Interpreting HTML stream

In this recipe, we will see how an HTML code may be read and interpreted using regular expressions. We will create a program that will read an HTML stream in a string and will display the tag names along with the content of the tags. The FIND and replace statements are used together with a do loop. (This recipe will focus on reading tags beginning with <tag> and ending with <\tag>).

How to do it...

For creating a program for interpreting HTML code, follow the steps shown in the following steps:

1. Declare three strings by the name htmlstream, tagcontents, and tagname.

2. We then assign a suitable HTML code to the htmlstream variable.

3. Within a do loop, a FIND REGEX statement is added that finds tag names and their contents. The regex used in this case for matching an HTML tag is '<(\u\w*)[^>]*>(.*)</\1>'.

4. Once a tag is processed, a replace all occurrences statement is used for replacing the tag with '$$$'.

5. The tag name and tag contents are printed.

6. Once...
