I am getting the following String response from a server: {"fid":"1272","uri":"http://someurl/services/file/1272"} I need to convert it into a JSONArray . Any help? By the way, I tried this and it does not work: String response=getResponseFromServer(); JSONArray array = new JSONArray(response); I get the error: org.json.JSONException: Value {"fid":"1272","uri":"http://someurl/services/file/1272"} of type org.json.JSONObject cannot be converted to JSONArray If you're talking about using the JSON in java library, then since your input string is a JSON object, not a JSON array, you should first

I'm using the following code to convert my XML file to a CSV format. Unfortunately, it seems to not be recognizing each entry in the XML and so the XML file ends up being blank. <?php $filexml='test.xml'; if (file_exists($filexml)) { echo 'File Exists'; $xml = simplexml_load_file($filexml); $f = fopen('test.csv', 'w'); foreach ($xml->Item as $item) { fputcsv($f, get_object_vars($item),',','"'); } fclose($f); } ?> An example of my XML file is below... <Item MaintenanceType="C"> <HazardousMaterialCode>N</HazardousMaterialCode> <ItemLevelGTIN GTINQualifier="UP">090127000380</ItemLevelGTIN>

How to convert datetime to integer in python

how can i convert YYYY-MM-DD hh:mm:ss format to integer in python? for example 2014-02-12 20:51:14 -> to integer. i know how to convert only hh:mm:ss but not yyyy-mm-dd hh:mm:ss def time_to_num(time_str): hh, mm , ss = map(int, time_str.split(':')) return ss + 60*(mm + 60*hh) ely It depends on what the integer is supposed to encode. You could convert the date to a number of milliseconds from some previous time. People often do this affixed to 12:00 am January 1 1970, or 1900, etc., and measure time as an integer number of milliseconds from that point. The datetime module (or others like it)

Converter to show description of an enum, and convert back to enum value on selecting an item from combo box in wpf

问题 I am using an enum to enlist values in my combobox. I want to write a converter that would show the "description" of the selected enum value. And, when selected, it would return the enum value. Most of the converters online have not implemented the ConvertBack() method (which is why I am posting here). Thanks in advance. 回答1: Here is ConvertBack method: public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { return value; } Full

Avoid extra DB reads in the getAsObject method of converter class by caching data client side?

ぃ、小莉子 提交于 2019-11-29 07:40:27
I'm showing a list of suggested items in an autocomplete input element. For that I need to implement a converter to convert the entity<entityName, entityId> to entityName & vice versa. However while implementing that I realized that I had to read the DB more than 1 time to find the corresponding entityId for the chosen entityName(while getAsObject() ), I am wondering why isn't this stored somewhere client side so that the entityId could be passed when the entityname is selected. Is there any way I could avoid this extra read? This is indeed "by design" and perhaps a little oversight in the JSF

iOS to Mac GraphicContext Explanation/Conversion

泪湿孤枕 提交于 2019-11-29 07:36:43
问题 I have been programming for two years on iOS and never on mac. I am working on a little utility for handling some simple image needs that I have in my iOS development. Anyway, I have working code in iOS that runs perfectly but I have absolutely no idea what equivalents are for mac. I've tried a bunch of different things but I really don't understand how to start a graphics context on the Mac outside of a "drawRect:" method. On the iPhone I would just use UIGraphicsBeghinImageContext(). I know

PHP not have a function for XML-safe entity decode? Not have some xml_entity_decode?

倖福魔咒の 提交于 2019-11-29 07:23:40
THE PROBLEM : I need a XML file "full encoded" by UTF8; that is, with no entity representing symbols, all symbols enconded by UTF8, except the only 3 ones that are XML-reserved, "&" (amp), "<" (lt) and ">" (gt). And, I need a build-in function that do it fast : to transform entities into real UTF8 characters (without corrupting my XML). PS: it is a "real world problem" (!); at PMC/journals , for example, have 2.8 MILLION of scientific articles enconded with a special XML DTD (knowed also as JATS format )... To process as "usual XML-UTF8-text" we need to change from numeric entity to UTF8 char.
