Taking on the DOM !!!


IT'S TIME TO LEARN THE DOM 😆

Today I am tackling the DOM so the FIRST thing I did was to put on my StarWars shirt!  I am definitely going to need the Force to be with me as I learn how to access and manipulate XML and HTML in the DOM.

First thing first----> What is the DOM?

DOM stands for Document Object Model.  It is the browser's representation of the page in memory.  The browser creates the DOM to allow us to modify and change XML, HTML, and CSS.  If you change the DOM, you change the page (using JavaScript).

WHY would we want to work in the DOM?

It is a useful tool for developers because it allows  a website to be manipulated in a live environment.  Once changes made are acceptable and approved, that code that was implemented in the DOM can then be copied over to the actual XML/HTML index file.  It can then be saved and implemented so that the website will have the current changes for all end users.

How do we access the DOM and how does it work?

Whenever a webpage is loaded, the browser automatically creates the DOM for that page.  To access the DOM, you can right click on the page you are viewing.  Select "Inspect", then select "Console".  Type "document."  then press return.  Now you will see the DOM.


In the picture above, I went into the DOM on Yahoo's webpage.  Notice that I typed "document." above right.

I am using a Mac, so to access the DOM above, I used the short cut 'Option Command J' instead of right clicking, Inspect, etc.


Look for my next post where I talk about DOM selectors.

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 ...

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 t...

GIT Commands: Pull, Add, Commit, Push.....and sometimes Revert

Pull, Add, Commit, Push ...... then Repeat We talked about GIT, GIT Hub , and the three different areas GIT works in.  Now it is time to talk about some of the most used GIT commands.   I am currently working with a team on a project called Stedman.  We are all using the GIT Hub server to track our work as we make changes to the files within the Stedman project.   Many changes can be made by other members of the team, from the time I sign off to the time I sign back on.  How do I get the changes they made to a file I need to work on, onto my computer? ENTER GIT COMMANDS : 1.  The first thing I do is goto my command window on my computer and navigate to the directory where the file I want to work in is located (this will be a directory that is being tracked by GIT).   *If you need a quick refresher:  cd file_name   will take you through each of your directories until you reach your desired loca...
