如何使用Excel VBA获取href属性

问题描述

我想检索html页面<h3>标记的href属性，我能够获取innerText，但是我不知道如何访问href属性，其中有几个<h3>标记文档，但是暂时我只需要第一个.稍后我会处理其余的...

I want to retrieve the href attribute of the <h3> tags of an html page, I am able to get the innerText, but I don't know how to access the href attribute, there are several <h3> tags in the document, but for the time being I just need the first one. I will deal with the rest later...

这是我到目前为止得到的代码

This is the code I got so far

Sub Scrap()

Dim IE As New InternetExplorer
Dim sDD As String
Dim Doc As HTMLDocument

IE.Visible = True
IE.navigate "https://www.oneoiljobsearch.com/senior-reservoir-engineer-jobs/?page=1"
Do
DoEvents
Loop Until IE.readyState = READYSTATE_COMPLETE
Set Doc = IE.document
sDD = Trim(Doc.getElementsByTagName("h3")(0).innerText)
'sDD contains the string "Senior Reservoir Engineer"
End Sub

下面是HTML文档的一部分，用于从以下位置提取数据:

Below is a portion of the HTML document to extract data from:

  <div class="front_job_details">

    <h3>
        <a href="/jobs/senior-reservoir-engineer-oslo-norway-7?cmp=js&from=job-search-form-2" target="_blank">

        Senior Reservoir Engineer

        </a>
    </h3>

我需要检索的文本是:"/jobs/senior-reservoir-engineer-oslo-norway-7?cmp = js& from = job-search-form-2"

The text I need to retrieve is: "/jobs/senior-reservoir-engineer-oslo-norway-7?cmp=js&from=job-search-form-2"

在此先感谢您的帮助.

Thanks in advance for your help.

推荐答案

尝试

dim hr as string

hr = Doc.getElementsByTagName("h3")(0).getElementsByTagName("a")(0).href

debug.print hr

getElementsByTagName集合是从零开始的，而.Length(H3的数量，在其他方法中称为Count)是从一开始的.

The getElementsByTagName collection is zero-based but the .Length (the # of H3's, called Count in other methods) is one-based.

dim i as long

for i=0 to Doc.getElementsByTagName("h3").length - 1
    debug.print Doc.getElementsByTagName("h3")(i).getElementsByTagName("a")(0).href
next i

这将获得第一个< A>每个H3中的标签.您可以复制该方法，以从每个H3中获取多个A.

This gets the first <A> tag from each H3. You could duplicate the method to get multiple A's from each H3.
