Figure 6-14

This was a simple example, but we’re sure you can intuit how useful this system can be when building a

more complex content management system. This little script currently knows how to handle these custom

markup tags, whose significance is obvious:

{bold}

,

{italic}

,

{underline}

,

{heading}

,

{subhead-

ing}

,

{link}

,

{elink}

(this is a link that opens a new window),

{unordered-list}

,

{ordered-list}

,

{list-element}

,

{picture}

, and

{comment}

.

The markup file,

markup.txt

, doesn’t contain any HTML elements, but custom markup elements. How

-

ever, with the help of a simple (but quite long) custom markup library, you’re replacing on-the-fly all the

custom markup elements with standard HTML tags.

The

custom_markup_translate()

function consists mainly of a number of regular expression replace-

ments, which transform the custom markup code to HTML. We’re leaving understanding this function

for you as an exercise.
