Searching with Regular Expressions
(option unique to TreePad™ Business Edition)
For advanced users.
A regular expression is phrase or formula, representing a pattern. A regular expression allows you to search in an extremely flexible way for the occurence of certain strings within articles and nodes.
An everyday example of a regular expression is the usage of the wildcard character * when searching for files.
For instance, when using the phrase *.txt during a file search, you have used a simple regular expression to locate text files.
In other words, in this example, the regular expression *.txt represents all files having a name ending in .txt.
Please note that regular expressions are case-sensitive by default.
