How to find a specific word using Regex?

Question

I`m trying to select DataTable rows using regex. I want to found all rows that have only the word "Venta" and omit "Renta/Venta" and also "Renta".

Examples of possibles strings:

"whatever whatever Venta/Renta whatever"

"whatever whatever Venta whatever "

"whatever whatever Renta whatever "

I only want to select the string that only have "Venta" alone. Now I using "(?!Renta/Venta)Venta" but still selects the rows that have "Renta/Venta".

Answer 1

使用空格字符（ \\s ）：

/(^|\s)Venta(\s|$)/

Answer 2

在这里检查： https : //regex101.com/r/Ja7Vg8/1

.*\bVenta\b[^\/].*

Answer 3

If the string are built that way, then you can use a regex with negative lookahead like this:

.*Venta(?!\/Renta).*

Keep in mind that it won't work if the string is:

whatever Renta whatever Venta whatever

So, if strings like above are present, then you can use a trick like this:

^(.(?!Renta))+$
