ATTRIBUTES in HTML

ATTRIBUTES: ADDITIONAL INFORMATION ABOUT AN ELEMENT Sometimes we have HTML elements that need to have more defined information about them. Enter " Attributes ". Think of an HTML attribute like an adjective or an adverb. Adjectives and adverbs describe the noun/verb. It gives additional information. Attributes work in a very similar way. They give additional information about the element. Attributes are always specified in the start tag. Please take a look at the two photos below: (a) (b) In the first picture (a), you see the HTML code for the web site. If you look at the < h1 > tag (located under the < body > tag), you see that it is the element tag for a header. The contents in between the opening and closing < h1 > tags says "Hello World!".

A root element is the sole parent element to all other elements in the document. What this means is that every other element within the HTML document is going to be either a child or a grandchild of the root element.

For HTML, that root element opening tag will always look like this: <html> . The </html> closing tag will be at the end. Please see the picture below: HTML ELEMENTS START AND END/CLOSING TAGS : Most HTML elements have a start tag and an end tag with the ...

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?

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.

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 an...
