Below are most common 15 different ways to create Regular Expressions:<br><a><\/a><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Using the Backslash Character:&nbsp;<\/strong>A backslash (\\) can serve two purposes. It can be used in conjunction with a special character to indicate that the next character be treated as a literal character. For example, \\.would be treated as period (.) instead of a wildcard. Alternatively, if the backslash (\\) is used in conjunction with some characters that would otherwise be treated as literal characters, such as the letters n, t, w, or d, the combination indicates a special character. For example, \\n stands for the newline character.<\/li>\n\n\n\n<li><strong>Matching Any Single Character:&nbsp;<\/strong>A period (.) instructs QTP to search for any single character (except for \\n).<\/li>\n\n\n\n<li><strong>Matching Any Single Character in a List:&nbsp;<\/strong>Square brackets instruct QTP to search for any single character within a list of characters.<\/li>\n\n\n\n<li><strong>Matching Any Single Character Not in a List:&nbsp;<\/strong>When a caret (^) is the first character inside square brackets, it instructs QTP to match any character in the list except for the ones specified in the string.<\/li>\n\n\n\n<li><strong>Matching Any Single Character within a Range:&nbsp;<\/strong>To match a single character within a range, you can use square brackets ([ ]) with the hyphen (-) character.<\/li>\n\n\n\n<li><strong>Matching Zero or More Specific Characters:&nbsp;<\/strong>An asterisk (*) instructs QTP to match zero or more occurrences of the preceding character.<\/li>\n\n\n\n<li><strong>Matching One or More Specific Characters:&nbsp;<\/strong>A plus sign (+) instructs QTP to match one or more occurrences of the preceding character.<\/li>\n\n\n\n<li><strong>Matching Zero or One Specific Character:&nbsp;<\/strong>A question mark (?) instructs QTP to match zero or one occurrences of the preceding character.<\/li>\n\n\n\n<li><strong>Grouping Regular Expressions:&nbsp;<\/strong>Parentheses (()) instruct QTP to treat the contained sequence as a unit, just as in mathematics and programming languages. Using groups is especially useful for delimiting the argument(s) to an alternation operator ( | ) or a repetition operator ( * , + , ? , { } ).<\/li>\n\n\n\n<li><strong>Matching One of Several Regular Expressions:&nbsp;<\/strong>A vertical line (|) instructs QTP to match one of a choice of expressions.<\/li>\n\n\n\n<li><strong>Matching the Beginning of a Line:&nbsp;<\/strong>A caret (^) instructs QTP to match the expression only at the start of a line, or after a newline character.<\/li>\n\n\n\n<li><strong>Matching the End of a Line:&nbsp;<\/strong>A dollar sign ($) instructs QTP to match the expression only at the end of a line, or before a newline character.<\/li>\n\n\n\n<li><strong>Matching Any AlphaNumeric Character Including the Underscore:&nbsp;<\/strong>\\w instructs QTP to match any alphanumeric character and the underscore (A-Z, a-z, 0-9, _).<\/li>\n\n\n\n<li><strong>Matching Any Non-AlphaNumeric Character:&nbsp;<\/strong>\\W instructs QTP to match any character other than alphanumeric characters and underscores.<\/li>\n\n\n\n<li><strong>Combining Regular Expression Operators:<\/strong>&nbsp;You can combine regular expression operators in a single expression to achieve the exact search criteria you need.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>In QTP, there are multiple ways to create Regular Expressions.
