This recommended combination is Xml.dom.minidom and XPath. Where Xml.dom.minidom is the standard library for Python, no installation is required. XPath is an open source project Py-dom-xpath by Google.

Install Py-dom-xpath:

    1. Download the compressed package from https://py-dom-xpath.googlecode.com/files/py-dom-xpath-0.1.tar.gz, unzip it.
    2. CD to py-dom-xpath-0.1 directory
    3. Execute command: C:\python27\python setup.py install
    4. After the command executes, this directory has two more folders, build and dist, and copies the XPath directory under the/build/lib/folder to the C:\Python27\Lib directory, which is the installation complete.

The test HTML file, simple.html, reads as follows:

  

1 <!DOCTYPE HTML>2 <HTML>3 <Head>4 <title>A simple HTML file</title>5 <Metahttp-equiv= "Content-type"content= "text/html; charset=utf-8"/>6 </Head>7 <Body>8 <Div>9     <Div>A</Div>Ten     <Div>B</Div> One     <Div>C</Div> A </Div> - </Body> - </HTML>

Python file:

  

 1  import   XPath  2  import   Xml.dom.minidom  3  4  xml = Xml.dom.minidom.parse ( '  

A notable problem is that the first line of simple.html, the document header <! The ' DOCTYPE ' in DOCTYPE html> must be capitalized, otherwise xml.dom.minidom parsing will fail. In the next article, we'll cover another library that parses HTML, and there's no such problem.
