# Tag Replacement Techniques

## Simple tag replacement.

A special tag is inserted in the html page, where we desire data to be inputted. The tag could be of the form “`$tag_name$`” or any other selected format that will uniquely identify it in the html page.

Use the “**Template Replacer**” rule to replace unique tags in the html page with the values of given parameters.

## Tag replacement with parent tag repetition.

It is similar to the previous technique, with the added benefit of finding the parent html tag of the unique tag, in order to repeat it.

This is useful, for example, when we want to add new table rows without changing the already existing attributes and style of the “`<tr`” parent tag.

It can also be used for html options or html lists.
