How to set a regular expression to find pieces of text with text?

Question

Regular Expressions

Hello.
It seems to be simple, but I can't figure out how to do it.
There are many list items <li>текст</li>
. I need to select all chunks that have a phrase in their text, like "a year ago". The text also has other html tags.
Such regular expression (php) /<li.+год\ назад.+<\/li>/Us
takes away from the first <li> до последнего </li>
How to find separate li?

Answer 1

you need to reduce the pluses of greed by putting questions after them.
.+x -- up to the last character 'x'
.+? -- everything up to the first character 'x'

Answer 2

doesn't work at all. In this example, if you add another one on top, <li>erfgertwertwer</li>then it will be taken. In addition, \w\s will not skip other html tags.
