.net - Regex - Match Last Occurance -


i have text file full of names, want match them via regex.

each name ends following text: fsa fwb fcc, eg:

">dave smith\u0012\/a>\u0012\/div>\u0012div class=\"fsa fwb fcc

i want use following expression match names:

""">.+?""fsa fwb fcc"

aka match text "> fsa fwb fcc, can parse excess matched myself.

however "> occurs throughout file, starts matching earlier. have wondered how match last occurance of something, in case, ">, end specified.

thanks all, stan.

description

it looks you're ending string literally fsa fwb fcc, , beginning of substring you're interested in starts directly after last "> before end string.

this expression will:

  • find substring between last "> , next fsa fwb fcc

">((?:(?!">).)*)fsa\sfwb\sfcc

sample text

">sometext">a dave smith\u0012\/a>\u0012\/div>\u0012div class=\"fsa fwb fcc ">sometext">b dave smith\u0012\/a>\u0012\/div>\u0012div class=\"fsa fwb fcc ">sometext">c dave smith\u0012\/a>\u0012\/div>\u0012div class=\"fsa fwb fcc

matches found:

[0][0] = ">a dave smith\u0012\/a>\u0012\/div>\u0012div class=\"fsa fwb fcc [0][1] = dave smith\u0012\/a>\u0012\/div>\u0012div class=\"  [1][0] = ">b dave smith\u0012\/a>\u0012\/div>\u0012div class=\"fsa fwb fcc [1][1] = b dave smith\u0012\/a>\u0012\/div>\u0012div class=\"  [2][0] = ">c dave smith\u0012\/a>\u0012\/div>\u0012div class=\"fsa fwb fcc [2][1] = c dave smith\u0012\/a>\u0012\/div>\u0012div class=\"

or

if want go further , capture last "> through \u0012 before fsa fwb fcc ... i.e. actual name , not markup text, have @ expression

">((?:(?!">).)*?)\\u0012(?:(?!">).)*fsa\sfwb\sfcc

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
