Comparing nodes in two xml files

• My event.result may or may not return a node in the xml file. How can I avoid that TypeError: Error #1009:

  My event.result may or may not return a node in the xml file. How can I avoid that TypeError: Error #1009: cannot access a property or method of a null object reference.

  I have a very simple question. I want to take the value of

  Event.Result.Item.nodeindex1.nodeindex2.Row.MyValue;

  and assign it to a text field

  mytextTi.text = event.result.item.nodeindex1.nodeindex2.row.myvalue;

  But if a part of the tree is missing, which is also valid, so I get TypeError: Error #1009: cannot access a property or method of a null object reference.

  I tried various solutions such as the following. Is there any simple way to do this?

  If (event.result.item.nodeindex1.nodeindex2.row.myvalue! = undefined)-does not work

  Unfortunately, one must test all levels to ensure that it is not null before the reference to it. You can take advantage of the short-circuit evaluation in tying together, for example

  if (event.result.item
      && event.result.item.nodeindex1
      && event.result.item.nodeindex1.nodeindex2
      && event.result.item.nodeindex1.nodeindex2.row
      && event.result.item.nodeindex1.nodeindex2.row.myvalue)
  {
      // access the variable
  }
  else
  {
      // one of the XML nodes in the path is null
  }
  

  Or you could stay away from her a little hacky and wrap the reference in a try/catch block.

• Retrieve / search a specific node of the XML file

  Hello
  
  I have a question about reading the XML (search) in PL SQL file:
  
  There is an XML file with the following structure:
  

  <root>
    <Hnode1 attr1="value1" />
    <Hnode2 attr1="value1" /> 
       <node1_of_Hnode2 id="10" personname="Steven"/>
       <node2_of_Hnode2 id="20" personname="Christian"/>
       <node3_of_Hnode2 id="30" personname="Arnold"/>
       .
       .
    <Hnode2/>
  <root/>

  How it is possible to filter a node by one of its attribute value. For example:
  The id of a person - I guess that id = 20. In this case I would like to get the whole node (in this case node2_of_Hnode2) to get the personname = > 'Christian '.
  Just like a SELECT statement (WHERE ID = 20)
  
  Is it possible to get it in a single order or should it be buckled on all the lines in the Document. Can you please provide an example for me.
  
  Thank you for advice!

  The basic version is 10.

  Sorry, this is not a version.
  For example:

  SQL> select * from v$version;
  
  BANNER
  ----------------------------------------------------------------
  Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bi
  PL/SQL Release 10.2.0.5.0 - Production
  CORE     10.2.0.5.0     Production
  TNS for 64-bit Windows: Version 10.2.0.5.0 - Production
  NLSRTL Version 10.2.0.5.0 - Production
   
  

  The use of the extraction of the values?
  1. better in a Select statement. assignment directli in a variable, or by using the xmlquery function?

  PL/SQL or SQL calls to the XMLType methods such as getStringVal() or extract() function should be equivalent (save the change of context).
  However, none of them are the right way to retrieve a scalar value of a given node.
  You must use the rather extractValue() function (SQL only) for immediate release< 11.2="" and="" xmlcast/xmlquery="" starting="" with="">

  Another Question:

  I've seen a lot of options for dealing with XML files.

  In my case only query data in XML files is relevant.

  I've seen to many API called XMLDOM, DMBS_XMLDOM, XMLTYPE...

  When to use these APIs. Can you give me feedback on this please?

  It is a broad topic.
  An appropriate response will depend on your condition.

  -You have to deal with large files and if so what size?
  -Performance/memory management is a concern for you?
  -You want to extract unique values or process the XML content in the form of relational data?

  If you have any specific test cases to show us, please post in the {forum: id = 34} forum and make sure to include all the necessary details (see the FAQ).

• Add the node to the xml file

  Hello

  I'm trying to scan a file xml in the following way:

• How to check if a node exists in the XML file?

  I was asked to program a method to import data from xml files in our Coldfusion 8 Web site, I am new to the use of XML.

  My method worked however I encountered the following error:

  Element NETWORKORDER. SECONDARYADDRESS. CONTACTNAME is undefined in MYDOC.

  Investigation on the node in the XML file was not present.

  Is there a method I can use to resolve this error by checking if a node exists in the xml file, which works with my current code below?

  Since you already have the XML parsed in a document, the easiest is to use xmlSearch(). Take a look at the doc, it is pretty easy to use. Something as simple as:

  To the most complex as:

  And in both cases:

• Difference between xml files

  I found that I have somehow created a duplicate iTunes folder that caused problems with my music.  I am now fixing that but noticed that I seem to have two xml file.  One called iTunes Library.xml and iTunes Music Library.xml called.

  Can someone tell me what the difference is and what they do?  Should I have them both?

  I also seem to have a file called Itunessetup.exe.  He said that it is a windows file, but I use a mac.  Should it be there?

  Now the Windows files must be present.

  The Music Library.xml iTunes library file is the old name for the .xml and if you look at it you will probably see that it is several years old.  In fact, you need not or .xml. iTunes has never used, he created them only for other applications to use and if you do not have those in need, then you don't really have. Elsewhere the news versions of iTunes are not even them unless you turn it on in preferences.

• Write in an external xml file

  OK, so ive been reading on xml and found theres this big thing appeal. appendChild(). that let your add a node to an xml file.
  
  Here's the catch, I can write in an external xml file, without the need to load it, DIRECTLY through flex?
  
  or I have to use some php i.e. backend
  
  
  Thanks heaps!
  
  ojk007

  The Flash Player, when it is hosted by a browser, severely limits access to the resources of the host computer. In other words, you cannot read and write files. If the XML file resides on the server, then you can use the code server-side (e.g. PHP) and edit the file, or you can load the XML file into your Flex application on the client computer, change it, then refer to something that can write the file.

• Loading multiple Xml files.

• Problem with loading multiple external xml files

  I have a table named 'source', which consists of names of files external xml, the content of which I'm loading in another table called 'content '. I tried with the following text:

  for (i = 0; i < source.length; i ++) {}
  XML_URL = "' http://localhost/temp/ ' + source ;"
  myXMLURL = new URLRequest (XML_URL);

  }
  
  function xmlLoaded(evt:Event):void {}
  Content.push (myLoader.Data);
  }
  ---------------------------------------------------------------------------------------
  
  The problem is that in this way, I get that content of the last xml file and other items ' content ' are 'undefined '. Anyone know the solution to this problem or maybe another way to do this?
  
  Thanks in advance

  I tested the following with two xml files in the same folder (I would try the same thing) and put their names in the table source. Create two dummy xml for the test files.
  Here is my exact code (I've changed, I have one because it's italicized here in the forums):

  var content: Array = new Array();
  var source: Array = new Array ("media1.xml", "media2.xml");
  for (var a source) {}
  var XML_URL = ' "+ source [a];
  var myXMLURL = new URLRequest (XML_URL);

• XML file - child nodes table

  Just starting to learn more about XML.

  I have a simple XML I created which is

  
  
  
  Ambient
  
  
  panel1
  
  
  panel2
  
  
  panel3
  
  
  

  Using the XML property - child results node table of nodes in a table of 9 elements:

  #text
  Probe
  #text
  Probe
  #text
  Probe
  #text
  Probe
  #text
  

  My question is what are all the #text that are there?  Should the child nodes be not just the probes?

  It seems to me you may be heading down a dark path.  Instead of using the "table of nodes child" and fighting through the unnecessary complications and text nodes, let me suggest you look at XPath and using "get all matched Nodes.vi ' or 'Get first match Node.vi' to get the items.  XPath allows parsing XML child's play.

  For example:

  

  Of course, I hope that you use XP does not mean you use LV8.6 or earlier since the XPath screws are new to LV9.

  If you use LV8.6 or earlier, I suggest looking in the .NET functions to implement XPath.  Once you get the hang of it, it still beats the attempt to parse XML the old-fashioned way.

  As for the editor, I generate very few XML files by hand, for the most part I bring other programs and analyse them in LV again, XPath adjusts the rough edges.

• Two apparently identical xml files. A fine exception analysis expects a name

  Hey. For a beginner to xml, these look similar v:

  Analysis:

  Will not scan:

  Code is below. Thoughts why?

      private static NodeList GetNodeListFromInputStream(InputStream is) {
  
          NodeList list = null;
  
          try {
  
              DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory. newInstance();
              DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder(); 
  
              docBuilder.isValidating();
              Document doc = docBuilder.parse(is);  // FAILS HERE- why         // Get stream from xml file
  
              // 2 ways to do it- heirarchically from root node or getElByTag* as a list. We do list
              list = doc.getElementsByTagName("*"); 
  
          }
          catch ( Exception e )
          {
                  System.out.println( "\n\n*****************\n" + e.toString() );
          }
  
          return list;
  
      }
  

  If you don't find anything, why not try and write it yourself? You can easily write a parser of the state machine-based in order to transform the entrance in a simple way.
