我从 ajax 请求中得到如下输出：

<div style='font-size:12px; font-weight:bold; line-height:17px;'>These results were cached from March 10, 2021, 1:11 pm PST to conserve server resources. <br/>If you are diagnosing a certificate installation problem,

当我尝试td使用以下代码段使用 goquery 进行解析时：

    doc, err := goquery.NewDocumentFromReader(strings.NewReader(pageContent))
    if err != nil {
        panic(err)
    }
    doc.Find("td").Each(func(i int, s *goquery.Selection) {
        fmt.Printf("%s\n", s.Text())
    })

输出：

www.Google.com resolves to 172.217.11.36
 
Server Type:  gws

 
The certificate should be trusted by all major web browsers (all the correct intermediate certificates are installed).
 
The certificate will expire in 62 days. 
                                                        Remind me
The certificate will expire in 62 days. 
Remind me
 
The hostname (www.Google.com) is correctly listed in the certificate.

当我尝试使用b标签而不是td我得到如下输出：

我试图实现的输出是只得到Organization: Google LLC. 我最近开始使用 StackOverflow 和 golang 新手，所以我不熟悉环境，如果我犯了错误，请告诉我。

通过添加一些替换，我能够实现正确的输出。

    res1 := strings.ReplaceAll(pageContent, "</b>", "")
    res2 := strings.ReplaceAll(res1, "<br/>", "</b>")
    doc, err := goquery.NewDocumentFromReader(strings.NewReader(res2))
    if err != nil {
        panic(err)
    }
    doc.Find("b").Each(func(i int, s *goquery.Selection) {
        fmt.Println(s.Nodes[0].FirstChild.Data)
    })

输出：

Common name: www.google.com
SANs: www.google.com

但现在只想要Organization: Google LLC线。
