Problem of generation of XML?
Hi, I'm relatively new to Flex 2 and I have a question.I am generating a view of oracle xml file and I hope to use it as a base for a grid of data in the chart.
My generation yields process data something like this:
< list >
< product name = 'Laptop' total = '0' >
< name of the warehouse = onhand 'California' = "10" / >
< name of the warehouse = onhand "Virginia" = "20" / >
< name of the warehouse = onhand 'Washington' = '0' / >
< / product >
< product name = "Desktop computer" total = '0' >
< name of the warehouse = onhand 'Washington' = '9' / >
< / product >
< / list >
I took this generated XML and put it in a local file for now.
When I try to load this data, I get this error:
TypeError: Error #1009: cannot access a property or method of a null object reference.

My mxml file looks like this:
<? XML version = "1.0" encoding = "utf-8"? >

I wonder if something is wrong with my generated xml data or if his thing. I noticed that my generation xml product still not 3 labels warehouse for each product. Could be the problem?
Also, the reason for which the label of the products of total is always 0 in the xml file is because this information is not in the view... I use mxml to calculate that.
Thank you!
It seems that I played with him for a while and that fixed it. The problem was my xml data and format that my httpservice returned. First of all my xml data to be surrounded and no Tags no and
tags. Then my httpservice to be a result of e4x format. It also made me to change how I manage myself properties individual xml data.
In any case, the fixed code looks like this for anyone who cares and got a similar error.
Import mx.collections.XMLListCollection;
Mx.rpc.events import. *;
[Bindable]
private var commodData:XMLList;
[Bindable]
public var slicedCommodData:XMLListCollection;
private function initApp (): void
{
SRV. Send();
}
private void resultHandler(event:ResultEvent):void
{
commodData = event.result.commodity;
slicedCommodData = new XMLListCollection (commodData);
var commodTotal:Number;
var nextNum:Number;
for (var x: Number = 0; x)< commoddata.length();="">
{
var warehouses: XMLList = commodData [x] .warehouse as XMLList;
commodTotal = 0;
for (var j: Number = 0; j< warehouses.length();="">
{
nextNum = 0;
nextNum = new Number (warehouses [j] .@onhand);
commodTotal = commodTotal + nextNum;
}
var firstItem:Object = slicedCommodData.getItemAt (i);
firstItem.@total = commodTotal;
}
}

Thanks for all your help!

Problem with XMLSerialize / indented XML
My problem is that my XML output is only a line like:
<? XML version = "1.0" encoding = "ISO-8859-15? > < rss version = "2.0" > < channel > < title > Test < / title > < / channel > < / rss >

Select xmlserialize (DOCUMENT xmltype (' <? xml version = "1.0" encoding = "ISO-8859-15"? > < rss version = "2.0" > < channel > < title > Test < /titre > < / channel > < / rss > ')) twice;

Ive been trying and just can't understand it. Thus, each section formularies its unique values.
Thanks for any help.A similar technique that your previous question - deduplicate each section by itself:
select xmlelement( app , xmlattributes('VTEST' as name) , xmlelement( web , xmlforest( ( select xmlagg(xmlelement(order_number,order_number) order by order_number) from ( select distinct order_number from vtest ) ) as order_numbers , ( select xmlagg(xmlelement(part_number,part_number) order by part_number) from ( select distinct part_number from vtest ) ) as part_numbers /* etc */ ) ) ) from dual /I just got the order_numbers and part_numbers and leave the rest for you ;-)
Maybe it's not the most effective method that it accesses the table several times. But xmlagg does not support a 'distinct' clause, as for example to count (distinct order_number), so I can't think offhand of a more effective solution.
Maybe if you are very strong to create XLS stylesheets to transform your original XML output for output desired using XQuery - then perhaps it could be done without access to the table several times. But probably it would be more effective anyway, because it would then do a job a lot of in-memory (or TEMP).

Problem of generation of Sync trigger in several synchronization USRP RIO 2943R problem
Generation problem shutter Sync in several synchronization USRP RIO 2943R problem.
Previous SR you may already know I'm stacked in USRP RIO multiple synchronization problem, especially in the mode based on the signal. Now I can cut down, the problem is mainly due to the outbreak of sync signals generation.
First of all, I read the article and the discussion in the following two links:
http://forums.NI.com/T5/USRP-software-radio/how-to-synchronize-multiple-USRP-Rio-294x-devices/TD-p/3...
http://zone.NI.com/reference/en-XX/help/373380D-01/usrphelp/synchronization/and I did my connection of the material according to the suggestions in the second link. My system schematic is shown in the following image:
I checked OctColck and SMU 6674 T connections. They are all connected correctly and the cable are fine. I use the niUsrpRio200_XcvrSyncPps.lvbitx.
According to the description of documents and discussion forum, the USRP RIO 1st in the list of devices are considered to be the USRP Master. Then, the FPGA to master USRP RIO released "trigger of sync" signal through the 'PPS Trigger Out' SMA port in RIO USRP box.
Based on the my analysis of the system, the first impression I have is the USRP Master does not export the 'sync trigger' correctly. The host VI reports the error like this:I was trying to measure the "synchronization trigger" using oscilloscope, but I found that it is impossible, because the host VI can not yet run, so there is that no signal can be seen from port 'PPS Trigger OUT.
So I think that if I can watch this signal "sync trigger" in home VI by importing this signal from FPGA to host VI. I did some changes on the FPGA VI as shown in the following image to watch this signal of façade of the host VI. but not so successful. the rx.start tragger relaxation and tx.start do not appear on the host vi read/write control function.

problem with getting some xml UTF-8 characters
Hello
Please help me solve the following problem. I need to parse the XML string that contains the currency symbol (for example pound sign, see the code example). In the result of the variable currSign contains '? What's wrong?
{} public static Sub test()
try {}
String data ="" +
"
0.00 ";ByteArrayInputStream is = new ByteArrayInputStream (data.getBytes ());
DocumentBuilderFactory plant = DocumentBuilderFactory.newInstance ();
DocumentBuilder builder = factory.newDocumentBuilder ();
Doc document = builder.parse (is);
Root element = doc.getDocumentElement ();
String currSign = root.getAttributes () .getNamedItem ("unit"). getNodeValue();
}
catch (Exception e) {}
}
}
Ah. I think I see the problem. You want to convert the string into a byte array data using the version without getBytes() argument. Which uses the default encoding (which is ISO-8859-1). You must call getBytes ("UTF-8") or specify ISO-8859-1 for the xml declaration.

ColdFusion 10 problem with cfhttp postype xml
We do a cfhttp call.
We submit xml data. We are able to send information from Server A to Server B, but Server B gives us no answer.
Our code works for coldfusion 8 and 9, but it does not work for coldfusionh 10.
This is the snippet of code
"< cfhttp method = 'post' url =" "#httpURL #" timeout = "3000" useragent = "#CGI.http_user_agent #" >
< cfhttpparam type = "XML" value = "" #xmlRequest # "name ="CLRCMRC_XML">"
< / cfhttp >
The content of server B can be access by
< cfdump var = '#cfhttp. FileContent #">."
Note This works in coldfusion 8 and 9, but we get all the data from Server B using coldfusion 10
Problem solved.
It was to change this line
to use the PROTOCOL = '1 '.

Dear all
I have a requirement to generate the XML data as shown in the light of the definition of XML schema. I did it by using oracle developer report to generate put them in the xml document.
My question is that it is important to attribute sequences for example
XSD has attribute
------------------------
Name
Address
phoneno
------------------------
But when I generate the XML using oracle report developer he changes the order of the attributes like this
-------------------------
phoneno
address
name
------------------------
Please guide this poor sequence of attribute have a problem during the validation of xml with xsd document.
ConcerningXML 1.0 specification:
http://www.w3.org/TR/REC-xml/#sec-StartTags
The name the start end-tags and gives the type of the element. [Definition: the name-AttValue pairs are referred to as the specification of attribute of the element], [definition: with the name in each pair referred to as the attribute name] and [definition: the content of the AttValue (the text between the "or"delimiters) as the attribute value.] Note that the order of specification of attribute in a start tag or empty element tag is not significant.

Problem with dynamic arrays, XML and JavaScript patterns
With the applied XML schema my JavaScript does not correctly work when it is added a 2nd row at my dynamic table. Instead of an added empty line 1st row data is copied on the 2nd line and if you change the data in the 2nd row it modifies data in the 1st row also. It works fine if the XML schema data connection is well removed.
No idea what I can do to get this working with the schema that is applied in the same way, it works without the schema?
Thanks for your help,

Help in what concerns the generation of XML using SQL/XML
I wrote the following SQL to generate a XML report. Tb_ken_lg_mstr of the table is the primary table of the workforce. Tb_ken_loans_base and tb_ken_cards_base tables are tables containing the cards and loans to sales by sales in tb_ken_lg_mstr people.
The problems that I face, is that:
1. even when there are sales people have not made a sale, that is, they have no documents tb_ken_cards_base and tb_ken_loans_base, yet their records are appearing the XML. I want to avoid this and only dirty people who have the list sales. A workaround is to use NOT EXISTS in the outer query more with tb_ken_lg_mstr. Is there a better way?
2 can anyone confirm that the approach used to combine the tables tb_ken_cards_base and tb_ken_loans_base is correct or not. Basically, I want to publish a report of sales person (tb_ken_lg_mstr) and all its sales (tb_ken_cards_base and tb_ken_loans_base).
3. the XML output is coming in a single line rather than in a hierarchical format.
I use 10.2 g

What I don't understand is why Oracle is picking up Sales_Codes missing in tb_ken_loans_base or tb_ken_cards_base, even if I do an inner join?
You do not have an inner join, you only access TB_KEN_LG_MSTR in the main query.
What you do in the SELECT part are scalar subqueries just on each of your tables of the child, who is unable to filter the main table in the first place.NOT EXISTS is indeed a solution, or consider doing all of the joins in the FROM clause, as I suggested above, like this:
... FROM TB_KEN_LG_MSTR c LEFT OUTER JOIN tb_ken_cards_base a ON a.sales_code = c.sales_code LEFT OUTER JOIN tb_ken_loans_base b ON b.sales_code = c.sales_code WHERE a.sales_code IS NOT NULL OR b.sales_code IS NOT NULL ...But then the subgroups becomes more difficult with this approach.
Regarding the third question, how I format in Oracle? If not possible in Oracle then what other ways are?
10.2, you can use this trick to format the output:
SELECT xmlelement( ... ).extract('/*').getClobVal() FROM ... -
Problem with loading of XML document
Hello
I have to load XML document uploaded on the web in XML DB and validate against the schema. The problem is, that:
schemaLocation still looks like in the document like this:
P1:schemaLocation = "SPDS. IFR.i009.pl http://inetsqlcg:82/ReportServer?%2fReportPublisher%2fspds.ifr.009.PL & amp; rs 3aFormat % = XML & amp; rc % 3aSchema = True'
and cannot be changed.
I registered schema by using the command:
BEGIN
DBMS_XMLSCHEMA.registerSchema
(
SCHEMAURL = >
-UTL_URL. UNESCAPE
('http://inetsqlcg:82/ReportServer?%2fReportPublisher%2fspds.ifr.009.PL & amp; rs 3aFormat % = XML & amp; % 3aSchema rc = True'),
SCHEMADOC = > BFILENAME ("TEST_DIR',"test.xsd").
FORCE = > TRUE
);
END;
(ORACLE inquired about the variable & amp, I set myself to & amp course :)))
I used the FORCE to omit the error:
ORA-31000: resource ' http://inetsqlcg:82/ReportServer?/ReportPublisher/spds.ifr.009.PL & amp; RS: Format = XML & amp; RC:schema = True' is not a document of schema XDB
Now I have the schema with SCHEMA_URL
Select SCHEMA_URL in the user_xml_schemas;
http://inetsqlcg:82/ReportServer?%2fReportPublisher%2fspds.IFR.009.pl & amp; RS % 3aFormat = XML & amp; RC % 3aSchema = true
but when I try to load the document like this
INSERT INTO THE REP
VALUES
(
XMLType
(
BFILENAME ("TEST_DIR", "test.xml"),
NLS_CHARSET_ID ("AL32UTF8")
)
);
There is an error:
ORA-19007: Schema - does not http://inetsqlcg:82/ReportServer?%2fReportPublisher%2fspds.ifr.009.PL & amp; rs 3aFormat % = XML & amp; % 3aSchema rc = True expected.

Version of the database is:
11.1.0.7.0
but probably I'll have to do the same thing on 10.2.0.3.0
Any suggestion, please.
And thanks in advance.Looks like we cannot manage this value of the schema location indicator... Not even sure we should, to be honest...
You can use a workaround like this...
