xml - Parsing WordPress RSS Feed with JQuery -


i using jquery read , parse self-hosted wordpress atom feed. here's example of xml generated wordpress:

<?xml version="1.0" encoding="utf-8"?> <feed   xmlns="http://www.w3.org/2005/atom"   xmlns:thr="http://purl.org/syndication/thread/1.0"   xml:lang="en-us"   xml:base="http://example.com/wp/wp-atom.php"    >     <title type="text">feed title</title>     <subtitle type="text">feed subtitle</subtitle>     <updated>2013-04-19t21:33:48z</updated>     <link rel="alternate" type="text/html" href="http://example.com/wp" />     <id>http://example.com/wp/index.php/feed/atom/</id>     <link rel="self" type="application/atom+xml" href="http://example.com/wp/index.php/feed?feed=atom&#038;cat=10" />     <generator uri="http://wordpress.org/" version="3.5.1">wordpress</generator>     <entry>         <author>         <name>author name</name>         </author>         <title type="html">article title</title>         <link rel="alternate" type="text/html" href="http://example.com/wp/index.php/2013/04/19/article-title/" />         <id>http://example.com/wp/?p=1418</id>         <updated>2013-04-19t21:33:48z</updated>         <published>2013-04-19t21:33:16z</published>         <category scheme="http://example.com/wp" term="firstcategory" />         <category scheme="http://example.com/wp" term="secondcategory" />         <category scheme="http://example.com/wp" term="thirdcategory" />         <summary type="html">a summary excerpt of article [...]</summary>         <content type="html" xml:base="http://example.com/wp/index.php/2013/04/19/tons-vs-tonnes/">a summary excerpt of article whole bunch more text taht not in summary.         </content>         <link rel="replies" type="text/html" href="http://example.com/wp/index.php/2013/04/19/article-title/#comments" thr:count="0"/>         <link rel="replies" type="application/atom+xml" href="http://example.com/wp/index.php/2013/04/19/article-title/feed/atom/" thr:count="0"/>         <thr:total>0</thr:total>     </entry> </feed>

here's jquery ajax code consume feed , display it:

$.ajax({     url: "//example.com/wp/index.php/feed?feed=atom&cat=10",     datatype: "xml",     success: function(data) {         console.log(data);         var $xml = $(data),             items = [];          $xml.find("entry").each(function(i) {             if (i === 30) return false;             var $this = $(this);             console.log($this);              items.push('<div><h3>' + $this.find("title").text() + '</h3><p><small>published ' + $this.find("author").text().trim() + ' on ' + publisheddate.todatestring() + ' ' + publisheddate.totimestring() + '</small></h3>' + $this.find("content").text() + '</div><hr />');         });         $("#displaydiv").html(items.join(''));

this working!! want enhance list of category tags entry follows:

firstcategory | secondcategory | thirdcategory

if @ xml, notice there 3 category elements in sample entry.

i've tried several methods , have failed miserably. i've reverted working code have extracted above sample javascript, don't have failed attempts left show you.

in code use publisheddate.totimestring() gives error.

to catgeories use like:

            var categories = "";              $this.find("category").each(function(j) {                 categories += " " + ($(this).attr("term"));             })               items.push("categories:" + categories);

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!
