Need to replace/modify an element attribute

Hi,
I need to read an XML file and modify the value of an XML element attribute and write the modified element back to the file. This element is two levels deep in the heirarchy,
currently i am reading all the children and modifying the value of this particular attribue and writing all the children back.
Does anybody know of a method where we can do a replace operation on the Document rather than the lengthy process that i am currrently using??
Thanks

you might want to look at STX streaming transforms-

That seems a good match for a simple replace problem.

Replacing harcoded XML element attributes with variables

Is there any way for Xpath expressions in JAVA to refer to variables (for an attribute) instead of harcoded strings (like 'abc' and 'xyz' below)
So below ... 'abc' , 'xyz' could be varaibles.....
String getServerInstance="/Accounts/Account[@code='abc']/TestingProgram[@code='abc']/Modes/Mode[@code='xyz']/*";
Thanks a lot

I have a class now that resolves variables:
public class Resolve_Xpath_Vars implements XPathVariableResolver
     public Object resolveVariable(QName var)
try {
          if (var.equals(new QName("pqr")))
                    return new String("pqr");
          else if (var.equals(new QName("abcde")))
                    return new String("abcde");
else
return null;
catch (Exception ex)
          ex.printStackTrace();
          throw new RuntimeException();
NOWWWWW
how do i configure my XPATH expression to call this class to reolve my varaible....
XPATH EXPRESSION IS:
"this.Account" is the variable that the class should resolve.....to "pqr"
String getAccnt="/Accounts/Account[@code="+"'"+*this.Account*+"'"+"]/*";
Once resolved to "pqr" then i can make the following call:
NodeList nodeList =(NodeList) xPath.evaluate(getAccnt, inputSource, XPathConstants.NODESET );
any help is appreciated.............

What do you mean by "Elements"?
Elements in a flat image or Layers?
Could you please post a screenshot with the Layers Panel visible?

Need to exclude the empty elements after mapping in xslt.

Hi Team,
I have a requirement. I need to invoke a wsdl which will have some po details. I'm using transformation to map the value from my local bpel variable to invoke variable. It is mostly a one-one mapping. no functions no looping and no complex transformation. Now the requirement is that I need to only send the elements which has the value also to add, there is no particular element which can be empty. There can be three elements empty or four or any. I need to map all and then I need to send only the elements those has values. Below is my mapping.

Modify Active Directory attributes

I have a strange query here -
I am working with a small base of active directory users. Their account properties in active directory has all the information like phone, email, webpage etc. Only recently all of the users migrated to Gmail which means that their username remains same for
ex. firstname.lastname but their email part changed to Gmail.com.
So earlier it was [email protected] & now it
[email protected]
Is there a way I can change just the domain part of their email through Powershell? In otherwords, can I change AD attribute, in this case email without going through them manually.
Thanks in advance.

Assuming you need to modify the mail attribute, this PowerShell V1 script should work. However, I have not tested this:
$Searcher
= New-Object System.DirectoryServices.DirectorySearcher
$Searcher.SearchRoot
= "LDAP://dc=MyDomain,dc=com"
$Searcher.PageSize
= 200
$Searcher.SearchScope
= "subtree"
# Retrieve all objects with an email address using @xyz.com.
$Searcher.Filter =
"(mail=*xyz.com)"
$Searcher.PropertiesToLoad.Add("distinguishedName") >
$Null
$Searcher.PropertiesToLoad.Add("mail") >
$Null
$Results =
$Searcher.FindAll()
ForEach ($Result
In $Results)
    $DN
= $Result.Properties.Item("distinguishedName")[0]
    $Email
= $Result.Properties.Item("mail")[0]
    # Modify email address.
    $Email
= $Email.Replace("@xyz.com",
"gmail.com")
    # Bind to the user object.
    $User
= [ADSI]"LDAP://$DN"
    # Assign new value.
    $User.mail
= $Email.ToString()
    $User.SetInfo()

Richard,
I need a script which is almost identical to this in Powershell V2 format... are you able to help?

Column value substitution in tabular form element attributes

We started to discuss this at Re: Tabular form with Ajax
I also mentioned this at Re: how to make only some rows editable in html db.
but thought that this deserves its own thread.
In Doug's sample Sudoku application in that thread, he uses #COLUMN# substitution in the Form Element Attributes and it works fine, but in my example page at http://htmldb.oracle.com/pls/otn/f?p=24317:219 I used the same technique and no matter what I do, the #COLUMN# substitution is not expanded by the Apex engine.
This is driving me nuts, any ideas why it works in one application but not in another?
Thanks

Hm, you might be right.
I copied your row template and modified it at http://htmldb.oracle.com/pls/otn/f?p=24317:219
The styling looks terrible, not sure why, the template is simply
<tr>
<td class="t10data">#EMPNO_DISPLAY#</td>
<td class="t10data">#ENAME#</td>
<td class="t10data">#JOB#</td>
<td class="t10data">#MGR#</td>
<td class="t10data">#HIREDATE#</td>
<td class="t10data">#SAL#</td>
<td class="t10data">#COMM#</td>
<td class="t10data">#DEPTNO#</td>
</tr>I had a lot of trouble getting this to work because the wizard generated tabular form appends 2 hidden fields containing the PK and the row-checksum to the last (editable?) field on each row. If the last editable field has #COL# substitution, it expands the substitution and forgets to close the INPUT tag thus causing malformed HTML (I think this is a bug in the rendering engine).
The readonly condition is sal>1000 which now works. The SAL>1000 fields are now readonly.
But now the update process is broken. If I enter a number in the first blank SAL field (empno=3641) and click Submit, I get no errors but the change is not saved. Wonder why.
Hopefully, Scott (Spadafore) will take mercy on our amateurish experiments and give us some definitive answers soon!
Thanks.

Need help in Insertion of Element in DefaultStyledDocument

Hello:
I am developing an XML editor by extending the DefaultStyledDocument of javax.swing.text package. I am not able to insert an element in the document.
This is what I have done: (I need to insert one BranchElement, with two leaf child elements.)
I inserted the text in the document corresponding to the first child element using insertString() method. In the insertUpdate() method of the document, I am creating the branch element and its first child covering the inserted text. I then call the insertUpdate() method of DefaultStyledDocument. Similarly, I insert text corresponding to the second child and modify the element structure inside insertUpdate() and then call the insertUpdate() of DefaultStyledDocument().
At the end of the execution, the element structure is okay, but all the inserted text also becomes a part of the previous element.
for example,
if I have the following element structure at the beginning: (element offsets are in the square brackets besides their names, child elements are indented.)
html [0 2]
start-leaf [0 1]
end-leaf [1 2]
and I insert body at position 1 with its two children (each of length 1)
I get the following element structure:
html [0 4]
start-leaf [0 3] //why this?
body [1 3]
start-leaf[1 3] //why this instead of [1 2]?
end-leaf [2 3]
end-leaf [3 4]
And, I am not able to see the Views corresponding to the inserted elements.
(I tried without modifying the element structure explicitely, but it doesn't work that way.Also, I am able to remove elements from the document. In that case also I am following a similar logic: remove the data from the document using remove() method and modify the element structure inside removeUpdate(). and it seems to work fine.)
Can anyone please help me understand why this is happening?
Thanks a lot!

Portege Z830 - screen has been broken and I need to replace it

Hi
I have Toshiba Portege z830. My screen has been broken and I need to replace it.
Is it possible to install some IPS screen instead of original LTN133AT25-601? Which IPS screen is compatible with LTN133AT25-601?

Hi
The original LCD which was used in Z830 was an 13.3"(HD) 1366 x 768 TFT Color LCD.
So if you want to use other display, then you should pay attention to the screen size and the connectors.
I think these are most important key elements.

Error 103: application.initialWindow.autoOrients is an unexpected element/attribute

Hello.
I'm using Flash Builder 4.5 to experiment with building a mobile app for my Android Nexus One. In order to keep the app in landscape mode, regardless of the orientation of the device, I've read that I need to set the following in the "AppName-app.xml" file:
<aspectRatio>landscape</aspectRatio>
<autoOrients>false</autoOrients>
And this does work fine in the debugger, however when I attempt to test it on my connected device it throws this error:
Error occurred while packaging the application:
D:\Projects\FlexMobile\AppName\bin-debug\AppName-app.xml(108): error 103: application.initialWindow.autoOrients is an unexpected element/attribute
I know that I'm able to build and test apps on my device, as I've been through the Flex Test Drive for Mobile tutorial (http://www.adobe.com/devnet/flex/testdrivemobile.html) and was able to build and run that app with no issues and this app I'm currently working on does run on the device if I do not attempt to restrict the auto orientation.
Thank you.
(Note: I'm re-posting this from the Flex SDK > Developers forum.)

User rblaa provided that answer in http://forums.adobe.com/thread/858772.
The <autoOrients> node (along with several others) occours twice in the generated -app.xml file. Do not un-comment the first instance, instead edit the parameters set in the second already un-commented autoOrients node.

Using element attributes to show changes

Hi,
I'm working in a structured environment in FM7.2, and the job requires that we save out to SGML. I've been asked to show changes to my documents using a visual element but not change bars (they're already being used) - confused? I hope I can explain it clearly.
We're creating parts lists, so basically we're working with pages of tables. We have the data from the OEM of the parts lists in hard copy. We have to reproduce that list for our client. The hard copy from the OEM shows their changes to the parts list on the left side of the table - we need to keep those marks but we also need to indicate changes to the list where our client has changed parts and we need to show those changes on the right side of the table with change bars. What I'm thinking is if I could use element attribute data to show the OEM (left side) changes and then that allows me to use the change bars for the client (right side) changes. The element for the item/part already has an attribute called 'change'. I recall reading somewhere that attributes can be used like this but I can't recall where I read it. If all that makes sense and it can be done, my question is how to implement it?
Any thoughts on this appreciated.

The latest documents I copuld find describing the workings of EDD etc. are those two:
FrameMaker 8.0 Structure Application Developer's Guide
FrameMaker 8.0 Structure Application Developer Reference
It seems they are not linked from any page, at least Google was not able to find them. The former version (FM7.1) of those documents as a single document can be found here:
http://www.adobe.com/devnet/framemaker/onlinemanuals.html (Structure Application Developer Guide)
Since the way the EDD works has not changed very much, you may take any of those, to learn about context rules etc.
Scriptorium Publishing has some workbooks available:

How to capture element/attribute

We have an export client that converts the Frame file to xml. We are using "LightTitle" element at various places, this element also has an attribute called "LightColor".
When I look at the output xml, I can see all LightTitle elements, but only some of them (2 out of 10) have the LightColor attribute!
How can we capture the attribute associated with a specific element and output it to the final xml?
Thanks.

If your LightColor attributes do not contain ant content - then they will not be written out - you can change the rules to add a 'dummy' if you need them in the XML - OR -(and probably easier) post process your XML and add the missing elements/attribute pairs based on rules in your XSLT or program...
have fun.

Read Workflow Container Elements attributes

Hi,
I am using a F.M <b>'RH_GET_TASK_ATTRIBUTES'</b> to get the attributes of the <b>Workflow container</b> elements.
But the above F.M does not show the element attributes that I create inside the Workflow Builer under <b>Workflow Container Block</b> and I dont select either Import or Export Properties.
Is there any F.M that reads ALL Workflow Container elements.

If you want to clear a single element, use a container operation and assign it to space. If you need to clear an internal table, create another internal table container element that is always empty. Then, inside the container operation assign the empty table to the table you want to clear.
Basically, you are doing this:
container_element = space. OR container_element = ' '.
container_internal_table[ ] = container_empty_internal_table[ ].

Flash CS5.5 to iOS error 103: application.version is an unexpected element/attribute

Hello,
I am trying to publish from a flash file, an .ipa file to use in ipad and iphone, but keep receiving the "error 103: application.version is an unexpected element/attribute" error message.
I already publish the app in flash CS5 and it was ok but today i install CS5.5 and the error does not alow me to publish the same file...
Is it an Air ADL problem?
Any suggestions?
Thanks

I don't know if it's an official bug.... Adn I don't know if they will really solve it...
I called 3 times to Adobe Phone Support. I've never been told that it was an official bug. Nobody seemed to know about that bug....
1st call: They told me to go to www.adobe.com/devnet/, saying that I will find the solution there... I found nothing.
2nd call: They told me to call Apple... They said I need a Flash CS5.5 certificate... Of course, Apple does not deliver "Flash CS5.5 certificates". I guess they just wanted to get rid of me...
3rd call: They gave me a phone number to call the Flash Developers Support Center. That phone number was not working....
Each time, I asked them if they can send me a Flash CS5 version, which was working well. They always said it was impossible.
I really need to be able to publish iPhone apps as fast as possible, otherwise I will lose a big contract...
I think my next call will be to my bank... to cancel the payment I made on my credit card to purchase that Flash CS5.5 software.

I need serial number for my elements 4.0 disc provided with my Leica camera?

i need serial number for my elements 4.0 disc provided with my Leica camera please?

It is almost impossible to transfer FCE as there are so many essential hidden files that workers in an Apple Store will know nothing about. The app needs to be installed from the original DVD.
Other than buying another copy your only chance (very remote) is to contact the Apple Store and see if they are able to get a replacement number from Apple.

Find and replace several array elements

I have a 2d array and want to subsitute any negitive value with a marker e.g "**" or any indicator which would be identified easily. I am using Labview 5.1

Hi,
The data type of you array is probably numerical. If you haven't already
done this, the first step would be to convert the data to a character
data type. This is easy done with 'Number to Decimal String'. Tie the
output to a 'For Loop' and the search and modify each element in the
array using a combination of 'Search 1D Array', 'Replace Array Subset',
and shift registers.
The first iteration of the 'For Loop' will give you the first index of
the first '-1' found. Use that index value to replace the the '-1' with
your '**'. Increment the index and pass it to the shift register to use
as a starting point for the next interation's search and replace process.
There may be a more "packaged" way of doing this but I just love For
Loops.
Hope this helps ...
