How to get zclass attribute's value inside "Execute_default" method

Hi all,
I am displaying a link in UD step under "Objects & Attachmnents".I am using zclass. I created a attribute in zclass and i am creating a instance (background task) before this UD step and i will be setting a attribute of the zclass inside this create instance method.
My problem is, if i click the link, this method "BI_OBJECT~EXECUTE_DEFAULT_METHOD" is getting executed but i am not able to get the attribute value inside this method, eventhough i am setting the attribute value before the UD step.
Pls let me know, how to get the attribute's value inside "Execute_default" method, as i need to process further using this attribute.
P.S: I tried with both static & instance attribute. I can achieve the same using ZBO but my client needs to use only class.

Lei,
If you are concerned only about a couple of attributes, then you can manage with a separate copy of the data. But if the data is in bulk, better leave it to pl/sql side of validation.

How to get the name and value of an attribute on a node/element that is not a child

Hello,
Can someone shed some wisdom on how I can compare 2 xml nodes for differences.
My main challenge is I need to use the attributes/values of 'ProductDescription' and 'Features' as 'key' to identify the same node in
another doc with the same layout, but different content.
I am having trouble getting the name of the attribute on the node, 'ProductDescription' and 'Features'. I can only seem to get the node names, but not the attributes on the node. I need the name, because it can be different from doc to doc, so
I can't hardcode this.
Can someone please help with how to retrieve an attribute name/value on a node that is not a child. Here's an example of what
my xml looks like:
DECLARE
@myDoc1 xml
,@mydoc2 xml
DECLARE
@ProdID int
SET @myDoc1 ='<ProductDescription ProductID="1" ProductName="Road Bike">
<Features featureID = "1" featureName = "body">
<Warranty>1 year parts and labor</Warranty>
<Maintenance>3 year parts and labor extended maintenance is available</Maintenance>
</Features>
<features featureID = "2" featureName = "seat">
<Warranty>1 year parts and labor</Warranty>
<Maintenance>2 year parts and labor extended maintenance is available</Maintenance>
</Features>
</ProductDescription>
SET @myDoc2 ='<ProductDescription ProductID="1" ProductName="Road Bike">
<Features featureID = "1" featureName = "body">
<Warranty>2 year parts and labor</Warranty>
<Maintenance>3 year parts and labor extended maintenance is available</Maintenance>
</Features>
<features featureID = "2" featureName = "wheel">
<Warranty>1 year parts and labor</Warranty>
<Maintenance>2 year parts and labor extended maintenance is available</Maintenance>
</Features>
</ProductDescription>
I need to compare the attributes of 'ProductDescription' and 'Features' from @mydoc1 against @mydoc2 to see if they are the same based on those 2 nodes first. If they are, then i want to show the difference in the child elements.
This will eventually be an outer join to give me the differences betw the 2 docs based on those key values (node attributes).
I used node('//*') for the path, and value('local-name(../.)', 'varchar(50)') as element
,value('.[not(@xsi:nil = "true")]','VARCHAR(255)') AS new_value
...etc...
but that only gives me the node names, and the child elements. It does not give me back the attribute names and values from the node itself.
Thanks in advance for your help.
cee

Are you looking for something like this:
DECLARE @myDoc1 xml
SET @myDoc1 ='<ProductDescription ProductID="1" ProductName="Road Bike">
<Features featureID = "1" featureName = "body">
<Warranty>1 year parts and labor</Warranty>
<Maintenance>3 year parts and labor extended maintenance is available</Maintenance>
</Features>
<Features featureID = "2" featureName = "seat">
<Warranty>1 year parts and labor</Warranty>
<Maintenance>2 year parts and labor extended maintenance is available</Maintenance>
</Features>
</ProductDescription>'
SELECT T.c.value('local-name(.)', 'nvarchar(50)') AS name,
T.c.value('.', 'nvarchar(50)') AS value
FROM @myDoc1.nodes('ProductDescription/@*') AS T(c)

How to get the attribute value of an XML file??

How to get the attribute value of an XML file??
For example, how to get name and age attributes?
<student name="Joe" age="20" />

What are you using to read the XML file??
On the assumption of JDOM - www.jdom.org. Something along the lines of:SAXBuilder builder = new SAXBuilder(true);
Document doc = builder.build(filename);
Element root = doc.getRootElement();
List children = root.getChildren();
Element thisElement = (Element)children.get(n);
String name = thisElement.getAttributeValue("name")
try
int age = Integer.parseInt(thisElement.getAttributeValue("age"));
catch (Exception ex)
throw new InvalidElementException("Expected an int.....");

Here is attribute identifier operator from FB Help:
@ attribute identifier Operator
Usage myXML.@attributeName
Identifies attributes of an XML or XMLList object. For
example, myXML.@id identifies attributes named id for the myXML XML
object. You can also use the following syntax to access attributes:
myXML.attribute("id"), myXML["@id"], and myXML.@["id"]. The syntax
myXML.@id is recommended. To return an XMLList object of all
attribute names, use @*. To return an attribute with a name that
matches an ActionScript reserved word, use the attribute() method
instead of the @ operator.
Operands attributeName:* — The name of the attribute.
Example
How to use examples
The first example shows how to use the @ (at sign) operator
to identify an attribute of an element:
var myXML:XML =
<item id = "42">
<catalogName>Presta tube</catalogName>
<price>3.99</price>
</item>;
trace(myXML.@id); // 42The next example returns all attribute
names:
var xml:XML =<example id='123' color='blue'/>
var xml2:XMLList = xml.@*;
trace(xml2 is XMLList); // true
trace(xml2.length()); // 2
for (var i:int = 0; i < xml2.length(); i++)
trace(typeof(xml2
)); // xml
trace(xml2.nodeKind()); // attribute
trace(xml2
.name()); // id and color
} The next example returns an attribute with a name that
matches a reserved word in ActionScript. You cannot use the syntax
xml.@class (since class is a reserved word in ActionScript). You
need to use the syntax xml.attribute("class"):
var xml:XML = <example class='123'/>
trace(xml.attribute("class"));

I suggest you can get the document sets properties like the PowerShell Command below:
[system.reflection.assembly]::loadwithpartialname("microsoft.sharepoint")
$siteurl="http://sp2013sps/sites/test"
$listname="Documents"
$mysite=new-object microsoft.sharepoint.spsite($siteurl)
$myweb=$mysite.openweb()
$list=$myweb.lists[$listname]
foreach($item in $list.items)
if($item.contenttype.name -eq "Document Set")
if($item.folder.itemcount -eq 0)
write-host $item.title
Then you can use Export-Csv PowerShell Command to export to a CSV file.
