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 <table id="ayy"> 43 <tr> 44 <td>ookk</td> 45 <td>aabb</td> 46 </tr> 47 <tr> 48 <td>ccdd</td> 49 <td>eeff</td> 50 </tr> 51 <tr> 52 <td>1122</td> 53 <td>3344</td> 54 </tr> 55 </table> 56 </body> 57 </html> 58 ` 59 60 var table [][]string = GetHtmlTableData(strings.NewReader(html), "#mydata") 61 62 for trkey,tr := range table { 63 for tdkey, _ := range tr{ 64 fmt.Printf("%10s\t|", table[trkey][tdkey]) 65 if len(tr) == (tdkey+1) { 66 fmt.Println("\n","------------------------------------------------") 67 } 68 } 69 } 70 table = GetHtmlTableData(strings.NewReader(html), "#ayy") 71 fmt.Println(table) 72 } 73 74 func GetHtmlTableData(html io.Reader, tableId string) (table [][]string) { 75 var tableCache [][]string 76 77 dom,err:=goquery.NewDocumentFromReader(html) 78 if err != nil{ 79 log.Fatalln(err) 80 } 81 82 trNum := dom.Find("table"+tableId).Find("tr").Length() 83 tdNum := dom.Find("table"+tableId).Find("tr").Find("td").Length() 84 85 tableCache = make([][]string, trNum, trNum) 86 for i:=0; i<trNum; i++{ 87 tableCache[i] = make([]string, tdNum/trNum, tdNum/trNum) 88 for j:=0; j<(tdNum/trNum); j++ { 89 tableCache[i][j] = dom.Find(tableId).Find("tr").Find("td").Eq(i*(tdNum/trNum)+j).Text() 90 } 91 } 92 93 return tableCache 94 }
输出结果如下：
