Regularity is regarded as a specific condition mathematically; however, due to natural repetition of elements in FE models, regular/near-regular patterns are very common in these models. In this paper, graph product mathematical formulations for FE models are developed, and the efficiency of the ...

Greedy repetition operator takes as many matching characters as possible, non-greedy takes as few as possible. For example,b+andb*applied to stringabbbbcwill returnbbbb, whereasb+?will returnbandb*?will return an empty string. Switching to non-greedy mode makes+work as+?,*as*?and so on....
repetition operators Explicit parentheses can be used to force different meanings, as in arithmetic expressions. Some examples:ab|cdis equivalent to(ab)|(cd);ab\is equivalent toa(b\). The syntax described so far is most of the traditional Unixegrepregular expression syntax. This subset suffices...

preg_grep() Returns the elements of the input array that matched the pattern. preg_split() Splits up a string into substrings using a regular expression. preg_quote() Quote regular expression characters found within a string.Note: The PHP preg_match() function stops searching after it finds...

This section describes all of the elements of ActionScript regular expression syntax. As you’ll see, regular expressions can have many complexities and nuances. You can find detailed resources on regular expressions on the web and in bookstores. Keep in mind that different programming environments ...
You can group individual elements of an expression together in order to support complex matches. Searching for two people’s names could be achieved with two separate tests, like this −if (($string =~ /Martin Brown/) || ($string =~ /Sharon Brown/)) This could be written as follows ...
