• How to merge 2 XML streams in Java by XSLT

  - by user327933

  I'd like to merge 2 XML streams (strings) in Java, necessarily by XSLT (that I could change the transformation), but the problem is that the XMLs come as a string. There are many examples, but through the files. Can this be done without saving them in files? Thanks.

• What's the difference between C and C++

  - by Dinah

  I know that C++ has the concept of objects but C doesn't. I also know that pretty much all there is to know about C fits into K & R but the C++ library is vastly more complex. There have got to be other big differences though. What are the major differences between C and C++?

  - by Raj Aththanayake

  Hi Both do the same thing. What is the most efficient way to compare two strings? Equals() or Compare()? Are there any differences? if (String.Equals(StringA, StringB, StringComparison.OrdinalIgnoreCase)) { // Your code goes here } if (String.Compare(StringA, StringB, true) == 0) { // Your code goes here }

• How can I find the boundaries of a subset of a sorted list?

  - by Alex

  I have the following dilemma: I have a list of strings, and I want to find the set of string which start with a certain prefix. The list is sorted, so the naive solution is this: Perform binary search on the prefixes of the set, and when you find an element that starts with the prefix, traverse up linearly until you hit the top of the subset. This runs in linear time, however, and I was wondering if anyone can suggest a more efficient way to do it.

• Should multiple regional websites all use the same database?

  - by John Himmelman

  I'm developing a cms for a company that has multiple regional sites (us, uk, china, russia, etc..). Should I use a separate database for each of these sites or use a single database with a 'site' field in each table? My main concern is the table language encoding (ie, can storing strings in different langauges in the same table cause problems, such as sorting issues).

• How to get a random node from a tree?

  - by ooboo

  It looks easy, but I found the implementation tricky. I need that for a simple genetic programming problem I'm trying to implement. The function should, given a node, return the node itself or any of its children such that the probability of choosing a node is normally distributed relative to its depth (so the function should return mostly middle nodes, but sometimes the root itself or the lowest ones - but that's not really necessary if that makes it significantly more complex, if all any node is chosen with equal probability, that's good enough). Thanks

• standard c library for escaping a string.

  - by rampion

  Is there a standard C library function to escape C-strings? For example, if I had the C string: char example[] = "first line\nsecond line: \"inner quotes\""; And I wanted to print "first line\nsecond line: \"inner quotes\"" Is there a library function that will do that transformation for me? Rolling my own just seems a little silly. Bonus points if I can give it a length to escape (so it stops before or beyond the \0).

• AS3: why is this happening?

  - by Bin Chen

  Hi, I just encounter a strange problem: var a:ClassA = new ClassA; var b:ClassA = a; The program keeps running sometime, the a = null, b = null. The program is a complex one, I am sure that no part will touch a, and b. My question is, will the runtime(garbage collector) to collect the memory of "a" and then assign a and b to null? I am confused, thanks!

• "Slice" out one element from a python dictionary

  - by BCS

  I have a dictionary: D = { "foo" : "bar", "baz" : "bip" } and I want to create new dictionary that has a copy of one of it's elements k. So if k = "baz": R = { "baz" : "bip" } what I'v got now is: R = { k : D[k] } But in my case k is a complex expression and I've got a whole stack of these. Caching k in a temporary looks about as ugly as the original option. What I'm looking for is a better (cleaner) way to do this.

• Which kind of changes can't I do with lightweight migration in Core Data?

  - by dontWatchMyProfile

  I recently tried a lot of different stuff with lightweight migration. These all work: 1) Rename attributes (with renaming identifier specified) 2) Add attributes 3) Add new entity + new attribute + inverse relationship to an already existing entity 4) remove existing entity + relationships to that entity = It almost looks like just about anything can be handled with LM. Did I miss something? In which cases am I getting into trouble and need an some more complex approach?
