  • div automatically added in $item->get_description(); using simplepie

    - by Carey Estes
    I am getting a div that is appearing in the output from calling a RSS feed. It is ignoring my attempts to wrap it in a paragraph tag and pushes the data out to the div. foreach ($feed->get_items(0 , 3) as $item): $feedDescription = $item->get_content(); $image = returnImage($feedDescription); $image = scrapeImage($image); $image_url= $item->get_permalink(); $description = $item->get_description(); ?> <div class="item"> <h4><a href="<?php echo $item->get_permalink(); ?>"><?php echo $item->get_title(); ?></a></h4> <div class="image-box"><?php echo '<a href="' . $image_url . '"><img src="' . $image . '" /></a>'."\n";?></div> <p><?php echo $description ?></p> <p><a href="<?php echo $item->get_permalink(); ?>">Continue Reading</a></p> </div> <?php endforeach; ?> Here is the html output: <div class="item"> <h4><a href="#">Lorem Ipsum</a></h4> <div class="image-box"><a href="#"><img src="image.jpg"></a> </div> <p></p> <div>Lorem Ipsum description [...]</div> <p></p> <p><a href="#">Continue Reading</a></p> </div> Why does the description call add a div tag and not get wrapped in the paragraph tag?

  • c# Regex on XML string handler

    - by Dan Sewell
    Hi guys. Trying to fiddle around with regex here, my first attempt. Im trying to extract some figures out of content from an XML tag. The content looks like this: www.blahblah.se/maps.aspx?isAlert=true&lat=51.958855252721&lon=-0.517657021473527 I need to extract the lat and long numerical vales out of each link. They will always be the same amount of characters, and the lon may or may not have a "-" sign. I thought about doing something like this below: (The string in question is in the "link" tag): var document = XDocument.Load(e.Result); if (document.Root == null) return; var events = from ev in document.Descendants("item1") select new { Title = (ev.Element("title").Value), Latitude = Regex.xxxxxxx(ev.Element("link").Value, @"lat=(?<Lat>[+-]?\d*\.\d*)", String.Empty), Longitude = Convert.ToDouble(ev.Element("link").Value), }; foreach (var ev in events) { do stuff } Many thanks!

  • Redirects in RoR: Which one to use?

    - by scrr
    Hello, we are making a website that takes a generated incoming link and forwards the user who is clicking on it to another website while saving a record of the action in our DB. I guess it's basically what ad-services like AdSense do. However, what is the best way to redirect the user? I think html-meta-tag-redirects are out of question. So what other options are there? head :moved_permanently, :location => "http://www.domain.com/" This one is a 301-redirect. The next one is a 302: redirect_to "http://www.domain.com" Are there any others? And which is best to use for our case? The links are highly-dynamic and change all the time. We want to make sure we don't violate any existing standards and of course we don't want search-engines to tag us as spammers (which we are not, btw). Thanks!

  • itemdoubleclick event in ExtJS Charts

    - by Abdel Olakara
    Hi all, I got a strange issue today while working on ExtJS charts. I am trying to use some of the events for the chart when user clicks on the chart items. I found the following events are available: itemclick, itemdoubleclick, itemdrag, itemdragstart, itemdragend, itemmouseover, itemmouseout Here is my test chart where I have implemented all these events. Each event just create a list tag in my debuging console. The issue is, no matter what, itemdoubleclick do not get fired! what is the issue? Why is it not getting fired? xtype:'columnchart', width:600, height:350, id:'myChart', store: store, xField: 'month', yField: 'sales', listeners: { itemdoubleclick: function(o) { var dh = Ext.DomHelper; dh.append('consoleList', {tag: 'li', html: 'itemdoubleclick'}); } } In firebug console, I see that this event is registered. PS: In my code above, I have put only the event that is not working. Thanks in advance for your ideas and suggestions.

  • Android WebView not respecting scaling percentage...

    - by fiXedd
    I have a WebView which I'm trying to have scale to a certain percent on loading the page. The iPhone version of this software uses the HTML meta-tag: <meta name="viewport" content="width=320, initial-scale=0.95, maximum-scale=2.0, user-scalable=1"> Since Android's WebView doesn't seem to respect that tag I hard-coded the percent using setInitialScale(). However, the WebView is just flat-out ignoring this method call. No matter what number I put in there it shows at 100%. Ideas?

  • How to handle the browsers who don't support HTML5/CSS3

    - by Sheikh Aman
    Hi, I have been looking into HTML5 and CSS3 and have been liking it quite a lot. Got around the modernizr API, but am stuck at one point, and that leads to further confusions: How will I write a code that caters to the situation of non-compatibility between browsers ? This leads to the following confusions: if I write the doctype as <!DOCTYPE HTML> and my page is accessed in IE6, then ho IE6 will handle the page? If I try to include <video> tag and the page is again accessed by IE6/IE7IE8 (which don't support this tag), Then how am I supposed to be rolling back to flash for them? Should I use some JS to show/hide the content appropriately? I would love to hear some thoughts of you guys. If needed, please mark this post as a community wiki. Thanks!

  • How to make firefox to spellcheck in multiple languages simultaneously?

    - by Vi
    I want to it to assume that text may be in mixture of languages and words should be looked up in multiple dictionaries. (E.g. everything in en-GB, en-US, ru, be and be-classic should be consider as good, everything else should be underlined and corrections from all dictionaries should be offered). Is there an add-on for "multi-language spell-check"? Alternatively, can I merge all dictionaries into one big combined dictionary?

  • Huge file in Clojure and Java heap space error

    - by trzewiczek
    I posted before on a huge XML file - it's a 287GB XML with Wikipedia dump I want ot put into CSV file (revisions authors and timestamps). I managed to do that till some point. Before I got the StackOverflow Error, but now after solving the first problem I get: java.lang.OutOfMemoryError: Java heap space error. My code (partly taken from Justin Kramer answer) looks like that: (defn process-pages [page] (let [title (article-title page) revisions (filter #(= :revision (:tag %)) (:content page))] (for [revision revisions] (let [user (revision-user revision) time (revision-timestamp revision)] (spit "files/data.csv" (str "\"" time "\";\"" user "\";\"" title "\"\n" ) :append true))))) (defn open-file [file-name] (let [rdr (BufferedReader. (FileReader. file-name))] (->> (:content (data.xml/parse rdr :coalescing false)) (filter #(= :page (:tag %))) (map process-pages)))) I don't show article-title, revision-user and revision-title functions, because they just simply take data from a specific place in the page or revision hash. Anyone could help me with this - I'm really new in Clojure and don't get the problem.

  • How to perform COUNT() or COUNT(*)

    - by ninumedia
    I have a list of tags in a database. Ex: villan hero spiderman superman superman I wanted to obtain a sorted list of the tag names in ascending order and the number of times the unique tag appeared in the database. I wrote this code: Ex: SELECT hashtag.tag_name, COUNT( * ) AS number FROM hashtag GROUP BY hashtag.tag_name ORDER BY hashtag.tag_name ASC This yields the correct result: hero - 1 spiderman - 1 superman - 2 villan - 1 How can I obtain the full COUNT of this entire list. The answer should be 4 in this case because there are naturally 4 rows. I can't seem to get a correct COUNT() without the statement failing. Thanks so much for the help! :)

  • What does LAME text does in MP3 file?

    - by Dims
    I see here http://en.wikipedia.org/wiki/MP3 that MP3 file consists of MP3 headers interchanged with MP3 data. MP3 header consist of few bytes. But here is my MP3 file dump with ID3 tag cut. Header is highlighted with blue. You can see that "LAME3.96" text is highlighted with green. What does it does there? Is this a part of MP3 elementary stream? Or this is the part of some headers I didn't tag?

  • Wordpress Taxonomy

    - by ninusik
    I am creating a Wordpress blog (no live link yet because it's still at a planning stage). I want to set up the following tag structure: Category 1: Services Tags: Web design, logo design, print design, etc etc. Category 2: Type of clients Tags: small businesses, large companies So each post will be tagged with one or more tags from Category 1, and one tag from Category 2. However, I heard that using more than one Category per post is a bad idea in terms of SEO? But then, how can I go about it? I don't want any SEO penalties, but I will need to somehow categorize each post using these 2 distinct categories. Should I create some custom taxonomies? That seems like an overkill to me. The solution is probably something rather simple but it just escapes me. I'm not very experienced with taxonomies so I'll appreciate any suggestions.

  • Missunderstanding js variables

    - by meo
    I have a little problem: slideHelpers.total = 4 for (i=1;i <= slideHelpers.total; i++) { $('<a href="#">' + i + '</a>').bind('click', function(){ alert('go to the ' + i + ' slide')}).appendTo('.slideaccess') } the alert gives out 5 what is logic, because when the function click triggers i is actually 5. But i would like to have the same i as in my <a> tag. What is the best way to handle this? I could put i in the data() of the <a> tag for example but i am sure there is a easier way.

  • NSLinguisticTagger on the contents of an NSTextStorage- crashing bug

    - by Remy Porter
    I'm trying to use an NSLinguisticTagger to monitor the contents of an NSTextStorage and provide some contextual information based on what the user types. To that end, I have an OverlayManager object, which wires up this relationship: -(void) setView:(NSTextView*) view { _view = view; _layout = view.layoutManager; _storage = view.layoutManager.textStorage; //get the TextStorage from the view [_tagger setString:_storage.string]; //pull the string out, this grabs the mutable version [self registerForNotificationsOn:self->_storage]; //subscribe to the willProcessEditing notification } When an edit occurs, I make sure to trap it and notify the tagger (and yes, I know I'm being annoyingly inconsistent with member access, I'm rusty on Obj-C, I'll fix it later): - (void) textStorageWillProcessEditing:(NSNotification*) notification{ if ([self->_storage editedMask] & NSTextStorageEditedCharacters) { NSRange editedRange = [self->_storage editedRange]; NSUInteger delta = [self->_storage changeInLength]; [_tagger stringEditedInRange:editedRange changeInLength:delta]; //should notify the tagger of the changes [self highlightEdits:self]; } } The highlightEdits message delegates the job out to a pool of "Overlay" objects. Each contains a block of code similar to this: [tagger enumerateTagsInRange:range scheme:NSLinguisticTagSchemeLexicalClass options:0 usingBlock:^(NSString *tag, NSRange tokenRange, NSRange sentenceRange, BOOL *stop) { if (tag == PartOfSpeech) { [self applyHighlightToRange:tokenRange onStorage:storage]; } }]; And that's where the problem is- the enumerateTagsInRange method crashes out with a message: 2014-06-04 10:07:19.692 WritersEditor[40191:303] NSMutableRLEArray replaceObjectsInRange:withObject:length:: Out of bounds This problem doesn't occur if I don't link to the mutable copy of the underlying string and instead do a [[_storage string] copy], but obviously I don't want to copy the entire backing store every time I want to do tagging. This all should be happening in the main run loop, so I don't think this is a threading issue. The NSRange I'm enumerating tags on exists both in the NSTextStorage and in the NSLinguisticTagger's view of the string. It's not even the fact that the applyHighlightToRange call adds attributes to the string, because it crashes before even reaching that line. I attempted to build a test case around the problem, but can't replicate it in those situations: - (void) testEdit { NSAttributedString* str = [[NSMutableAttributedString alloc] initWithString:@"Quickly, this is a test."]; text = [[NSTextStorage alloc] initWithAttributedString:str]; NSArray* schemes = [NSLinguisticTagger availableTagSchemesForLanguage:@"en"]; tagger = [[NSLinguisticTagger alloc] initWithTagSchemes:schemes options:0]; [tagger setString:[text string]]; [text beginEditing]; [[text mutableString] appendString:@"T"]; NSRange edited = [text editedRange]; NSUInteger length = [text changeInLength]; [text endEditing]; [tagger stringEditedInRange:edited changeInLength:length]; [tagger enumerateTagsInRange:edited scheme:NSLinguisticTagSchemeLexicalClass options:0 usingBlock:^(NSString *tag, NSRange tokenRange, NSRange sentenceRange, BOOL *stop) { //doesn't matter, this should crash }]; } That code doesn't crash.

  • What are the common programming mistakes in Python?

    - by Paul McGuire
    I was about to tag the recent question in which the OP accidentally shadowed the builtin operator module with his own local operator.py with the "common-mistakes" tag, and I saw that there are a number of interesting questions posted asking for common mistakes to avoid in Java, Ruby, Scala, Clojure, .Net, jQuery, Haskell, SQL, ColdFusion, and so on, but I didn't see any for Python. For the benefit of Python beginners, can we enumerate the common mistakes that we have all committed at one time or another, in the hopes of maybe steering a newbie or two clear of them? (In homage to "The Princess Bride", I call these the Classic Blunders.) If possible, a little supporting explanation on what the problem is, and the generally accepted resolution/workaround, so that the beginning Pythoner doesn't read your answer and say "ok, that's a mistake, how do I fix it?"

  • Android Couchdb - libcouch and IPC Aidl Services

    - by dirtySanchez
    I am working on a native CouchdDB app with android. Now just this week CouchOne released libcouch, described as "Library files needed to interact with CouchDB on Android": couchone_libcouch@Github It is a basic app that installs CouchDB if the CouchDB service (that comes with CouchDB if it was installed previously) can't be bound to. To be more precise, as I understand it: libcouch estimates CouchDb's presence on the device by trying to bind to a IPC Service from CouchDB and through that service wants communicate with CouchDB. Please see the method "attemptLaunch()" at CouchAppLauncher.class for reviewing this: public void attemptLaunch() { Log.i(TAG,"1.) called attemptLaunch"); Intent intent = new Intent(ICouchService.class.getName()); Log.i(TAG,"1.a) setup Intent"); Boolean canStart = bindService(intent, couchServiceConn, Context.BIND_AUTO_CREATE); Log.i(TAG,"1.b bound service. canStart: " + Boolean.toString(canStart)); if (!canStart) { setContentView(R.layout.install_couchdb); TextView label = (TextView) findViewById(R.id.install_couchdb_text); Button btn = (Button) this.findViewById(R.id.install_couchdb_btn); String text = getString(R.string.app_name) + " requires Apache CouchDB to be installed."; label.setText(text); // Launching the market will fail on emulators btn.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { launchMarket(); finish(); } }); } } The question(s) I have about this are: libcouch never is able to "find" a previously installed CouchDB. It always attempts to install CouchDB from the market. This is because it never actually is able to bind to the CouchDBService. As I understand the purpose auf AIDL generated service interfaces, the actual service that intends to offer it's IPC to other applications should make use of AIDL. In this case the AIDL has been moved to the application that is trying to bind to the remote service, which is libcouch in this case. Reviewing the commits the AIDL files have just been moved out of that repository to libcouch. For complete linkage, here's the link to the Android CouchDB sources: github.com/couchone/libcouch-android Now, I could be completely wrong in my findings, it could also be lincouch's Manifest that s missing something, but I am really looking forward to get some answers!
