<thatstar />

The thatstar element is used to echo wildcard contents found inside of <that> tags.

Attributes

index Specifies the index of the wildcard to echo. If no index is specified, defaults to 0.

Usage

<category>
<pattern>I LIKE IT TOO</pattern>
<that>I LIKE *</that>
<template>What do you like best about <thatstar /></template>
</category>

Input:
Output: I like coffee.
Input: I like it too.
Output: What do you like best about coffee?

This type of category is useful for dealing with pronoun resolution (anaphora). If the user inputs the word “it”, you can implement a that element and a thatstar element to keep a reference to the original noun in question.
