Flatten the recursive XML tree

• Flatten the recursive hierarchy

  Hello
  
  I am trying to flatten a recursive hierarchy like this table:
  
  Source:
  
  KEY... PARENT_KEY... NAME... LEVEL
  1 ........... (NULL)................... ABC............ 1
  2 .......... 1...........................123............2
  3 .......... 1...........................456............2
  4 ......... 3...........................xyz............. 3
  
  
  Target:
  
  KEY... NAME_LEVEL1... NAME_LEVEL2... NAME_LEVEL3
  1 ........ ABC...................... ABC...................... ABC
  2 ........ ABC...................... 123, 123
  3 ........ ABC...................... ... 456 456
  4 ........ ABC...................... 456... xyz
  
  
  I tried to use the CONNECT BY clause to flatten out it, but I'm stuck trying to get the third level. Here's my query:
  
  Select name, previous name
  source
  Start with parent_key is null
  connect by prior key = parent_key;
  
  Is it possible to get all the names of level 3 in a single query? Maybe connect you by is the wrong thing to use here?
  
  Thank you

  Hello

  CONNECTION is good for this, because it allows us to use the SYS_CONNECT_BY_PATH:

  SELECT     key
  ,     NVL (REGEXP_SUBSTR (SYS_CONNECT_BY_PATH (name, '/'), '[^/]+', 1, 1), name)     AS name_level_1
  ,     NVL (REGEXP_SUBSTR (SYS_CONNECT_BY_PATH (name, '/'), '[^/]+', 1, 2), name)     AS name_level_2
  ,     NVL (REGEXP_SUBSTR (SYS_CONNECT_BY_PATH (name, '/'), '[^/]+', 1, 3), name)     AS name_level_3
  FROM     source
  START WITH     parent_key     IS NULL
  CONNECT BY     parent_key     = PRIOR key
  ;
  

  This requires that you know some characters that never occurs in the name. I used "/" above, but you can use any character.

  I hope that answers your question.
  If not, post CREATE TABLE and INSERT statements for your sample data, as well as an explanation of how you get the desired results.

• Filter the display of the source xml tree

  I have a treeview control that displays an xml structure.
  
  I have converted the XML into an XMLListCollection and ran a filter but it filters only the parent node, I need to filter the children of the treeview display.
  
  I can make a new xml code from the original that contains only the data I need, but I need information of XML to another window to display when selected. I don't want to just under a tree node.
  
  all ideas
  
  Thank you
  
  

  Yes, I found myself using this excellent datadescriptor
  http://snippets.dzone.com/posts/show/5673
  and change it to use interface XMLListCollection.

  This allows me to specify the node names to use as children, in this example simple visible will be displayed in the tree, invisible are not, but still be accessible in the XML.
  
  
  
  
  

• A loop in the XML tree

  I posted this in the title of the general support Flex under a different title.
  
  What I'm trying to do is to loop through a XML structure that is used as a dataprovider for a menu bar. I couldn't find how to do this. Part of what I've tried so far is;
  
  I think I can get the data in XML format;
  
  MenuData = XML (menuLoad.lastResult);
  
  Once in this format, I was unable to find a way to loop (recursively, I presume) through the children to find the child with the attribute I need.
  
  I looked through the documentation, forums, blogs etc and no one (that I could find) contains an example of how to loop through an XML tree. Here is an example that does not work;
  
  traceNodes (MenuData);
  
  private void traceNodes(theNode:XML):void
  {
  (child var in theNode.)
  {
  trace (Child.Name ());
  trace (Child.Attributes ());
  traceNodes ([child] theNode);
  }
  }
  
  I really need help on this one.

  Roberto:

  Thanks for the post, I was finally able to solve this problem. Here is my function to find a node in an xml tree. You could call it that;

  xmlMyNode = getXMLByAttribute (xmlMytree, "*", "label", "My Label");

  -----------------------------------------------------------

  private void getXMLByAttribute(xmlInputNode:XML,strNodeName:String,strAttribute:String,strAttributeVal_ue:String):XML
  {
  var xmlReturnNode:XML = null;
  for each (var xmlCurrentNode:XML of in xmlInputNode [strNodeName])
  {
  If (xmlCurrentNode.@[strAttribute] == strAttributeValue) return xmlCurrentNode;
  xmlReturnNode = getXMLByAttribute (xmlCurrentNode, strNodeName, strAttribute, strAttributeValue);
  If (xmlReturnNode! = null) break;
  }
  Return xmlReturnNode;
  }

• XML tree in memory after the closure of XmlResults

  Hello
  
  is it possible to have a tree xml parsed in memory that represents objects XmlValue after I closed the corresponding XmlResults. I want to have smth like nu.xom.Document (or any what analogues).
  The closest solution to you, I found so far becomes handle node and then rebuild XmlResults out of it by calling XmlContainer.getNode (java.lang.String). But it's not exactly what I want. I could not have access to the container object, or it might already be closed. The poor alternative is to get a chain of XmlValue.asString () and he feed such as XOM Builder.build (). But it is extremely inefficient.
  Are there better sth in his mind?
  
  P.S. I still want to recover documents lazily, but in the case of a get required an XML tree in memory.
  
  Thank you
  Vyacheslav

  Vyacheslav,

  What you want is coming in the next version of BDB XML. There is a new interface that is (currently) spec'd as:
  XmlResults XmlResults::copyResults()
  It makes a temporary copy of the result set that can be used regardless of the transaction in progress (or container).

• Helps the Parseing XML

  Version: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - Production

  Hello

  I need assistance with an XML file to generate lines to insert into a table staged for further processing.

  There is an XML document that is loaded into a table in the database via a Web Service call.

  I need to query this table to get the XML code, loop through it to create folders, with the fields in a specific order and insert records into a table of staging.

  There are two columns that are not in the XML that are added during the process. I am including these tables as well.

  I know it is a bunch of "stuff", but I hope I've provided enough information to get help.

  Event.CompleteDate

  v_tracking_id

  Event.ProgramRegistrationID

  Event.StartTime

  You have several questions in the XML, so when flattened document you will have several lines trying to extract in v_result.  Where the error.  You will need to either loop

  for rec in (select... from XMLTable...)

  loop

  insert into staging_tbl...

  end loop;

  or make an insert select

  insert into staging_tbl (results_data)

  Select...

  from XMLTable...

• XMLList to the external XML file

  Hi all
  
  I'm new to Flex, but I was impressed with it so far. I was able to create a simple, where things application like navigation trees and the data in the table were populated based on XML stored in tags mx:XMLList inside the main document. To clean things up, I thought that I would like to move the data in external XML files. I copied the data files and verified that the data has always been a single top-level node. Then, noted that mx:XMLList does not support the attribute 'source', so I converted to the use of mx:XML within the application mxml tags. Compiles the application now, but all of the XML hierarchy displayed in the form of a single node, instead of being analyzed in the tree nodes. No idea what I'm missing here? And thanks in advance for the noob easy going. ;-)
  
  -Josh

  Yet once, answered myself for posterity.

  For the tree data, the top node is implied, so I just had to change the dataProvider to {deviceTree.node}. For the data in the table, it was a little more difficult, where rather to link using a tag, I rather linked to it as a and then created a where the source is specified as the {[id XML]. [node]}. (once again the top node was already implicit)

• I created a new library of more new playlists but cannot find the Library.xml file

  Hello

  I'm going to re - build my iTunes files from scratch, a kind of decennial event 'spring clean '. I have created a new library by using the command, click on application startup, and then began to rebuild new reading lists in the application. I can see the folder newly created the library that contains the new "iTunes Library.itl" file BUT I don't see that the iTunes Music Library.xml file. " There certainly must be one to save the data of the playlist, and probably "Get Info" should reflect today date' today... I don't see older versions.

  Although everything seems to work perfectly I don't want to have to re - visit the construction of Playlists from scratch for the next ten years! Can anyone suggest what happened to the .xml file?

  Thanks and greetings

  You can create an .xml on iTunes/file/library/Export library file and gives you the opportunity to put the Library.xml file in your iTunes Media folder - or anywhere you like.

  If you need to rebuild your playlists, you can go to iTunes, file, library, import playlist and select the .xml file.

  Normally, you do not see the .xml file in your iTunes folder.

• "The document is not valid. The index.xml file is missing.

  I suddenly can't open one of my docs of numbers. I get a msg "'name of the doc' document is not valid. The index.xml file is missing.  I literally had the open document this morning without problem, closed, tried to reopen and now I get this msg... all in the same session of the computer. It began not after an update or anything like that, right in the middle of a session of the computer.  You seem to affect all the docs of numbers.  I can't open an any of them now.  I am running OS X El Capitan Version 10.11 and numbers 09, Version 2.1.

  Hi jg,.

  The case usual this message, it is that the document has been opened in numbers version 3.xx, which converts it into a new file version that uses the file index.xml internal requested by Numbers ' 09.

  You have 3 numbers installed on your machine? This file has already been opened in this application?

  The file was saved to iCloud or opened by the iOS version numbers or numbers for iCloud?

  Recommended 'cure' is to open the file using the 3 numbers, then save as... or export to format Numbers ' 09. As a result, remember numbers to quit smoking (v3) - menu numbers > numbers to quit smoking; by clicking on the red light closed the file, but doesn't end numbers. So avoid open numbers files by double-clicking on the file itself.

  Instead, start Numbers ' 09 (v2.3) and open the file in the application.

  Kind regards

• Extracting XML error. The XML file that is assigned in the configuration.xml is either incorrect or damaged.

  This can be caused by a recent update of Flash 11.3.

  See:

  • https://support.Mozilla.org/KB/Flash-113-doesn ' t-charge-video-firefox

• After invoking the RSS "Subscribe to this page", then using the previous/next buttons, Firefox displays the raw XML code

  1) go to the URL http://bionsmalleyassoc.com/BSA_jsp/MU_test
  (2) select Bookmarks-> subscribe to this page
  3) press the previous button
  4) press the next button
  Note that him 'subscribe to this page' does not reappear. However, Firefox incorrectly displays the raw for the RSS XML, as if he forgot that the destination forward is an RSS feed.

  This same sequence in IE9 or Safari 5.1 works fine as expected. In addition, Firefox has the same problem in MAC OSX 10.6

  Works for me now, you probably recharge and bypass the cache (Ctrl + F5) to get a new copy of this page RSS.

• Error message: the index.xml file is missing.

  I am trying to open a 'Numbers' file, which is stored in Dropbox in the cloud.

  I know there are some discussions about this already on this support group but they all suggest to back up files in Time Machine. I use Dropbox for years with no problems, but today I tried to open a file of numbers in Dropbox and received the message: "the index.xml file is missing." I have 2 other computers and an iPhone 6 and the file opens on them perfectly so my problem is with a single computer.

  I tried pulling the file from Dropbox on the desktop of another computer and then send this file to me as an attachment. I opened this file on the computer sends me questions, drag the file on the desktop and when I tried to open the file, I got the same message.

  It's just strange that it will not be open on computers.

  Any advise?

  Thank you, Tony

  Hi Tony,.

  This is somethng that occurs when you try to open a file of 3 numbers to 2 digits ('09). Make sure that you leave 2 numbers and then try to open the file of numbers 3. That should do it.

• The index.xml file required is missing. Cannot open documents. 10.10.5 sys

  The index.xml file required is missing. Cannot open documents. 10.10.5 sys

  You have two versions of installed Pages, where the Pages ' 09 document format use it internal document index.xml, and all Pages v5 releases use a different document format that does not incorporate the index.xml file. If you have Pages ' 09 running without window, and double-click a v5 document Pages, you will get a Pages ' 09 dialog box indicating that the index.xml file is missing.

  Exit Pages ' 09 and then double click on the document to open correctly in your version of v5 Pages.
