replace

This rule checks the input value for a specific pattern. If the pattern is found, it is replaced by a new pattern. This rule only replaces the first instance it finds of the pattern. The syntax for replace is:

<replace regex="regex_pattern" replacement="regex_pattern"/>

The parameters for replace are:

• regex – A regular expression that, if found in the input string, is converted to the replacement expression.

• replacement – The regular expression that replaces the expression specified by the regex parameter.

Example 6 Sample replace Rule

The following sample tries to match the input value against “ST.”. If a match is found, the standardization engine replaces the value with “SAINT”.

<replace regex="ST\." replacement="SAINT"/>
