## How this?
This is a just CLI for an awesome library, [tanakh/easy-scraper](https://github.com/tanakh/easy-scraper).
## Installation
1. Install cargo
- Recommended Way: Install [rustup](https://rustup.rs/)
1. Then,
- `cargo install web-grep`
## Usage
```bash
$ web-grep
```
The `query` is a HTML (XML) Pattern.
Patterns are valid HTML structures which has exact one placeholder `{}` for innerHTMLs or attributes.
For example,
```html
{}
```
```html
{}
```
web-grep outputs all text matching for {}.
NOTE: The original library easy-scraper uses tagged placeholders (e.g. {{xxx}}), but web-grep uses only {}.
