Golang读取HTML中Table数据到二维数组
作者：互联网
利用goquery读取html中指定ID的数据保存至二维数组中。
代码如下：
1 package main
2
3 import (
4 "fmt"
5 "log"
6 "strings"
7 "io"
8
9 "github.com/PuerkitoBio/goquery"
10 )
11
12 func main() {
13 html := `<html>
14 <body>
15 <table id="mydata">
16 <tr id="one">
17 <td>one</td>
18 <td>two</td>
19 <td>three</td>
20 </tr>
21 <tr id="two">
22 <td>3</td>
23 <td>4</td>
24 <td>5</td>
25 </tr>
26 <tr id="three">
27 <td>八</td>
28 <td>九</td>
29 <td>十</td>
30 </tr>
31 <tr id="four">
32 <td>百</td>
33 <td>千</td>
34 <td>万</td>
35 </tr>
36 <tr id="five">
37 <td>100</td>
38 <td>200</td>
39 <td>300</td>
40 </tr>
41 </table>
42 </body>
43 </html>
44 `
45
46 var table [][]string = GetHtmlTableData(strings.NewReader(html), "#mydata")
47
48 fmt.Println(table)
49
50 for trkey,tr := range table {
51 for tdkey, _ := range tr{
52 fmt.Println(table[trkey][tdkey])
53 }
54 }
55 }
56
57 func GetHtmlTableData(html io.Reader, tableId string) (table [][]string) {
58 var tableCache [][]string
59
60 dom,err:=goquery.NewDocumentFromReader(html)
61 if err != nil{
62 log.Fatalln(err)
63 }
64
65 trNum := dom.Find("table"+tableId).Find("tr").Length()
66 tdNum := dom.Find("table"+tableId).Find("tr").Find("td").Length()
67
68 tableCache = make([][]string, trNum, trNum)
69 for i:=0; i<trNum; i++{
70 tableCache[i] = make([]string, tdNum/trNum, tdNum/trNum)
71 for j:=0; j<(tdNum/trNum); j++ {
72 tableCache[i][j] = dom.Find(tableId).Find("tr").Find("td").Eq(i*(tdNum/trNum)+j).Text()
73 }
74 }
75
76 return tableCache
77 }
输出结果如下：
