c# - Getting Matched HTML Value with Regex -

-

ok start know should not using regex parse html it's not reliable, not 100% safe, etc. however, learning excercise regex as else.

so example uses bbc website http://www.bbc.co.uk/sport/football/premier-league/table.

the project parsing tbody of first table. trying search elements matching search value returned. example, given search "manc" want tr tag manchester city , manchester united (matched url).

what have far <tr\b[^>]*>(.*?)manc(.*?)</tr> matches first tr closing tr after man city , returns expected result man utd. point out i've gone wrong regex.

edit: source (trimmed)

the problem is, regular expression broad. you're asking for:

<tr\b[^>]*>(.*?)manc(.*?)</tr>

lets simplify little bit. 

<tr>.*?manc.*?</tr>

so you're saying, ok. need match tr followed anything , manc , , closing tr. so. of course happens regex starts @ first tr , goes ok. i've got tr let me keep matching until find manc. in meantime, passed bunch of other tr. regex doesn't care.

try this:

<tr>(?:(?!</tr>).)*manc.+?</tr>

or, guess in example:

<tr\b[^>]*>(?:(?!</tr>).)*manc.+?</tr>

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
