如何使用jquery提取子文本数据？(how extract child's text data using jquery?)

我想从下面给出的html中提取数据'AT401726'

<td class="publicationInfoColumn"> <h4>Publication info:</h4> AT401726<br>2008-08-15 </td>

＆我使用JQuery解决了它，下面给出了工作代码

('body').find('.publicationInfoColumn').clone().children().remove().end().text()

是否还有其他更好的技术从上面给出的HTML提取数据？ 在我的抓取的html页面中有很多像上面这样的html

i want to extract data 'AT401726' from the html given below

<td class="publicationInfoColumn"> <h4>Publication info:</h4> AT401726<br>2008-08-15 </td>

& i solved it by using JQuery, the working code is given below

('body').find('.publicationInfoColumn').clone().children().remove().end().text()

is there any other better technique to extract data from above given html ? there are many html like above in my crawled html page

最满意答案

您正在寻找h4元素的下一个兄弟元素的内容，请尝试

var text = $.trim($('.publicationInfoColumn h4').prop('nextSibling').nodeValue); console.log(text)

演示： 小提琴

The text you are looking for the the contents of the next sibling element of the h4 element, so try

var text = $.trim($('.publicationInfoColumn h4').prop('nextSibling').nodeValue); console.log(text)
