  • xpath help substring expression

    - by NA
    Hi i have a document from which i am trying to extract a date. But the problem is within the node along with the date their is some text too. Something like <div class="postHeader"> Posted on July 20, 2009 9:22 PM PDT </div> From this tag i just want the date item not the Posted on text. something like ./xhtml:div[@class = 'postHeader'] is getting everything. and to be precise, the document i have is basically a nodelist of this elements for eg i will get 10 nodes of these elements with different date values but to be worse the problem is sometime inside these tags some random other tags also pops us like anchors etc. Can i write a universal expath which will just get the date out of the div tag?

  • Auto generation of Web Service sample, help and documentation

    - by orjan
    We're using javax.jws.WebServices deployed in a Glassfish server, is there a way to auto generate documentation like the one ASMX services generates? ASMX services display methods in service ASMX services when running locally could be easily tested with a prebuilt form ASMX services provided a sample request and response XML message http://keithelder.net/blog/archive/2008/01/15/How-to-Get-Around-WCFs-Lack-of-a-Preview-Web.aspx In Glasshfish together with /test/TestApi?wsdl there's /test/TestApi?Tester but it doesn't work, I don't know if it can be used to provide similar features as above?

  • NullPointerException Java help

    - by KP65
    Hello guys. I've been tearing my hair out the past few hours trying to solve this problem. Every time I click on a JButton which should open a JFrame(And it does), i get a stacktrace saying I have a null point exception at these bits of code: In class A i have: aButton.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { B instanceofB = new B(userSession.getBalance()); }); and Class B super.getSomeBtn().setVisible(false); This is where the stacktrace says the errors are in the two above sections. I have a line exactly the same as the one above in Class B and it works fine? Really stuck here!

  • Mutual Information / Entropy Calculation Help

    - by Fillip
    Hi, Hoping someone can give me some pointers with this entropy problem. Say X is chosen randomly from the uniform integer distribution 0-32 (inclusive). I calculate the entropy, H(X) = 32 bits, as each Xi has equal probability of occurring. Now, say the following pseudocode executes. int r = rand(0,1); // a random integer 0 or 1 r = r * 33 + X; How would I work out the mutual information between the two variables r and X? Mutual Information is defined as I(X; Y) = H(X) - H(X|Y) but I don't really understand how to apply the conditional entropy H(X|Y) to this problem. Thanks

  • Help translating Reflector deconstruction into compilable code

    - by code poet
    So I am Reflector-ing some framework 2.0 code and end up with the following deconstruction fixed (void* voidRef3 = ((void*) &_someMember)) { ... } This won't compile due to 'The right hand side of a fixed statement assignment may not be a cast expression' I understand that Reflector can only approximate and generally I can see a clear path but this is a bit outside my experience. Question: what is Reflector trying to describe to me? Update: Am also seeing the following fixed (IntPtr* ptrRef3 = ((IntPtr*) &this._someMember)) Update: So, as Mitch says, it is not a bitwise operator, but an addressOf operator. Question is now: fixed (IntPtr* ptrRef3 = &_someMember) fails with an 'Cannot implicitly convert type 'xxx*' to 'System.IntPtr*'. An explicit conversion exists (are you missing a cast?)' compilation error. So I seemed to be damned if I do and damned if I dont. Any ideas?

  • help me reason about F# threads

    - by Kevin Cantu
    In goofing around with some F# (via MonoDevelop), I have written a routine which lists files in a directory with one thread: let rec loop (path:string) = Array.append ( path |> Directory.GetFiles ) ( path |> Directory.GetDirectories |> Array.map loop |> Array.concat ) And then an asynchronous version of it: let rec loopPar (path:string) = Array.append ( path |> Directory.GetFiles ) ( let paths = path |> Directory.GetDirectories if paths <> [||] then [| for p in paths -> async { return (loopPar p) } |] |> Async.Parallel |> Async.RunSynchronously |> Array.concat else [||] ) On small directories, the asynchronous version works fine. On bigger directories (e.g. many thousands of directories and files), the asynchronous version seems to hang. What am I missing? I know that creating thousands of threads is never going to be the most efficient solution -- I only have 8 CPUs -- but I am baffled that for larger directories the asynchronous function just doesn't respond (even after a half hour). It doesn't visibly fail, though, which baffles me. Is there a thread pool which is exhausted? How do these threads actually work?

  • Help with cake controllers

    - by adam
    We had an outsourced engineer work on a quick feature DELETING items listed in our database. He says that the code is difficult because the "controller" is missing. Is there a pre-loaded controller for every function like that in cake, or is it weird that he is expecting a controller to be there for a feature we didn't have yet.

  • Help to convert PostgreSQL dates into SQL Server dates

    - by Earlz
    Hello I'm doing some data conversion from PostgreSQL to Microsoft SQL Server. So far it has all went well and I almost have the entire database dump script running. There is only one thing that is now messed up: dates. The dates are dumped to a string format. These are two example formats I've seen so far: '2008-01-14 12:00:00' and the more precise '2010-04-09 12:23:45.26525' I would like a regex (or set of regexs) that I could run so that will replace these with SQL Server compatible dates. Anyone know how I can do that?

  • Mysql - help me optimize this query (improved question)

    - by sandeepan-nath
    About the system: - There are tutors who create classes and packs - A tags based search approach is being followed.Tag relations are created when new tutors register and when tutors create packs (this makes tutors and packs searcheable). For details please check the section How tags work in this system? below. Following is the concerned query SELECT SUM(DISTINCT( t.tag LIKE "%Dictatorship%" )) AS key_1_total_matches, SUM(DISTINCT( t.tag LIKE "%democracy%" )) AS key_2_total_matches, COUNT(DISTINCT( od.id_od )) AS tutor_popularity, CASE WHEN ( IF(( wc.id_wc > 0 ), ( wc.wc_api_status = 1 AND wc.wc_type = 0 AND wc.class_date > '2010-06-01 22:00:56' AND wccp.status = 1 AND ( wccp.country_code = 'IE' OR wccp.country_code IN ( 'INT' ) ) ), 0) ) THEN 1 ELSE 0 END AS 'classes_published', CASE WHEN ( IF(( lp.id_lp > 0 ), ( lp.id_status = 1 AND lp.published = 1 AND lpcp.status = 1 AND ( lpcp.country_code = 'IE' OR lpcp.country_code IN ( 'INT' ) ) ), 0) ) THEN 1 ELSE 0 END AS 'packs_published', td . *, u . * FROM tutor_details AS td JOIN users AS u ON u.id_user = td.id_user LEFT JOIN learning_packs_tag_relations AS lptagrels ON td.id_tutor = lptagrels.id_tutor LEFT JOIN learning_packs AS lp ON lptagrels.id_lp = lp.id_lp LEFT JOIN learning_packs_categories AS lpc ON lpc.id_lp_cat = lp.id_lp_cat LEFT JOIN learning_packs_categories AS lpcp ON lpcp.id_lp_cat = lpc.id_parent LEFT JOIN learning_pack_content AS lpct ON ( lp.id_lp = lpct.id_lp ) LEFT JOIN webclasses_tag_relations AS wtagrels ON td.id_tutor = wtagrels.id_tutor LEFT JOIN webclasses AS wc ON wtagrels.id_wc = wc.id_wc LEFT JOIN learning_packs_categories AS wcc ON wcc.id_lp_cat = wc.id_wp_cat LEFT JOIN learning_packs_categories AS wccp ON wccp.id_lp_cat = wcc.id_parent LEFT JOIN order_details AS od ON td.id_tutor = od.id_author LEFT JOIN orders AS o ON od.id_order = o.id_order LEFT JOIN tutors_tag_relations AS ttagrels ON td.id_tutor = ttagrels.id_tutor JOIN tags AS t ON ( t.id_tag = ttagrels.id_tag ) OR ( t.id_tag = lptagrels.id_tag ) OR ( t.id_tag = wtagrels.id_tag ) WHERE ( u.country = 'IE' OR u.country IN ( 'INT' ) ) AND CASE WHEN ( ( t.id_tag = lptagrels.id_tag ) AND ( lp.id_lp 0 ) ) THEN lp.id_status = 1 AND lp.published = 1 AND lpcp.status = 1 AND ( lpcp.country_code = 'IE' OR lpcp.country_code IN ( 'INT' ) ) ELSE 1 END AND CASE WHEN ( ( t.id_tag = wtagrels.id_tag ) AND ( wc.id_wc 0 ) ) THEN wc.wc_api_status = 1 AND wc.wc_type = 0 AND wc.class_date '2010-06-01 22:00:56' AND wccp.status = 1 AND ( wccp.country_code = 'IE' OR wccp.country_code IN ( 'INT' ) ) ELSE 1 END AND CASE WHEN ( od.id_od 0 ) THEN od.id_author = td.id_tutor AND o.order_status = 'paid' AND CASE WHEN ( od.id_wc 0 ) THEN od.can_attend_class = 1 ELSE 1 END ELSE 1 END GROUP BY td.id_tutor HAVING key_1_total_matches = 1 AND key_2_total_matches = 1 ORDER BY tutor_popularity DESC, u.surname ASC, u.name ASC LIMIT 0, 20 The problem The results returned by the above query are correct (AND logic working as per expectation), but the time taken by the query rises alarmingly for heavier data and for the current data I have it is like 25 seconds as against normal query timings of the order of 0.005 - 0.0002 seconds, which makes it totally unusable. It is possible that some of the delay is being caused because all the possible fields have not yet been indexed. The tag field of tags table is indexed. Is there something faulty with the query? What can be the reason behind 20+ seconds of execution time? How tags work in this system? When a tutor registers, tags are entered and tag relations are created with respect to tutor's details like name, surname etc. When a Tutors create packs, again tags are entered and tag relations are created with respect to pack's details like pack name, description etc. tag relations for tutors stored in tutors_tag_relations and those for packs stored in learning_packs_tag_relations. All individual tags are stored in tags table. The explain query output:- Please see this screenshot - http://www.test.examvillage.com/Explain_query.jpg

    Hello, given the following structure: struct nmslist_elem_s { nmptr data; struct nmslist_elem_s *next; }; typedef struct nmslist_elem_s nmslist_elem; Where: typedef void* nmptr; Is it possible to write a MACRO that retrieves the data from the element and cast it to the right type: MACRO(type, element) that expands to *((type*)element->data). For example for int, i would need something like this: *((int*)(element->data)) .

  • Help with use of .NET Generics/Dictionary in replacing my Arrays

    - by Rollo R
    Hello, I have these code: Mypage.cs string[] strParameterName = new string[2] {"?FirstName", "?LastName"}; string[] strParameterValue = new string[2] {"Josef", "Stalin"}; MyConnection.MySqlLink(strConnection, strCommand, strParameterName, strParameterValue, dtTable); Myclass.cs public static void MySqlLink(string strConnection, string strCommand, string[] strParameterName, string[] strParameterValue, DataTable dtTable) { dtTable.Clear(); MySqlConnection MyConnection = new MySqlConnection(strConnection); MySqlCommand MyCommand = new MySqlCommand(strCommand, MyConnection); for (int i = 0; i < strParameterName.Length; i++) { MyCommand.Parameters.AddWithValue(strParameterName[i].ToString(), strParameterValue[i].ToString()); } MySqlDataAdapter MyDataAdapter = new MySqlDataAdapter(MyCommand); MyDataAdapter.Fill(dtTable); } And then my Sql Command will be something like "SELECT * FROM MyTable WHERE FirstName=?FirstName AND LastName=?LastName" As you can see, I am using arrays for the Parameter Name and Parameter Value and they both have to "match" with each other and ofcourse the Sql Command. Someone recommended to me that I use .NET "Dictionary" instead of arrays. Now I have never used that before. Can someone show me a relative example of how I am to use .NET Dictionary here?

  • Android: Help with tabs view

    - by James
    So I'm trying to build a tabs view for an Android app, and for some reason I get a force close every time I try to run it on the emulator. When I run the examples, everything shows fine, so I went as far as to just about copy most of the layout from the examples(a mix of Tabs2.java and Tabs3.java), but for some reason it still wont run, any ideas? Here is my code(List1.class is a copy from the examples for testing purposes). It all compiles fine, just gets a force close the second it starts: package com.jvavrik.gcm; import android.app.TabActivity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.TabHost; import android.widget.TextView; public class GCM extends TabActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); final TabHost tabHost = getTabHost(); tabHost.addTab(tabHost.newTabSpec("tab1") .setIndicator("g", getResources().getDrawable(R.drawable.star_big_on)) .setContent(new Intent(this, List1.class))); tabHost.addTab(tabHost.newTabSpec("tab2") .setIndicator("C") .setContent(new Intent(this, List1.class)) ); tabHost.addTab(tabHost.newTabSpec("tab3") .setIndicator("S") .setContent(new Intent(this, List1.class)) ); tabHost.addTab(tabHost.newTabSpec("tab4") .setIndicator("A") .setContent(new Intent(this, List1.class)) ); } }
