traversal

问题 I have a Java Web App running on Tomcat on which I'm supposed to exploit Path traversal vulnerability. There is a section (in the App) at which I can upload a .zip file, which gets extracted in the server's /tmp directory. The content of the .zip file is not being checked, so basically I could put anything in it. I tried putting a .jsp file in it and it extracts perfectly. My problem is that I don't know how to reach this file as a "normal" user from browser. I tried entering ../../../tmp

问题 I think this question has been asked, but I not found anything. From the Document element in Jsoup, how I can traverse for all elements in the HTML content? I was reading the documentation and I was thinking about using the childNodes() method, but it only takes the nodes from one leval below (what I understand). I think I can use some recursion with this method, but I want to know if there is a more appropriate/native way to do this. 回答1: From Document (and any Node subclass), you can use

问题 I have a multidimensional matrix that can have any number of dimensions greater than one. Looking for an efficient algorithm that can visit every point in the matrix. Some info about the code: The matrix has value accessors like (although these aren't really relevant). object value = matrixInstance.GetValue(int[] point); matrixInstance.SetValue(object value, int[] point); Note: Argument point is array of indexes and must match # of dimensions or an exception is thrown. Information about the

问题 I have a CoreData model that can contain an infinite number of children. And I want to display a list of each object, indented for readability like so Object Object first child first childs children first child children Object second child Object 2 Object also has children MOre children Childs Now I come from a PHP background. and in PHP I would create a simple array which Ill traverse with some functions to build this list but this still seems stupidly hard for me. I got a flat array which

问题 I have the following XML code that I'm trying to parse, but I'm sure of how to traverse some of the data in PHP: <entry> <id>http://data.treasury.gov:8001/Feed.svc/DailyTreasuryYieldCurveRateData(5360)</id> <title type="text"></title> <updated>2011-06-09T20:15:18Z</updated> <author> <name /> </author> <link rel="edit" title="DailyTreasuryYieldCurveRateDatum" href="DailyTreasuryYieldCurveRateData(5360)" /> <category term="TreasuryDataWarehouseModel.DailyTreasuryYieldCurveRateDatum" scheme=

问题 If I have a Class like below. How do i traverse through it until its property SomeObjects.count = 0 public class SomeObject { public String Name { get; set; } public List<SomeObject> SomeObjects { get; set; } } Many Thanks 回答1: Here is a generic example of how you can traverse a composite object: public static class TraversalHelper{ public static void TraverseAndExecute<T>(this T composite, Func<T,IEnumerable<T>> selectChildren, Action<T> action) where T: class { action.Invoke(composite);

问题 I'm reading the Cormen algorithms book (binary search tree chapter) and it says that there are two ways to traverse the tree without recursion: using stack and a more complicated but elegant solution that uses no stack but assumes that two pointers can be tested for equality I've implemented the first option (using stack), but don't know how to implement the latter. This is not a homework, just reading to educate myself. Any clues as to how to implement the second one in C#? 回答1: Sure thing.

问题 I would like to select the start and end selector for the prevUntil() or nextUntil() jQuery selector methods. If I implement these methods now, it grabs everything between the two selectors given. i.e. $('p').prevUntil('h1') will not include the p and h1 element, only those between them. How could I also select the p and h1 elements as well as though between? 回答1: Take a look at the .addBack method to add the results of the previous selector to the current matches. Combining that with the

问题 How to traverse each node of a tree efficiently without recursion in C (no C++)? Suppose I have the following node structure of that tree: struct Node { struct Node* next; /* sibling node linked list */ struct Node* parent; /* parent of current node */ struct Node* child; /* first child node */ } It's not homework. I prefer depth first. I prefer no additional data struct needed (such as stack). I prefer the most efficient way in term of speed (not space). You can change or add the member of
