Copy Code

The second question mark means that the greedy pattern finds the closing bracket to stop,
