XML question on textnode null value

Hi,
I don't known XML use, I'm learning.
My question is
If in the DomDocument newsXML I append to "node" the newelement and a textnode, initially with not null value. Why, then, can't I setNodeValue to Null?
newelement:=xmldom.createelement(newsXML,element_name);
newnode:=xmldom.appendchild(node,xmldom.MAKENODE(newelement));
Textitem:=xmldom.createTextNode(newsXML,value);
newnode:=xmldom.appendchild(newnode,xmldom.MAKENODE(Textitem));
xmldom.setNodeValue(newnode,null); not possible!!!
Why?
Yet,
is There another way to append a leaf null in the tree of xml?
Thanks!

I maybe wrong about this because my XML is a little rusty, but I thing a Node is null when we create it. It is only by adding a TextNode to it that we make it not null.
If that's the wrong answer I will just suggest you visit one of the OTN XML forums which you can find here.
Cheers, APC

How to find out the null values in table

hi experts,
my version is oracledb10g:
i h'd simple doubts.
for eg:
create table ex1( e varchar2(20));
insert into ex1 (null).
insert into ex1(e)
count will be: 2
i can easily found out the value 'e'.
so my question is:
how can i found out the null values in the table and i want to delete the null values from the table.

delete from <table_name>
where <column_name> is null;Ideally you'd just place a NOT NULL constraint on the column in question, thereby prohibiting NULL values from entering into the system (assuming your business requirement is that the column MUST always have a value).

About xml and null values in 10g

Hi, I have an UCM GetFile webservice component wich receives 4 arguments, two of them are null values (rendition and extraPops), and the xml request generated by obpm is:
<GetFileByName xmlns="http://www.stellent.com/GetFile/">
<dDocName>V_123410</dDocName>
<revisionSelectionMethod>latestReleased</revisionSelectionMethod>
<rendition/>
<extraProps/>
</GetFileByName>The problem is: On UCM web service, an empty tag like <rendition/> is treated like a "empty string" value, instead of a null value, and then the response i get isn't the expected.
What I want do to is change this behavior, and when I put null values in requests, the obpm should not write those tags. Is that possible?
Should be like that:
<GetFileByName xmlns="http://www.stellent.com/GetFile/">
<dDocName>V_123410</dDocName>
<revisionSelectionMethod>latestReleased</revisionSelectionMethod>
</GetFileByName>Thanks!

Hi,
I have question regarding aggregates. It's possible to read data from BW aggregates? We have webi reports on a SAP BW multi cube and we would like to optimize retriving query.
>> Because you are using the BW Query as the source all the items that you have done so far in terms of aggregation, indexing, ... is all valid and there are no specific steps required to leverage it with Web Intelligence. Make sure the aggregates are "correct" meansing that they do reflect what you are asking for in the Web Intelligence query panel
How can we filter in webi query null (#) values. If we create condition that some variabe is diffrent from # we still get null (#) values in report.
>> You should be able to create a variable. in case you tried that already could you be more specific ?

Getting null value while parsing "XML String" with encoding WINDOWS-1252.

Hi,
when I am converting the Follwoing "xml string " to Document, I am getting the "null" as a document value.
    String strXML = "<?xml version="1.0" encoding="WINDOWS-1252"?>
                          <category name="SearchByAttributes" value="Search By Attributes">

                               <attribute name="Sequence" value="0001"/>
                             </item>
                            </category>"
My "xml string" has the encoding vaule: WINDOWS-1252.
I am using the following code to convert the "xml string" to Document. I am getting the Document values as a "null" while converting the above "string xml"
        String strXML = //my above string xml.
        DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
        docBuilderFactory.setIgnoringElementContentWhitespace(true);
        docBuilder = docBuilderFactory.newDocumentBuilder();
        doc = docBuilder.parse(new InputSource(new StringReader(strXML)));
        System.out.println("doc value.."+doc)//I am getting null value for "doc".
Can anyone help me to resolve the issue.

//getting Element Attribute list as an...."null"(I am expecting output value object reference but it is printing "null"
(without the rest of the code, i'm guessing that) most likely you are grabbing the first child node of the item element. however, you are not accounting for some text nodes that are most likely in that list, like the whitespace between the item element and the attribute element. please go read some tutorials on xml, there are thousands of them out there, and they will answer all you initial questions much more efficiently than posting each step to the forums.

Need help Take out the null values from the ResultSet and Create a XML file

hi,
I wrote something which connects to Database and gets the ResultSet. From that ResultSet I am creating
a XML file. IN my program these are the main two classes Frame1 and ResultSetToXML. ResultSetToXML which
takes ResultSet & Boolean value in its constructor. I am passing the ResultSet and Boolean value
from Frame1 class. I am passing the boolean value to get the null values from the ResultSet and then add those
null values to XML File. When i run the program it works alright and adds the null and not null values to
the file. But when i pass the boolean value to take out the null values it would not take it out and adds
the null and not null values.
Please look at the code i am posing. I am showing step by step where its not adding the null values.
Any help is always appreciated.

Null value for int and datetime date type in xml schema

hi:
I am embarrassed by a qustion in xml schema; i defined a xml schema file like
this:

<xs:complexType>

<xs:element name="s_time" type="xs:dateTime"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
and I send this file to workflow clientrequest() node, I wanted to receive data
in this schema file.but when i send null value to the element "user" and "s_time"
in workshop test tool(test soap),and use function in xmlbean like isNilUser or
isNilStime, one error occur.
I don't kown why, I had to ask the engineer of bea in china, one told me a bug.
is that true?

Visakh16 I cant agree more with you on it, it is good but in production u cant have them change maxrows. I think
Patrick Hurst is a better option. debug the package have it running and move up
Please mark as helpful and propose as answer if you find this as correct!!! Thanks,Dia Agha .
Hmm..Why do you need to change it in production?
What I suggested was to tweak the setting in dev machine so that it interprets the Excel file datatypes correctly when doing development. Once mapping is set correctly then it will work fine when in production or in any other environment. The tweaking is
just to make sure it interprets the datatype correctly at design time and has nothing to do with production deployment

How to avoid the null values from xml publisher.

I am creating a report which have the claim numbers with the values CLA001,CLA111,null, null . when i preview my report it is showing some spaces for null values also. How can i avoid the spaces from the report.
I am giving for loop for the claim numbers in the template.
<?for-each:ROW?> <?sort:CLAIMNUMBER;'ascending';data-type='text'?>
<?CLAIMNUMBER?>
<?end for-each?>
Please help me out to solve this problem.
Thanks,

Hi Sheshu,
According to your description, you are experiencing the null values and infinity values when browser the calculated measure, right?
Based on my research, the issue is caused by that dividing a non-zero or non-null value by zero or null. In this cases, we need to check for division by zero to avoid this situation. Here is the sample query for you reference.
IIF(
Measures.[Measure B]=0,null,
Measures.[Measure A] / Measures.[Measure B]
If you have any questions, please feel free to ask.

Missing XML elements are no longer treated as NULL value (MDM 7.1 SP04)

Hello,
We have a problem with importing XML files with missing XML segments (and hence missing XML fields) in XML file.
In MDM 7.1 SP03 (7.1.03.72), missing fields within a missing segment (so no tags at all for segment and fields) were still represented in the import manager as NULL value in the value mapping, making it possible to do value mapping and to import this NULL value into MDM (overwriting existing values in MDM).
As of MDM 7.1 SP04 (we are running 7.1.04.126) the missing fields within an missing segment are no longer represented in the import manager as NULL value in value mapping!
I don't know if that's a new 'feature' in SP04 but we are now running into following problem:
- We are importing customer data from ECC into MDM, where some segments are optional
- The fields within the (optional) segment are mapped to a multi-valued tuple field
- When we now import a customer that has values for the optional segment, the tuple field gets filled correctly
- When the optional data is now removed completely from the customer in ECC, we don't get that segment anymore in the XML file (this is how the Idoc works on ECC side, if all entries from the optionel segment are deleted then the complete segment is missing in the XML file)
- In SP03 we replaced the existing tuple records with the NULL value (leaving 1 empty tuple record, but this is known issue to SAP, so we've accepted this for the moment)
- In SP04 we cannot replace the existing tuple records anymore, since when complete segment is missing, the fields within that segment gets no value at all (in source values). So we are not able to replace the existing tuple records with NULL/nothing, leaving the 'old' tuple values in MDM!
Does anyone have solution for this (that also works with SP04)?
We already tried to replace the complete record in MDM (instead of updating it, this is possible since we always get the latest (and complete) status of a customer), but we are also mapping the remote key, and hence you are not allowed to replace the record during import!
Other solution could be to have PI add any missing segment into the XML message, but we first want to make sure that this cannot be handled within MDM Import Manager itself.
Thanks in advance,
Marcel Herber

Hi Marcel,
I haven't tried it with XML file but i hope it may help you.
long back i need to send one field with value null if it doesn't come in source file and if it comes then original value.
What i did, i loaded a file which does not have this field, so in MDM Import Manager, under source hierarchy i created a field say ABC and map this field with target field and its value Null with Null, i also save this property in map using configuration options-->Automap fields when loading map = Yes
So whenever a file come with missing field ABC, automatically this field get created and mapped with target field and its value Null with target Null. on the other hand, If this field actually comes in Source File(Delimited, Excel) ABC then this field with its original value gets map with target field value. That time it worked fine.
Just try and revert with result if it helps..
Else, using PI is the best option to create that missing segment into the XML message.

Null values in Numeric fields of Datasets

I am wondering if anyone has run into this problem before and
checking to see if anyone has an elegant solution.
I have a rather large data set. (actually 5 of them on a
single page) I am sorting certain columns in a table as numbers so
i assign the variable " ds1.setColumnType("somenumbercolumn",
"number")" In most cases Spry works great and it sorts by numbers
properly. The problem is some of the fields in the XML file are
null and I am trying to sort them as a number. Spry actually
adjusts for this (as far as i can tell) and treats them like a 0
which isn't exactly ideal considering there are real zero values in
the data. I know spry doesn't currently format numbers:
So here is my question. Does anyone one have a solution to
fixing null values in a table so that it is still sortable but
doesn't display a "0" and instead displays something like "--" or
whatever. I have the option of editing the XML file as well, but I
still need the table to sort by number.
If not null values, how about non numeric fields which can
still be sorted in a numeric column?

Hi,
We have an old post that raised a similar problem with yours.
The post can be found
here
For you situation, you should add an if condition for the
rows that have 0 and to add a custom string instead 0.
for (var i = 0; i < numRows; i++)
if(rows
[ "field_name"] == 0)
rows[ "field_name" ] = '--';
Hope this helps you,
Diana

GetParameter() null value

Hi all,
We are having a problem using the request.getParameter(String) method. We are using the method to define an argument for a Java Webstart (jnlp mime type) file we are creating with jsp. Other arguments have been successfully created using the request.getServerName() and request.getRequestURI() methods. The getParameter() return value looks fine if printed back to HTML. The jsp file creating the jnlp file is called using an HREF created inside another jsp file as follows:
<a href="xmlfetch.jsp?filename=mti.xml""></a>
The param value for filename in each HREF is filled using an String array entry (i.e. +names).
The xmlfetch.jsp file uses StringBuffers to capture/store the servername, uri and param data as follows:
StringBuffer svrname = new StringBuffer();
svrname.append(request.getServerName());
StringBuffer requri = new StringBuffer();
requri.append(request.getRequestURI());
StringBuffer fname = new StringBuffer();
fname.append(request.getParameter("filename"));
All 3 variables look ok if dumped in html as follows:
out.println("svrname=" +svrname);
out.println("requri=" +requri);
out.println("fname=" +fname);
But only the param value is null when the variables are passed as arguments in the jnlp stream as follows:
<argument><%=svrname.toString()%></argument>
<argument><%=requri.toString()%></argument>
<argument><%=fname.toString()%></argument>
So the question is ... why do the parameter values evaluate to non null when dumped to html but become null when used as an argument for jnlp? AND what is the difference between the strings returned by the 3 request methods we are using as arguments (i.e. why do 2/3 work?).
ANY HELP APPRECIATED:)

I have tried the parameter specification both with and without quotes but either case results in null value for argument going into the Java Webstart (.jnlp) file that I create in the second jsp file (xmlfetch.jsp). What I don't understand is why the parameter looks correct when sent out.println() but is null when not printed and only used for the jnlp app argument. Both the other variables assigned using request.getXXX() methods are ok as arguments...only the parameters passed from the first jsp page (mtiquery.jsp) to the second jsp page (xmlfetch.jsp) become null when used as the jnlp argument.
Anyone ... please help. :)
Here is the code for the first jsp page. This page creates a table of filenames each of which has a href link to the second jsp page and passes it's filename as the parameter.
<%@ page
language="java"
import="java.util.*,java.text.*,java.io.*,javax.swing.filechooser.FileFilter"

<br>
<%=(new java.util.Date())%>
<%
String startPath = "../webapps/ATServlets/data/mti";
File myDir = new File(startPath);
String myPath = myDir.getCanonicalPath();
out.println("<br><br><br>Results of Query Path: <br>" myPath "<br><br>");
String[] filelist = myDir.list();
out.println("<br>");
out.println("<center>");
out.println("<table BORDER COLS=1 width=400>");
String urlPath = null;
String hrefPath = null;
for (int i=0; i<filelist.length; i++)
urlPath = new String("\"http://judy:8080/ATServlets/jsp/xmlfetch.jsp?filename="+filelist[i]+ "\"");
hrefPath = new String("<a href=" urlPath ">");
out.println("<tr><td><center>");
out.println(hrefPath + filelist[i] + "</a>");
out.println("</center></td></tr>");
out.println("</table>");
out.println("</center>");
%>
</center>
</body>
</html>
This first page resulted in source as follows:
NOTICE that the second jsp page is the HREF and I am using "filename" as the parameter key and the value is assigned (without quotes) to be the filelist entry.

OK Now here is the second jsp file (xmlfetch.jsp) that is fired up after the table selection. This file creates a stream to the Java Webstart plugin and tries to use the passed parameter as 1 of 3 arguments to the application (see last few lines). The variable fname is used to hold the contents of the getParameter() method.
<%@ page
contentType="application/x-java-jnlp-file"
info="myjnlp"
import="java.lang.*,java.text.*,java.io.*"
%>
<%
StringBuffer fname = new StringBuffer();
fname.append(request.getParameter("filename"));
//fname.append("MtiOutput.xml");
//out.println("the fname var = " +fname);
StringBuffer cBase = new StringBuffer();
cBase.append(!request.isSecure() ? "http://" : "https://");
cBase.append(request.getServerName());
if(request.getServerPort() != (request.isSecure() ? 80 : 443))
cBase.append(':');
cBase.append(request.getServerPort());
StringBuffer httpref = new StringBuffer();
httpref = cBase;
httpref.append(request.getRequestURI());
StringBuffer cBase2 = new StringBuffer();
cBase2.append(!request.isSecure() ? "http://" : "https://");
cBase2.append(request.getServerName());
if(request.getServerPort() != (request.isSecure() ? 80 : 443))
cBase2.append(':');
cBase2.append("80");
cBase2.append('/');
cBase2.append("ATJava");

Null values coming from JSON

Ok. heres whats going on. I have a bunch of charts all with
two series , demand and baseline. About half of them have a null
value for the last value in demand and of the half 2 have null for
the entire baseline.
my problem is one of the afore mentioned 2 charts will not
show up (chart shows but without lines) unless I iterate through
and set all null values to zero in the baseline series. Then
baseline will lie on the x axis(BAD) and demand will show
correctly(missing the last value because it null, GOOD)
my question is why? why does demand disappear when baseline
values are null? here is some code to maybe help you out

keep in mind this is only one panel theres about 9 and all of
them work as expected and the code is all the same.
any ideas?

no one has any ideas?
