Read a XML node value/attribute value from a CLOB
Hello,
I can write SQL/ - PL/SQL "straightforward" but now I have a problem what is to big for me. I hop that someone can help.
We create by code a xml structure and write these into the oracle database CLOB field. I'm sorry to say that a xml text structure is written into a clob in stead of a xmltype field. (it's a design failure?) It's a large xml structure. I believe I can't attach a file so I put at the end of this discussion a light example of the xml structure.
It's a xml with quartervalue's, so there are 35040 detail rows (24h * 4 * 365days). I want to accumulate the the attribute Amount value 9. The amount value is in the Detail node a attribute but at the end you can see that for the DST are also 4 value's, but these are not attribute value's but node value's. (In this case it are four value's in some cases there is one DST amount value.
Can somebody help me how to accumulate all the detail attribute value Amount with the node value Amount of the DST tag?

From what I know, extracting the "Amount" values in the Details section and the "Amount" values in the DSTS section would be two different SELECT statements.
Both of these will use XMLTable() to extract the values.
BTW - If you need more information on this, post up in the XML/XML DB forum section for more complex help. (eg getting YEAR with the DSTS Amount values)
as far as XML size goes, I've seen oracle handle a 100MB XML document without problems.
(just understand, it will be 'slow')
This one will give you the Amount values from the DSTS section:
with xml_data as ( SELECT

Remove xml node based on value
Hi,
we have to remove elements bases on the value.
for example consider below xml
<htl:room>
<htl:ratePlan>
<htl:freeNights>12</htl:freeNights>
<htl:promoSavings>undefined</htl:promoSavings>
<htl:tax>undefined</htl:tax>
</htl:ratePlan>
<htl:guestAllocation>1,2</htl:guestAllocation>
</htl:room>
We have to remove elements with value undefined and should construct a new xml as below
<htl:room>
<htl:ratePlan>
<htl:freeNights>12</htl:freeNights>
</htl:ratePlan>
<htl:guestAllocation>1,2</htl:guestAllocation>
</htl:room>
please help.

select 'aaa','a1',0 from dual union all
select 'bbb','b1',0 from dual union all
select 'ccc','c1',0 from dual union all

aaa a1 10
bbb b1 0

dcc d1 11to find the other is just a minus

How to read a xml node name in xsl? Urgent!
Hi,
I've a dynamic xml which gets generated at runtime. The basic nodes remain same but the content and nodes vary.
- <root>
- <list>
- <row>
<courseStartDate></courseStartDate>
<courseEndDate></courseEndDate>
<courseName>ORACLE</courseName>
</row>
- </list>
</root>
I have an xsl which would read the values
as :
<xsl:value-of select="courseStartDate"/>
I would like to know if its possible to read the node name "courseStartDate" through xsl, which could be stored in a variable and then the corresponding value could be retrieved??
ThanksIf u want to display the name : value then u can do like this
<xsl:eval>this.selectSingleNode("name").nodeName</xsl:eval> : <xsl:value-of select="name" /> -
Search the xml node by attributes and display the entire row
I am having a table with two columns say
school_name string type
student_notebookprice xmldata
how do i search with oracle query having student_id=102 and schoolname="abc_school" with notebook price 20, how do i get only one single row
abc_school,
<students>
<student id="101">
<notebookprice>12</notebookprice>
</student>
<student id="102">
<notebookprice>20</notebookprice>

</student>
<student id="302">
<notebookprice>15</notebookprice>
<notebookprice>16</notebookprice>

</students>yes . what i want based on search criteria i need to display that row . initially i have tried with the below query
SELECT school_name,
extractvalue(value(x), '//id') as student_id ,
extractValue(value(x), '//teacher') AS teacher
FROM school t ,
TABLE( XMLSequence( Extract(t.obj_xml, '/students/student[id=101 and teacher="abc"]'))) x
where existsNode(t.obj_xml, '/students/student[id=101 and teacher="abc"]') = 1
but when i want to add the second student in the search , i am failed to produce the second student information in the output and i can able to add it to where clause and but how to display the student info in the output . The xmltable option that u have specified looks good but what i fear is , it produce multiple combination with all the tags in the xml with the other columns in the table . will it cause any performence issue .
<students>
<student >
<id>101</id>
<teacher>abc</teacher>

How can I read an XML string that's not from an XML file?
I've got a script I'm trying to setup that communicates over a socket to retrieve different directions from a custom built Java program. The Java program listens to requests from the Adobe scripting engine (in my case it's a Photoshop script) on a socket and immediately responds with the next set of directions. These directions are currently in XML format. The issue I'm having is that I can't parse the XML data since it's entered into a new XML object from a string rather than being read from a file. Even without the socket code, you can see the issue by doing the following:
var xml = new XML("<test><data>hey!</data></test>");
alert(xml.test.data);
alert(xml);
The first alert "should" return "hey!" (without quotes, of course), but it doesn't, while the second alert returns what you would expect it to:
<test>
<data>hey!</data>
</test>
It works fine if read from an XML file, but from a string, like shown above, it just presents an empty alert box when attempting to access "xml.test.data". Any ideas on how to fix this issue? Can it be fixed? Has it been fixed in newer versions (I'm currently using CS4)?
Thanks in advance for any help!Duh... found my error... I was attempting to access the data by referencing the created "root" element. Since <test> is the very first element tag, it's setup as the root element, which you don't need to reference. Changing the alert to alert(xml.data); fixed it.
Now I just feel dumb, lol... -
Select XML Node by a specific attribute value
I am newbie for LifeCyle.
This might be an easy question, but it really got me here.
I am trying bind xml data into a Drop-Down List. The databinding is working fine, but I would like to have more specific node selected from the xml file by using a attribute value.
for example Code in AS 3.0
root.node.(@id=="1").subNode
How could i do the same thing in LifeCycle Designer 8.0
Thank you in advance!!!there's no native method for this, maybe you should create some functions for this. just like
private function setAttribute(node:XML, name:String, value:String, index:int = -1):void
var attrs:XMLList = node.attributes().copy(),
l:int = attrs.length();
if(index == -1 || index > l - 1)
node.@[name] = value;
else
delete node.@*;
var idx:int = 0;
for (var i:int = 0; i < l + 1; i++)
if(i == index)
node.@[name] = value;
else
var attr:XML = attrs[idx];
node.@[attr.name()] = attr.toString();
idx++;
and use it like this:
setAttribute(myNode, "otherAttribute", "abc", 0); -
How to read data from a value attribute
I have a context node which has some value attributes.the value to these attributes have been set in their setter/getter methods . How do i read data in the do_prepare_output ,because this attribute does not get recognised when i do get_property_as_string( iv_attr_name = 'XYZ' ). Please let me know how this can be done .
Hi Shakuntala,
Value attributes are only for display purpose.
Check where is the value for the Value Attribute you are trying to read getting stored in SET method.
For example, Employee Responsible has a value attribute RESPONSIBLE_NAME_UI on the screen
but in turn the value gets stored in the 'RESPONSIBLE_NAME' and 'RESPONSIBLE_TEXT'.
You can get these fields in SET method.
Now when you want to read, use the logic available in GET method for the value attribute like this
value = me->get_responsible_text( attribute_path = '//TRADE/RESPONSIBLE_TEXT' ).
IF value IS INITIAL.
value = me->get_responsible_name( attribute_path = '//TRADE/RESPONSIBLE_NAME' ).
ENDIF.

Issues In Reading Attribute Values From Master Data
Hi All,
I have a requirement where, i need to read an attribute value from master data. I have a characteristic YCSTATMCG (AT Cost Group Code) which is the master data from where i have to read the attribute, 0PROFIT_CTR (Profit Center). The attribute thus read, has to be populated into another characteristic, YPROFIT_C. But YCSTATMCG referes to another characteristic, YCSTCG. Here is the FOX Code I wrote with YPROFIT_C as the changing characteristic and 0AMOUNT as keyfigure.
DATA V_ATCP TYPE YCSTATMCG.
DATA V_PROFIT TYPE YPROFIT_C.
DATA V_PROFITC TYPE YPROFIT_C.
DATA V_AMOUNT TYPE F.
V_ATCP = OBJV().
MESSAGE I020(YCO_CFT) WITH V_ATCP.
V_AMOUNT = {0AMOUNT, # }.
V_PROFIT = ATRV('0PROFIT_CTR' , V_ATCP).
MESSAGE I020(YCO_CFT) WITH V_PROFIT.
{0AMOUNT, V_PROFIT} = V_AMOUNT.
But this is not working. The ATRV() function is not reading the attribute values at all. Any solutions and suggestions is highly valued.
Thanks in advance
SwaroopHi,
even i have the same situation.
i just want the attribute value of a char to be populated into another characteristic in the planning query.
my question is whether i should populate the keyfigure field also in the FOX code.
if so should i populate both 0amount and 0quantity fields as i have 2 keyfigure fields.
Thanks for your help

i need to get value from "Web Tier->JSF\Facelets->page"
is there any help please?You should try Franks generic selectionListener http://www.oracle.com/technetwork/developer-tools/adf/learnmore/25-generic-tree-selection-listener-169164.pdf.

How to get attribute value of a node
Hi experts
I have a mapped node in my view context from component controller context. This node consists of 2 value attributes inside
Example:
NODE1 -
> Cardinality 1..1, seleciton 1..1
-- x_date -
> type DATS
-- x_years -
> dec3
How do I get the attribute value attr1 and attr2 ??
Here is my code in my view method
DATA: lr_node_info TYPE REF TO if_wd_context_node_info,
l_date TYPE dats,
l_xyears TYPE i.
lr_node_info = wd_context->get_node_info( ).
lr_node_info = lr_node_info->get_child_node('NODE1').
l_date = lr_node_info->get_attribute( name = 'X_DATE' ).
l_xyears = lr_node_info->get_attribute( name = 'X_YEARS' ).
It does not seems to work since it says < the result type of the function method can not be converted into the result type L_DATE>
I try to understand why but not sucessful, please help and thank you for your kindnessHi Dean,
Regading uour problem of reading the attributes value of the context node, you have to use the code wizard. that ia avaliable on the top toolbar when you are inside the View Method
There is option to read context select that radio button option and then thru F4 help
if you can select the node then Code is automatically generated with variable declaration.!!
Like this :
DATA lo_nd_node1 TYPE REF TO if_wd_context_node.
DATA lo_el_node1 TYPE REF TO if_wd_context_element.
DATA ls_node1 TYPE wd_this->element_node1.
DATA lv_x_date LIKE ls_node1-x_date.
DATA lv_x_year LIKE ls_node1-x_year.
navigate from <CONTEXT> to <NODE1> via lead selection
lo_nd_node1 = wd_context->get_child_node( name = wd_this->wdctx_node1 ).
get element via lead selection
lo_el_node1 = lo_nd_node1->get_element( ).
get all declared attributes
lo_el_node1->get_static_attributes(
IMPORTING
static_attributes = ls_node1 ).
lv_x_date = ls_node1-x_date.
lv_x_date = ls_noe1-x_year.
if you can select the attribute then Code is automatically generated with variable declaration.!!
DATA lo_nd_node1 TYPE REF TO if_wd_context_node.
DATA lo_el_node1 TYPE REF TO if_wd_context_element.
DATA ls_node1 TYPE wd_this->element_node1.
DATA lv_x_date LIKE ls_node1-x_date.
navigate from <CONTEXT> to <NODE1> via lead selection
lo_nd_node1 = wd_context->get_child_node( name = wd_this->wdctx_node1 ).
get element via lead selection
lo_el_node1 = lo_nd_node1->get_element( ).
get single attribute
lo_el_node1->get_attribute(
EXPORTING
name = `X_DATE`
IMPORTING
value = lv_x_date ).
Hopes this will helps you.

XML-22009: (Error) Attribute 'select' not found in 'xsl:value-of'
Hello,
I'm a long-time Siebel developer but novice to BIP, trying to enhance some complex rtf templates that an experienced xdo/bip developer (contractor) designed for us in the past, with a couple of new fields that have been added to the integration object.
All templates and sub-templates receive 'no errors found' when using add-in tool selection of 'Validate Template'. Unfortunately we cannot utilize the 'preview' capability due to the way the sub-templates are called, so only way to test is to upload into server and attempt to run real-time.
This results in UI error of SBL-OMS-00203, which when we dig into the xdo log file turns out to be:
<Line 648, Column 88>: XML-22009: (Error) Attribute 'select' not found in 'xsl:value-of'.
I have exported all templates and sub-templates into XSL-FO Style Sheet and looked at line 648 column 88, and none of them seem to correspond to this line/column combination (in fact most exports do not even go that high in lines).
Googling 'XML-22009' hasn't proven to be of much help, so reaching out to the xdo experts in this forum.
How are the line/column #'s determined in the xdo log output?
I am pretty sure that it must be some issue with my 'Main' template, since none of the sub-templates have been changed (and the current version of the report, without the new fields incorporated, still runs fine from the UI). In the XSL-FO format export of the (modified, with new fields added) 'Main.rtf' file, line 648 places it right in the midst of a bunch of hex which corresponds to an imbedded image (which was also part of the existing template, no change there) and that line only has 65 columns (i.e. doesn't even go up to 88), so I'm questioning how valid the Line/Column information is in the xdo log error message.
Any hints on troubleshooting this one would be greatly appreciated!
Thanks & Regards,
KatrinaHi,
as I wrote in the inital message, we even left out the output method or used "application/pdf". The result is unfortunately always the same. And I still claim this is not a problem with the stylesheet itself, it has to do something with the mobile's environment.
Something I didn't tell: we have 2 servlets in our application, 1 responsible for output in html and 1 in pdf. The .fo stylesheet passed to the 'html servlet' is parsed correctly (and shows the source code, because it does not know about fo and conversion to pdf), the .xsl stylesheet passed to the 'pdf servlet' raises same exception/same line. You might tell us that there is a problem with the 'pdf servlet', but once again: why in online it is working?
Greetings and thanx very much for your precious time! -
Protecting the attribute value from getting reset!
Hello all,
I have attached a custom drop down search help to the attribute "SERVICE_UNIT_NAME" in the "BTPARTNERSET" context node. The drop down list contains a blank entry as well as a couple of other entries, I have placed a create object statement for my search help class in the Getter method "GET_V_SERVICE_UNIT_NAME" while written the following code in the setter method "GET_P_SERVICE_UNIT_NAME" as suggested by one of the esteemed experts here on the forum.
case iv_property.
when if_bsp_wd_model_setter_getter=>fp_fieldtype.
rv_value = cl_bsp_dlc_view_descriptor=>field_type_picklist.
endcase.
This drop down list is showing correctly, however my problem is that if the user selects any value from the drop down list, the selected value gets copied to the attribute but when ever the user press an "ENTER KEY" or any other action, the value in the attribute gets initialized to the first value in the drop down list which is a "BLANK" value. I want to preserve the value originally selected by the user from the drop down list, without it being reset by any other user actions on the screen. Do I need to redefine any other method for this attribute? I'll appreciate any help.
Regards,Naresh and Sumit, many thanks for your valuable inputs however, I have tried your code but I am still facing the same issue, as the attribute value for "SERVICE_UNIT_NAME" is getting refresh every time an "ENTER" is pressed on the page. Let me specify some other detail that may help in understanding this behaviour for the attribute value, actually when on the initial page, user has to enter his phone no / network ID, so that the standard functionality bring about the city, postal code, country etc. so once these values are set in the related attributes, the user will click on the incident button, which brings about a search help (web dialogue) for partner selection, so any value selected, is displayed afterwards in the "SERVICE_UNIT_NAME" attribute on the next page. However, after putting the custom drop down list at the said attribute, the value selected on the previous page is not populating in the attribute and the user can select the value from the custom drop down list now, but once he press "ENTER" or pushes any other button the page, the selected value in the attribute gets initialized. Is there a way to check for the user input?
