如何在VB.NET（Visual Basic 2010）中使用跨度ID从HTML获取文本？

Question

How do I get a string from an HTML document using span ID in VB.NET (Visual Basic 2010)?

I am working on a project, and I wanted to extract text from a webpage span to my application's textbox1.text . I only used this so far:

TextBox1.Text = WebBrowser1.Document.All.GetElementsByName("***I put the span id here, but it didn't work.***")(0).InnerText

You are using ...ByName and not ...ByID which mean you need to use the name attribute of the span element:

<span name="myName">...</span>

To use ID instead of name try replacing your code to (untested):

TextBox1.Text = _
 WebBrowser1.Document.GetElementById("spanID").GetAttribute("innerText")

...

<span id="spanID">...</span>
