# XPATH Scraper

Makes it easier to scrape websites with XPATH. Currently using [my xpath parser](https://github.com/Its-its/rust-xpath) which is incomplete, undocumented and used originally for teaching myself about parsing.

A Very simple example of this which is below and also in the [example](/example) folder:
```rust
use std::io::Cursor;

use scraper_macros::Scraper;
use scraper_main::{
	xpather,
	ConvertFromValue,
	ScraperMain
};

#[derive(Debug, Scraper)]
pub struct RedditList(
	// Uses XPATH to find the item containers
	#[scrape(xpath = r#"//div[contains(@class, "Post") and not(contains(@class, "promotedlink"))]"#)]
	Vec<RedditListItem>
);


#[derive(Debug, Scraper)]
pub struct RedditListItem {
	// URL of the post
	#[scrape(xpath = r#".//a[@data-click-id="body"]/@href"#)]
	pub url: Option<String>,

	// Title of the post
	#[scrape(xpath = r#".//a[@data-click-id="body"]/div/h3/text()"#)]
	pub title: Option<String>,

	// When it was posted
	#[scrape(xpath = r#".//a[@data-click-id="timestamp"]/text()"#)]
	pub timestamp: Option<String>,

	// Amount of comments.
	#[scrape(xpath = r#".//a[@data-click-id="comments"]/span/text()"#)]
	pub comment_count: Option<String>,

	// Vote count.
	#[scrape(xpath = r#"./div[1]/div/div/text()"#)]
	pub votes: Option<String>,
}


#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
	// Request subreddit
	let resp = reqwest::get("https://www.reddit.com/r/nocontextpics/").await?;
	let data = resp.text().await?;

	// Parse request into a Document.
	let document = xpather::parse_doc(&mut Cursor::new(data));

	// Scrape RedditList struct.
	let list = RedditList::scrape(&document, None)?;

	// Output the scraped.
	println!("{:#?}", list);

	Ok(())
}
```
