According to my understanding, XSLT is responsible for displaying data stored in XML files. The Style and style displayed by the results of the same XML file combined with different XSLT can be quite different.
It may also be because of its powerful functions. XSLT has many syntaxes and functions, bu
2=rtrim ($STR);echo "Executes the length after RTrim ():". strlen ($str 2). "";$str 3=trim ($STR);echo "The length after the trim () is performed:". strlen ($str 3). "";echo "Remove the string after the trailing space: [". $str 3. "]";?>
Summary: The same problem will have a variety of solutions, as we delete the word spaces, you can use two different methods to achieve the desired effect.

This article mainly introduces two methods for removing spaces at the beginning and end of php. This article provides two methods, preg_replace and trim functions, and provides examples, if you need a friend, you can refer to the seemingly simple question. In fact, it is still a bit pitfall. First of all, space escape is not a string. trim () cannot be used directly.
1. Replace with preg_replace
The Code is as follows:

In other programming languages, Functions LTrim and RTrim are used to remove spaces and tabs from the beginning and end of a string, respectively. Some also provide the function trim to remove whitespace characters at both ends of the string. Perl does not have these functions because simple regular expression substitutions can do this (although I'm sure Cpan has a lot of modules to implement these functions). In fact it was so simple that it became a
This article describes how to use the trim function in PHP to remove spaces and special characters from the left and right strings, combined with the instance, the trim function does not include additional parameters to remove spaces and the use of additional parameters to remove specified characters is analyzed, for more information about how to use the trim function to remove
: This article describes how to use the trim function in PHP to remove spaces and special characters from the left and right sides of a string. For more information about PHP tutorials, see. This example describes how PHP uses the trim function to remove leading spaces and special characters from strings. We will share this with you for your reference. The details are as follows:
The trim () function in
Removing spaces in js does not allow you to directly use trim to delete the space. It is not as easy as we thought in js, especially the trim function that is less reliable than the code that I want to delete spaces before and after.
The Code is as follows:
Function String. prototype. trim () {return this. replace (/(^/s *) | (/s * $)/g, "");} // remove the Left and Right SpacesFunction String. prototype.

When using git to submit Python source code, the following error occurs: whitespace error: trailing space at end of line. Analyze the source file carefully and find that lines at the end of the source code are indeed spaces. According to the general rule, such a situation should not occur, and it is meaningless. All spaces at the end of the line should be removed

Remove the Space key at the beginning and end of a string (the idea can be extended to other symbols ).
There are two scenarios,
1. the first is the space that can be changed for this string, such as the character array, allocated in the heap (calloc and malloc), and some buffer (transmitted over TCP, however, the above method is also used, but I just
Usually, when the form is validated, the text of the input box needs to be taken out of the string and trailing blanks.The current version of the browser is natively supported by the trim () method, and the previous version of JQ also implements support for the method.Boring time can be concerned about how to achieve, sometimes written interview will also ask, by the way review the regular.

Remove the length of the head and trailing space measurement string*obj parameter: Object with String * Return value: The object after the space is removed * *function Trimspace (obj){String.prototype.Trim = function (){Return This.replace (/(^s*) | ( s*$)/g, "");}Obj.value = Obj.value.Trim ();}/**************************** the length of the string measured *********************************//*** Remove head and tr
Ideas:
Make a note of the position of the first non-empty character temp1, note the number of space_count_head and the number of trailing spaces space_count_tail.
Total number of spaces length_new=space_count_head+space_count_tail;
Copy the original string with the Temp1 as the starting position and the length of length_new to the source string.

Rtrim () function: rtrim ($ str, $ charlist)
$ Str indicates the processed string. $ charlist is a special character to be deleted. if it is null, spaces on the right are removed. the code is as follows:

B are Used before their declarations.To solve this problem, C++11 introduced a feature called trailing return types. Using This feature, the previous program can be rewritten as follows:TemplateAuto Mul (t A, T B), Decltype (a*b) {return a*b;}We Specify the function return type after the declaration of parameter declarations. Composite symbol->decltype (T1+T2) is called a trailing return type. The Auto key
This article mainly introduces Perl delete leading and trailing blanks (remove left and right spaces, white space characters), this article gives a number of methods to achieve this requirement, the need for friends can refer to the following

The first method: a function that comes with PHP
/*
Trim removes a string at both ends of a space,
RTrim is to remove a string to the right of the space,
LTrim is to remove the left space of a string.

Echo Trim ("space"). "
