Algorithm process
1. main steps:
Compared with the previous algorithm, this algorithm highlights the following (
Feature-basedTo determine the em
has id and classes at the same time, you must output the id first.
If a tag has more than one class, you must output them by the order according to the input.
For example
"Div. aa # bb. cc. ee> p # g> span. d" =>
"
3. Handle parentheses.
Use parentheses to deal with sibling relation among tags!
For example
Can be obtained by "div. aa # bb. cc. ee> (p # g1> span. d1) (p # g2> span. d2) (p # g3> span. d3 )"

you still remember that ARI is created every time the function is called ?), Correspondingly, g also "created" five times. Before the first setTimeout is reached, the stack contains the following records (I write the g into five records separately ):

| ARI of f; t = 0 bytes ------ static link of g0
| ARI of f; t = 1 bytes ------ static link of g1
| ARI of f; t = 2 bytes ------ static link of g2

you need to use a dynamically generated string as the pattern for matching, you can use this function to escape the special characters that may be contained in it.
If the optional parameter delimiter is provided, the character is also escaped. It can be used to escape the delimiters required by the PCRE function. The most common delimiters are diagonal lines /.
Special characters in a regular expression include:. \ + *? [^] $ () {}=!
Note: This function can be safely used for binary objects.

So this will be the police.Workaround:Add a few more log groups, and each log group is a bit larg

Preg_quote () takes str as the parameter and adds a backslash before each character that belongs to the regular expression syntax. If you need to use a dynamically generated string as the pattern for matching, you can use this function to escape the special characters that may be contained in it.
