i'm currently web scraping an ecommerce website which i am choosing the prices of the products. The price follows this format:

> 
> $4.500
> 
> 
> 

And i currently have this in the regExr of the web scraping software: 

```
[0-9]+\.[0-9]+

```

I'm currently just looking how can i remove the dollar sign and the dot? To leave it like this

> 
> 4500
> 
> 
> 

What i understand from regex is that i can match the $ and . character. So i tried it on [regex101.com](https://regex101.com/) this:

> 
> \$[0-9]+.[0-9]+
> 
> 
> 

What is the regex so i can match certain characters and delete them?
