# A Simple HTML-Parser

**安装：**  `go get github.com/pysrc/bs` 

## 快速开始

```go

package main

import (

	"fmt"

	"github.com/pysrc/bs"

)

var html_doc = `

The Dormouse's story

The Dormouse's story


Once upon a time there were three little sisters; and their names were

Elsie,

Lacie and

Tillie;

and they lived at the bottom of a well.


...

`


func main() {

	soup := bs.Init(html_doc)

	// 找出所有 a 标签的链接

	for i, j := range soup.SelByTag("a") {

		fmt.Println(i, (*j.Attrs)["href"])

	}

	/*Output:

	  0 http://example.com/elsie

	  1 http://example.com/lacie

	  2 http://example.com/tillie

	*/

	// 获取属性 class="story" 的 p 标签

	for i, j := range soup.Sel("p", &map[string]string{"class": "story"}) {

		fmt.Println(i, "Tag", j.Tag)

		// 找出子标签为 a 的标签

		for k, v := range j.SelByTag("a") {

			fmt.Println(k, "son", v.Value)

		}

	}

	/*Output:

	  0 Tag p

	  0 son Elsie

	  1 son Lacie

	  2 son Tillie

	  1 Tag p

	*/

	for _, j := range soup.SelById("lin.*") { // 使用正则匹配

		fmt.Println("regex", j.Tag, j.Value)

	}

	/*Output:

	  regex a Elsie

	  regex a Lacie

	  regex a Tillie

	*/

	// 从url直接解析

	soup = bs.Init("https://github.com/")

	for _, j := range soup.Sel("title", nil) {

		fmt.Println("title:", j.Value)

	}

	/*Output:

	  title: The world’s leading software development platform · GitHub

	  title: 1clr-code-hosting

	*/

}

```

## 可用接口

### 1.方法

```go

type SelFunc interface {

	Sel(tag string, attrs *map[string]string) (nodes []*Node)

	SelById(id string) []*Node

	SelByTag(tag string) []*Node

	SelByClass(class string) []*Node

	SelByName(name string) []*Node

}

```

### 2.可操作属性

```go

type Node struct { // 基本节点结构

	Tag   string             // 标签名

	Attrs *map[string]string //属性

	Value string             // 此节点的值

	Sons  []*Node            // 子节点

}

```
