selector

I need to find all places in a bunch of HTML files, that lie in following structure (CSS): div.a ul.b or XPath: //div[@class="a"]//div[@class="b"] grep doesn't help me here. Is there a command-line tool that returns all files (and optionally all places therein), that match this criterium? I.e., that returns file names, if the file matches a certain HTML or XML structure. Dave Jarvis Try this: Install http://www.w3.org/Tools/HTML-XML-utils/ . Save a web page (call it filename.html). Run: hxnormalize -l 240 -x filename.html | hxselect -s '\n' -c "label.black" Where "label.black" is the CSS

I'm struggling to make an alert come up when an anchor tag with a specific class is clicked inside of a div. My html section in question looks like this... <div id="foo"> <a class='bar' href='#'>Next</a> </div> The jQuery section is as follows.. $('.bar').click(function() { alert("CLICKED"); }); My problem is that I cannot get this alert to come up, I think that I'm properly selecting the class "next", but it won't pick it up for some reason. I've also tried almost everything on this page but nothing is working. If I don't try to specify the anchor tag i.e. $('#foo').click(function()... then

On the default ListViews if you long press on an item the background fades from dark blue to light blue(on Galaxy Tab. Its orange to light orange on some other devices) during the time it takes to register a LongClick. I am assuming this is done somehow with a selector but thus far I've only seen how to use selectors for state:selected, state:focused, and state:pressed. This page doesn't seem to show anything about a LongClick state so perhaps my assumption that this is accomplished with a selector is incorrect? Can anyone fill me in on how the default ListView gets this effect and how I can

Is there a way to store a selector in an NSDictionary , without storing it as an NSString ? SEL is just a pointer, which you could store in an NSValue : NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys: [NSValue valueWithPointer:@selector(foo)], @"foo", nil]; To get the selector back, you can use: SEL aSel = [[dict objectForKey:@"foo"] pointerValue]; An alternative to Georg's solution would be to convert the selector into an NSString before storing it the NSDictionary: NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys: NSStringFromSelector(@selector(foo)), @"foo",

does anybody know if it is possible to cancel already queued selector events from the event stack or timer stack (or whatever mechanism it is that is utilized by the API) when you call performSelector:withObject:afterDelay ? I was using this event stack to alter the attributes of an image within a TabBar tab, and would sometimes queue up to 10 seconds worth of changes in one quickly executed for loop... maybe 5 milliseconds or so. the problem arises if the user switches tabs... like say I have the image alterations queued for an image that is displayed as soon as Tab #4 is enabled, and then

Ok very quick question. I am adding annotations to my iOS using MKMapAnnotation. I create a int and an annotation with a disclosure button Which calls the method loadPano like so: int integervariable; [disclosureButton addTarget:self action:@selector(loadPano) forControlEvents:UIControlEventTouchUpInside]; Now say I want to access the integer variable in the method load pano how would I do this, I am struggling to understand how I would pass the variable to the new method when it is called like the above. ehope If you just have to pass an integer associated to each disclosurebutton, you can
