问题 Using XSLT 2.0 and Apache FOP I want to be able to create a new variable, have unique and sorted values inside it by category but preserve the nodes. So the new variable should have the following nodes: <category>1. First Aid</category> <category>2. Access control</category> <category>3. Fire safety</category> <category>4. Recognition</category> The input XML is the following: <equipment> <E0132> <category>1. First Aid</category> <description>Lorem ipsum dolor sit amet, consectetur adipiscing

问题 I'm running a query on three columns; one column contains text, the other two contain numbers. I do a calculation on these numbers to get a new number called $average. I then spit out the result to an html table. The rows in the table are sorted in the order they come out of the database. I'm trying to sort the table so that the data is displayed from highest $average to lowest (while still be correctly associated with the correct text value from the first column). I've tried some asort and

问题 Hi all: Now I have a 3G bytes tomcat access log named urls, each line is a url. I want to count each url and sort these urls order by the number of each url. I did it this way: awk '{print $0}' urls | sort | uniq -c | sort -nr >> output But it took really long time to finish this job, it's already took 30 minutes and its still working. log file is like bellow: /open_api/borrow_business/get_apply_by_user /open_api/borrow_business/get_apply_by_user /open_api/borrow_business/get_apply_by_user

问题 I am facing a problem with array sorting. I am trying to sort an array, but not getting the result as expected. If I want to sort when the count are the same, they also get sorted by price. What's wrong with my approach? self.array = items.sorted(by: { (item1, item2) -> Bool in if item1.count > item2.count { return true } else { if item1.count == item2.count { if item1.price > item2.price { return true } } } return false }) this is my sort result: [Item(name: "AAA", count: 7, price: "30737517

问题 This is a sort of self-imposed extra credit problem I'm adding to my current programming assignment which I finished a week early. The assignment involved reading in integers from a file with multiple integers per line, each separated by a space. This was achieved easily using while(inFile >> val) . The challenge I put myself up to was to try and read integers from a file of mixed numbers and letters, pulling out all contiguous digits as separate integers composed of those digits. For

问题 Need to sort second nested array by a value n the third with php; 'Start Time'. Thinking maybe usort is the key.
