XMLLINT for HTML: Cleaning up the HTML Code

Getting That MESS Cleaned Up!

In an earlier post, we learned about xmllint. Today, I want to talk about cleaning up the code for an HTML file.

When we have an xml file, xmllint is used. For an html file, we use the following command in the command line:

xmllint --html <filename goes here>

Here is an actual command on my command line for running xmllint for my StedmanLesson10.html file.

In the photo above, you see that I start off the command with xmllint.

The next thing is a space and then a --html. The two -- are two hyphen-minus characters that are used to specify long options (Basically there are options that can be used within xmllint. The two hyphen-minus characters are saying an option is going to be used. In this case, that option will be html - because we are going to do an xmllint on an html file).

After that you see a space and then the name of the html file I want the xmllint to be done on.

The outcome of this command can be seen below:

NOTICE in the picture above, that the top line is the command I inputed and the lines following are the xmllint parsings of my file. You are able to see that there were no errors found in the xmllint of my html file and that my html code is shown on the command line.

BUT WAIT...

What if you want to just parse (analyze a string of symbols) a certain tag within the html file?

Let's say, for example, you only just wanted to see all of the <span> tags within the html file... how would you do that?

For that answer, you need to see my post on XPATH And XPATH Expressions. 😊

XPATH and XPATH Expressions In XMLLINT

XPATH And XPATH Expressions Earlier, I told you about xmllint and xmllint for html files . Let's say you just want to parse the <span> tags within your html file or just your <span lang="el"> tags? Enter: Xpath. Xpath is yet another option available within the xmllint language. Remember, an Xpath is used to navigate through elements and attributes in xml and html documents. Xpath uses Xpath Expressions to select nodes or node sets within a document. Example 1 . Looking for all of the <span> tags within an html document. xmllint -- html -- xpath " // span" StedmanLesson10.html xmllint = This tells the command line that we are going to be using the xmllint language. space = because we always have space in between commands -- = Remember, these are the two hyphen-minus characters that we need to tell the command line that we are going to use an xmllint option. html = This is the xmllint option we want to

Back To The Basics

Click photo above to see photo clearly It's Been A LOOONG Minute since I have coded!! Even so, I decided to give JavaScript another try. I always seem to do good and then when I get to this one area, I always seem to hit a brick wall. Well....nothing like getting back up and trying again right? I decided to try Rithm School's online JavaScript Fundamentals FREE course . I have never joined their school but their free courses tend to explain things in a way my brain understands it. 💁 To let you know how much I have forgotten in the coding world, I couldn't even remember how to write the basic commands for an HTML document! Yesterday I started the fundamentals free course and I am so glad that I did. Because of time, I only made it through the JavaScript History and Setup chapter, but that chapter was enough to get my memory flowing again! It started to feel familiar and I quickly remembered why I enjoyed coding so much. Yesterday and this morning, I just erased

SCP: Secure Copy Protocol

SCP = Secure Copy Protocol. What is it and why is it important? SCP provides a secure way to transfer files from one computer to another. For the project that I'm working on, I needed to SCP (send a copy) the XML files, as well as the image files, from my computer to my EC2 Instance (my web server). Once done, my teacher was be able to view my work via my website. Here are the steps to do this: 1. Open two command windows (the program for my computer is called Terminal). 2. Let's say the file I want to send is called "SallysFirstDate.xml" and it is located in the "tomy" folder. Here is where that file lives: /Documents/path/tomy/SallysFirstDate.xml I need to first issue the command to "change directory"(cd) through each folder until I reach the folder that my file is located in. It would look like this: cd /Documents THEN I need to "cd" again into the "path" folder: cd path THEN I need to "c
