  • Force jQuery to accept XHTML string as XML?

    - by MidnightLightning
    So, as part of a baseline OpenID implementation in Javascript, I'm fetching a remote page source through AJAX, and looking for the <link rel="openid.server" href="http://www.example.com" /> tag in the head. I'm using the jQuery javascript library for the AJAX request, but am unable to parse out the link tags. Several other online sources talk about using the usual jQuery selectors to grab tags from XML/XHTML sources, but it seems jQuery can only get content from the body of an HTML document, not the head (which is where the link tags are; $(response).find('link') returns null). So, I'd either need to get jQuery to force this document into XML mode or otherwise get at the head tags. Is there a way to force jQuery to parse the response of an AJAX query as XML, when it's in reality XHTML? Or do I need to fall back to regular expressions to get the link tags out?

  • Parse string with bash and extract number

    - by cleg

Please help me to find a way how to do it, thanks in advance.

  • Setting the background colour/highlight colour for a given string range using Core Text

    - by Jasarien
    I have some text laid out using Core Text in my iPhone app. I'm using NSAttributedString to set certain styles within the text for given ranges. I can't seem to find an attribute for setting a background / highlight colour, though it would seem it is possible. I couldn't find an attribute name constant that sounded relevant and the documentation only lists: kCTCharacterShapeAttributeName kCTFontAttributeName kCTKernAttributeName kCTLigatureAttributeName kCTForegroundColorAttributeName kCTForegroundColorFromContextAttributeName kCTParagraphStyleAttributeName kCTStrokeWidthAttributeName kCTStrokeColorAttributeName kCTSuperscriptAttributeName kCTUnderlineColorAttributeName kCTUnderlineStyleAttributeName kCTVerticalFormsAttributeName kCTGlyphInfoAttributeName kCTRunDelegateAttributeName Craig Hockenberry, developer of Twitterrific has said publicly on Twitter that he uses Core Text to render the tweets, and Twitterrific has this background / highlight that I'm talking about when you touch a link. Any help or pointers in the right direction would be fantastic, thanks. Edit: Here's a link to the tweet Craig posted mentioning "Core text, attributed strings and a lot of hard work", and the follow up that mentioned using CTFrameSetter metrics to work out if touches intersect with links.

  • LabVIEW: converting numeric array to string array

    - by JaysonFix
    Using LabVIEW 2009, I have a VI that outputs an array of U64 integers. I'd like the user to be able to perform discrete selection from among the elements of this array. I'm thinking of accomplishing this by programmatically populating a Menu Ring (as shown at http://digital.ni.com/public.nsf/allkb/FB0409491FAB16FA86256D08004FCE7E). However, I apparently need to convert my array of U64 ints to an array of strings, as it is an array of strings that is used to populate the Menu Ring. My question: how can I convert the array of U64 ints to an array of strings?

  • Convert a user's search string into a MS SQL `Full-Text Query` Search Phrase

    - by Atomiton
    I've search for answers for this and I can't seem to find an answer to what should be somewhat simple. This is related to another question I asked, but it's different. What's the best way to take a user's search phrase and throw it into a CONTAINSTABLE(table, column, @phrase, topN ) phrase? Say, for example the user inputs: Books by "Dr. Seuss" What's the best way to turn that into something that will return results in my ContainsTAble() phrase? I was previously parsing the search phrase and writing something like ISABOUT("Books" WEIGHT(1.0), "by" WEIGHT(0.9), "Dr. Seuss" WEIGHT(0.8)) as my @phrase but ISABOUT seems to be returning odd results... especially when one word searches are entered. Any Ideas?

  • Accessing 2D array and passing string to label.text

    - by Amir
    Hi. I'm trying to create 2D array and initialize it with NSStrings. When I try to copy content of a cell from the array to a label.text, the application crashes. NSMutableArray *array = [NSMutableArray arrayWithCapacity:0]; [array addObject:[NSMutableArray arrayWithObjects: [NSArray arrayWithObjects: @"0-0", @"0-1", @"0-2", nil], [NSArray arrayWithObjects: @"1-0", @"1-1", @"1-2", nil], [NSArray arrayWithObjects: @"2-0", @"2-1", @"2-2", nil], nil]]; label.text = [[array objectAtIndex:0] objectAtIndex:0]; Any idea why and what am I doing wrong?

  • convert string to float without silent NaN/Inf conversion

    - by Peter Hansen
    I'd like convert strings to floats using Python 2.6 and later, but without silently converting things like 'NaN' and 'Inf'. Before 2.6, float("NaN") would raise a ValueError. Now it returns a float for which math.isnan() returns True, which is not useful behaviour for my application. Here's what I've got at the moment: import math def get_floats(source): for text in source.split(): try: val = float(text) if math.isnan(val) or math.isinf(val): raise ValueError yield val except ValueError: pass This is a generator, which I can supply with strings containing whitespace-separated sequences representing real numbers. I'd like it to yield only those fields which are purely numeric representations of floats, as in "1.23" or "-34e6", but not for example "NaN" or "-Inf". Test case: assert list(get_floats('1.23 -34e6 NaN -Inf')) == [1.23, -34000000.0] Please suggest alternatives you consider more elegant, even if they involve "look before you leap" (which is normally considered a lesser approach in Python).

  • Mysql Real Escape String PHP Function Adding "\" to My Field Entry

    - by Jascha
    Hello, I am submitting a form to my mySql database using PHP. I am sending the form data through the mysql_real_escape_string($content); function. When the entry shows up in my database (checking in myPhpAdmin) all of my double quotes and single quotes are escaped. I'm fairly certain this is a PHP configuration issue? so: $content = 'Hi, my name is Jascha and my "favorite" thing to do is sleep'; mysql_real_escape_string($content); $query = 'INSERT INTO DB...' comes up in my database as: Hi, my name is Jascha and my \"favorite" thing to do is sleep Who do I tell what to do? (I cannot access the php.ini). -J

  • jQuery RJS inserting string vs dom.

    - by Dmitriy Likhten
    So I am trying to use jQuery to insert data from an ajax call. I actually use the jquery.form plugin, and have the ajax form submitted with a dataType: 'script'. The response is a jquery expression which contains a <%= javascript_escape(render ...) %> erb tag (similar to what the railscasts episode 136 instructs to do). However the end result is that the full text of the render is inserted as if that was the content to be inserted into the page, as text, not as dom elements. Could the fact that the render had some newlines at the beginning be the cause? Dom text: "\n \n &lt;li>....&lt;/li>" I also tried having jQuery just read the response as a script and execute it, and used the prototype-based rjs stuff, same effect, the text is inserted into the dom. Are there any reasons why such a behavior would be experienced? A bit of clarification: My response.js.erb is jQuery("#content").append("<%= escape_javascript(render(:partial => "widgets")) %>"); jQuery("#information").text("Finally, something happened!"); The full text inside the append() call is inserted as text into #content.

  • iPhone link to map directions using string "current location" not lat and lng for saddr

    - by Nick
    I know there are numerous questions about how to construct a sharedApplication link to the maps app specifying the start and end address with coordinates. I've got that working no problem. Has anyone found a way to link with a source address generically specified as "current location". I ask because the scenario I'm working on having Core Location or a UIMapView would only be necessary in order to determine the user location prior to handing off to the map app where the user locating would seem to just happen again. I've tried throwing UTF8'd "Current Location" and "[Current Location]" into the saddr parameter which amusingly starts from Current Montana. I've also tried simply excluding the saddr param. I know this is often tread territory but this particular situation wasn't covered by anything I found searching here or on mapki. Before I add the core location code I just wanted to make sure there wasn't a more limited way to tackle this. Thanks

  • Simple string pattern matching

    - by Joonas Trussmann
    What's the easiest way of doing simple pattern matching a la .something.com something.com/ something.com/somefolder/*.jpg in the iPhone SDK? At this point it looks like I'm going to have to use a regular expression library of some sort, which is really overkill when all I need is simple wildcard matching. None of the standard NSString methods seem to be available on the iPhone.

  • Python mistaking float for string

    - by wrongusername
    I receive TypeError: Can't convert 'float' object to str implicitly while using Gambler.pot += round(self.bet + self.money * 0.1) where pot, bet, and money are all doubles (or at least are supposed to be). I'm not sure if this is yet another Eclipse thing, but how do I get the line to compile? Code where bet and money are initialized: money = 0 bet = 0

  • Comparing values from a string in a MySQL query

    - by bellesebastien
    I'm having some trouble comparing values found in VARCHAR fields. I have a table with products and each product has volume. I store the volume in a VARCHAR field and it's usually a number (30, 40, 200..) but there are products that have multiple volumes and their data is stored separated by semicolons, like so 30;60;80. I know that storing multiple volumes like that is not recommended but I have to work with it like it is. I'm trying to implement a search by volume function for the products. I want to also display the products that have a bigger or equal volume than the one searched. This is not a problem with the products that have a single volume, but it is a problem with the multiple volume products. Maybe an example will make things clearer: Let's say I have a product with this in it's volume field: 30;40;70;80. If someone searched for a volume, lets say 50, I want that product to be displayed. To do this I was thinking of writing my own custom MySQL function (I've never this before) but maybe someone can offer a different solution. I apologize for my poor English but I hope I made my question clear. Thanks.
