Could xml files be displayed in a more readable / structured way?

Within a software test environment, xml files have to be checked on their content. When using the "View Page Source" the xml file is displayed as it is.
It would be very helpful if Firefox would have an option to display xml files in a more structured way to make then more readable.
This will save a lot of time, because now the file should first be downloaded and opened in another application.

Hi Atul,
The standard DMS system does not offer this feature!!
However,there are a couple of options you may explore.
- In SE38,run report DMS_KPRO_READ to retrieve the original file names of a DIR.
- Alternatively,you may also implement SAP Note 1015165 to display file names of a DIR.
Hope this helps.

Parsing large xml file and display using swing

Hi all,
I want to read a large xml file and display graphically in swing as a tree structure.
I implemented it and works fine for files of 5MB size after increasing the jvm heap size (-Xmx). If the file size is larger than 5MB it throws out of memory error. I'm creating a custom datastructure from the xml and I'm using sax parsing.
After displaying the datastructure, the user could do some operation on this, like search etc.
Can any of you suggest a method, to support larger files ? What I'm looking for is create the datastructure in file system, rather than in memory.
Any other tips for memory management would be greatly appreciated
Thanks in Advance.

How to format and display xml file as displayed in IE

I want to display the xml file as it is displayed in Internet Explorer. Which component I should use and how?
Thanks in advance
Sachin

You mean you want to see the XML source?
You need to replace the characters '<' and '&' with corresponding entities '<' and '&'. You can use replaceAll, but do the ampersands first.
Then I suggest you probably want to put them in a <PRE> block.

Create a list from an XML file no display

I have a multiline Dynamic text box called projList.
I am trying to populate it from an xml file and create a
clickable list.
The trace works but cannot get to display the list in the
text box.
As far as the clickable goes, haven't gotten that far yet.
Help very much appreciated.
The xml is structured like this:
<?xml version="1.0" ?>
- <images>
- <pic>
<Image>/Butler/Images/sfah2_small.jpg</Image>
<Category>Institutional</Category>
<Proj_title>FRESH AIR HOME</Proj_title>
Please see code below:
import mx.xpath.XPathAPI;
var allproj_xml:XML = new XML();
allproj_xml.ignoreWhite = true;
allproj_xml.onLoad = function(success:Boolean) {
trace("onload...");
if (success) {
trace("success...");
var thePath_str:String = "/images/pic/Proj_title";
var title_array:Array =
XPathAPI.selectNodeList(this.firstChild,
thePath_str);
for (var i:Number = 0; i < title_array.length; i++) {
trace(title_array
.firstChild.nodeValue);
projList.addItem(title_array.attributes.Proj_title);
} else {
trace("error loading XML");
allproj_xml.load("allimages.xml");
stop();

This did it:
projList.addItem(title_array
.firstChild.nodeValue);

XML DB: As XML file size doubles validate time more than doubles

Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
We have default XMLDB install. I am using schemavalidate() to successfullly validate xml files against a registered xsd. For some reason as the files size doubles the time to validate the file grows at a faster rate than double? We wanted to generate approx 18MB files since they hold 5000 records. But as you can see it appears I would be better off generating six 3MB files instead. What init.ora or xdbconfig.xml parameter might I change to help out with behavior? Any other ideas of why this happening? Is this an example of "doesn't scale"?
1.5MB 3 Seconds
3MB 15 Seconds
6MB 1 Minute
12MB 6 Minutes
18MB 16 Minutes
Code is simple..
procedure validate_xml_file (p_dir in varchar2, p_file in varchar2) is
v_xmldoc xmltype;
begin
select XMLTYPE(bfilename(p_dir, p_file),NLS_CHARSET_ID('AL32UTF8'))
into v_xmldoc
from dual;
v_xmldoc.schemaValidate();
end validate_xml_file;

If I take the clause off the end of the cview table this procedure does not work at all.. It fails at the schemavalidate call...
Error report:
ORA-19030: Method invalid for non-schema based XML Documents.
ORA-06512: at "SYS.XMLTYPE", line 345
ORA-06512: at line 26
19030. 00000 - "Method invalid for non-schema based XML Documents."
*Cause: The method can be invoked on only schema based xmltype objects.
*Action: Don't invoke the method for non schema based xmltype objects.

here's an example:
http://jdj.sys-con.com/read/37550.htm
you need to have a class Tractor with all those properties and then use readObject.Somehow you need to tell the Encoder/Decoder what Tractor means..
hope this helps!!

How do you display xml file with xlst sheet in jsp

I have an xml file with accompanying xslt file (and several images that are used in a single directory. If I doubleclick on the xml file, it displays perfectly in my browser - Formatting, images and all!
          The 100 dollar question - How do I duplicate this behavior in a JSP page in WebLogic 8.1 using the code in the xml and the accompanying xslt (formatting) file? I tried simple embedding the xml code in the jsp, but that didn't seem to work. What is the secret?
          Okay, I need to add a bit more information here. I understand that it is really easy to just redirect to the XML file. The issue is really security. I want the XML to be inside a jsp that will only allow validated users to view it.
          Another way to look at the problem would be, can I add a jsp security tag to the xml file? Or how to I add the xml code inside a jsp and keep the path references to the xslt and graphics.
          Hope the added information helps
          Thanks,
          Ken

How to display an xml file contents in jsp as tree view

hi,
Iam trying to read an xml file and display the structure in jsp as tree view, can any one help me

Use a [XML or DOM parser|http://java-source.net/open-source/xml-parsers] to read a XML file into a tree structure of Java objects.
Use the [Collections API|http://java.sun.com/docs/books/tutorial/collections/index.html] to get hold of the relevant elements in a tree structure.
Use JSTL´s [c:forEach|http://java.sun.com/javaee/5/docs/tutorial/doc/bnakh.html] tag to iterate over a Collection in JSP.
Use HTML´s [<ul>/<li>|http://www.w3.org/TR/REC-html40/struct/lists.html#h-10.2] or [<dl>/<dt>/<dd>|http://www.w3.org/TR/REC-html40/struct/lists.html#h-10.3] tags to represent a tree in HTML.

Why MAX5.0 not report right XML file settings from AVT GigE camera?

I have a AVT Prosilica GC660M GigE camera. It had a touble to synchonize with an external trigger. My ex-colleague posted this long time ago (http://forums.ni.com/t5/Machine-Vision/Problem-with-external-trigger-on-GigE-camera/m-p/1060572/high...), so I think it might be better to start a new one. Inside the MAX, there's only one option under the "ExposureMode" as "timed" which only use preconfigured time, and cannot be trigger by an external signal. The workaround is to manually register it inside the camera. It was thought to be a bug and an update of firmware should fix it.However the problem remains after I recently upgraded the firmware. And o I installed the AVT package. Both the MAX and the AVT GigEViewer correctly retrived the camera firmware version as 1.42.02. Yet MAX still shows only the "timed" option, while the GigEViewer shows all four enums as described in their attribute manual "Manual, Auto, AutoOnce, External". I had tried to delet the xml and files associate with the camera under IN-IMAQdx\Data. However everytime MAX genenrates them excatly the same with only "timed" option in the XML file. Now it feels more like something is wrong with the MAX instead. I wonder how to fix it.
Thanks,
Lei

Hi Lei,
I am not exactly sure why you are not seeing all the attributes, but it could be a few different things causing it. First let’s just make sure you have all you attributes being displayed (follow instructions from link below). What happens if you delete the XML file then set your camera to “External” in the GigEViewer software, then load MAX? Do you see any changes? Can you post a screenshot showing the camera attributes from MAX. If you have your camera set to External from GigEViewer and you try to grab from the camera in MAX do you get a timeout error, does it trigger external, what happens?

How to extract data from an arbitrary xml file and export in a nice csv file?

Hallo,
I'm facing big problems in the use of XML files. I have an
application which generates XML files with clusters containing arrays
and scalars like in the example pasted below. My task is to
read it and export the data in a human-friendly CSV document.
Since I don't know the actual content of the cluster, I need some kind
of intelligent vi which goes through the XML file looking for arrays
and other data structures in order to export them properly in the CSV
format (columns with headers).
Thank you

Thank you again,
I'm forwarding my vi draft with many comments and an xml file sample.
Data in cluster is stored according to the LabVIEW schema, infact it is generated by LabVIEW.
What I'm trying to do is to access the element of the cluster and read their content using the Invoke node and Property node functions. Could you give it a look, there may be something wrong, I'm not able to access cluster children.
Which funcions should I use? Could you give me an example? You may use the draft I enclosed...
Then write these data in a csv file
should be the easier part.

Using an XML file for server URL instead of hard coding

I can't find a good example.
Could someone give me an example of using a local XML file to set a server url variable so i don't have to hard code url's?
This works and i can trace the xml file but how do i access the individual xml data nodes?
protected function initApp():void
     var loader:URLLoader = new URLLoader(new URLRequest("config.xml"));
     loader.addEventListener(Event.COMPLETE,configLoadComplete);
private function configLoadComplete(event:Event):void
     trace(event.target.data);

Hi,
<a href="foobar.xml">right click and select save as from the context menu</a>
or
write your xml data or a copy of it with a different extension (text) so that it is not parsed as application/xml-xhtml
or
Use AJAX to retrieve the xml file and display it as the textContent of a <textarea>
window.open wraps the xml markup in html tags for display purposes.

Could xml files be displayed in a more readable / structured way?
