How to extract the string from certain character using javascript?

Question

Hi i am new to programming. i want to extract string from particular character.

Consider the below string.

'<sometext id="2" name="username"/>hello'

I want to retrieve the "username" and text after /> which is "hello"

so basically i have this string as a value for an object property so something like

object  = {
              property_1: "<sometext id=\"2\" name=\"username\"/>hello",
          }

so i retrieve it using object.string_to_parse and store it in variable string_to_parse

let string_to_parse = object.property_1;

Now i want to get the string "username" from string_to_parse and store it in a separate variable and string "hello" from string_to_parse and store it in another variable.

How can i do it. could someone help me with this. thanks.

Answer 1

One potential solution to use here would be to split that string up and store the parts you need. Like such:

 let object = { property_1: "<sometext id='2' name='username'/>hello", }; let string_to_parse = object.property_1; let prop1; let prop2; prop1 = string_to_parse.split("name='")[1].split("'/")[0]; prop2 = string_to_parse.split('/>')[1]; console.log(prop1); console.log(prop2);

Answer 2

Regex should do the trick:

var str = '<sometext id="2" name="username"/>hello';

var re = /name="([^"]*)"/g
match = re.exec(str);
var uname = match[1];

var re = /\/>(.*)$/g
match = re.exec(str);
var msg = match[1];

The uname and msg variables have what you are trying to extract

Depends if you have only one or multiple ones of your separator "/>" . if we suppose we only have one you can get it with:

object.property_1.split("/>")[1] 

The split method helps you return 2 elements, one containing the string before the separator (here ">" ) and one containing the string after the separator.

Using this method you can easily get your username string, so I'll let you do this one yourself.
