问题 How would one convert -lrb-300-rrb-┬á922-6590 to -lrb-300-rrb- 922-6590 in java?

Will appreciate any pointers to the solution. Thank you 回答1: Try the next: str = str.replaceAll("[^\\p{ASCII}]", " "); By the way, \p{ASCII} is all ASCII: [\x00-\x7F] . In ahother hand, you need to use a constant of Pattern for avoid recompiled the

问题 Sorry for asking such a simple question, I'm still an inexperienced programmer. I stumbled across a phone-number-matching regex in some old perl code at work, I'd love it if somebody could explain exactly what it means (my regex skills are severely lacking). if ($value !~ /^\+[[:space:]]*[0-9][0-9.[:space:]-]*(\([0-9.[:space:]-]*[0-9][0-9.[:space:]-]*\))?([0-9.[:space:]-]*[0-9][0-9.[:space:]-]*)?([[:space:]]+ext.[0-9.[:space:]-]*[0-9][0-9.[:space:]-]*)?$/i) { ... } Thank you in advance :) 回答1

问题 I have a string consisting of alternating strings of lower-cased letters and numbers (integers or floats), which is of arbitrary length, and I wish to split it into parts, each of maximal possible size, such that a part will consist of either a string or a (string representing a) number. I don't need to regard special forms of numbers, such as exponents, hexadecimal, etc.; just simple floating point or an integer. A few examples: >>> split("") () >>> split("p") ('p',) >>> split("2") ('2',) >>

问题 I'm playing around with the WP editor and I'd like to create a RegEX pattern that matches everything outside the square brackets like this: [foo]Some selected text here[/foo]More selected text here And replace with [foo][text_box text="Some selected text here"][/textbox][/foo] [text_box text="More selected text here"][/textbox] I managed to match the square brackets content using (\[(.*?)\]) How can I match everything else?
