Regular expressions for all occasions

[LightWood]

We collect the people's list of regulars (regex) for all occasions, I'll start first. Who has their own - throw, add to the first post indicating the author. Regulars can sometimes work incorrectly, if that write off in this thread - we will find a solution.

[TABLE="class: brtb_item_table, border-width: 4px"][TBODY][TR][TH]List of regular expressions and typical usage contexts[/TH][/TR]
[TR][TD]Search for a number greater than 0

(?<=(\D|^))[1-9]\d*

Use case:

In this example, the visible elements are searched for only, the invisible elements (having a width of 0px) are ignored, but sometimes there are misfires - when a site overlays elements (it is found in Google for example).

[TR][TD] Parsing the text for sentences, seems author is ZennoScript, I have slightly modified

work example, initial data:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Fusce dapibus tellus nec nulla gravida, sed congue nunc hendrerit. Integer interdum elementum lorem id rutrum. Ut sit amet interdum mauris. Phasellus mollis ex eleifend lacus molestie dictum. Fusce blandit, ligula non condimentum maximus, massa nisi ullamcorper odio, et vehicula nisl nunc nec orci. Sed neque diam, gravida eu blandit ullamcorper, porttitor non lorem. Etiam sagittis diam a dolor feugiat placerat. Suspendisse enim turpis, imperdiet in tellus sit amet, consectetur porta magna. Suspendisse odio nulla, imperdiet eget augue in, pulvinar hendrerit nunc. Aenean ut cursus tellus, nec vehicula ante. Vestibulum ornare erat non ante tempus, eu aliquet felis dapibus. Vestibulum ante ipsum primis in faucibus orci luctus et ultrices posuere cubilia Curae; Mauris eget arcu imperdiet, laoreet erat non, imperdiet leo.
