php - How can I re-parse an XML document at set intervals? -


i have built area on client's website displays song playing, parsed xml file via php. however, client wants song auto-refresh instead of him having manually refresh page.

i played around parsing file using jquery.get() , .ajax(), because of way xml file structured, seems though can artist , name squashed 1 string, or when try specific returns [object object].

i haven't tried tackle having song's length calculated , refresh feed based on length. may not seeing apparently such issue me.

any or general guidance appreciated.

example working php code (obviously, non-ajax):

<?php     $recentlyplayed = simplexml_load_file('http://publicapi.streamtheworld.com/public/nowplaying?mountname=abcdfm&numbertofetch=1&eventtype=track');     $tracktitle = $recentlyplayed->{'nowplaying-info'}[0]->property[1];     $trackartist = $recentlyplayed->{'nowplaying-info'}[0]->property[0];     echo "<h6>" . $trackartist . "<span class=\"song-title\">" . $tracktitle . "</span></h6>"; ?>

i've tried several different things work, seems initial obstacle trying reference data in xml file using attributes, rather node-names. nodes named same, , it's attributes differentiate them. so, such code render correctly, unless artist/song title blank, renders third field sort of cryptically-named "cue_time_start".

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" ></script> <script type="text/javascript">     $(document).ready(function() {         setinterval("songpull()",1000);     });      function songpull() {         $.get(             "http://publicapi.streamtheworld.com/public/nowplaying?mountname=abcdfm&numbertofetch=1&eventtype=track",              "xml",             function(data) {                 $(data).find("nowplaying-info").each(function(){                     var artist = $(this).find("property").eq(0).text();                     var title = $(this).find("property").eq(1).text();                     $('body').html("<h1>" + artist + "<small class=\"song-title\">" + title + "</small></h1>");                     console.log (artist);                     console.log (title);                 });             }         );     } </script> <body>  </body>

any guidance, advice or examples of best practices when trying sort of thing appreciated.

i'm not sure if want, use attribute selectors extract data want out of xml document.

http://jsfiddle.net/p8dc6/

$.get("http://publicapi.streamtheworld.com/public/nowplaying?mountname=kroxfm&numbertofetch=1&eventtype=track",      "xml",     function(data) {         var $nowplaying = $(data).find('nowplaying-info');         console.log($nowplaying.find('[name=track_artist_name]').text());         console.log($nowplaying.find('[name=cue_title]').text());     } );

also, never pass string setinterval or settimeout, can pass function reference directly:

setinterval(songpull ,1000);

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!
