Hi,
I would suggest that you use a more simple library like Dom4j,
It is quite easy to use and is proven to have good performance on heavy tasks.
you can access xml attributes with a single line cod :
String value = element.attributeValue("Attribute name");you can download and view samples here : http://dom4j.sourceforge.net/

Help needed reading xml attributes

I have a method that is reading through my XML doc and pulling out all of the elements. I want to get it to pull out the href attribute from within AdvertText but can't figure out how to do it within my method. Any help would be greatly appreciated!
Here is the sample of the xml:
<Advert groupName="Advert" type="group">
<AdvertText dataType="RawString" fieldName="AdvertText" href="http://boston.craigslist.org/nos/abo/583827823.html" originalElement="a" type="field">First Floor Central Gloucester -</AdvertText>

Read XML attributes from RSS internet link

I am very new to LabVIEW, and I am trying to determine the best way to read information an RSS link. Specfically, I would like to read data from a Yahoo! Weather RSS like http://weather.yahooapis.com/forecastrss?w=2502265. I would like to extract the temperature from <yweather: condition temp="[##]>, the wind speed from <yweather:wind speed="[##]">, and the text description from <yweather:condition text="[text]".
I have looked into some XML parsing solutions like EasyXML, but I wonder if they are too much for what may be a simple task. I would appreciate any input on my current problem. Thanks.

Howdy,
It looks like EasyXML would make you life a little easier. You can search the LabVIEW Example Finder (Help menu->Find Examples) for XML examples. Other than that you would have to navigate to the website and parse the website source and use the LabVIW String Functions.

Any one tell me, i want to display the ids in the margin. i read xml attribute, but i didn't know how to display to the margin. Help me.

One way of doing that is to use JDOM...

Hi,
As you may be aware, LONG datatype is obsolete for quite some time now.
If you can you should really consider migrating it to CLOB, or in this specific case store XML data in an XMLType column.
In particular, we can't use XMLType constructor directly on a LONG.
Here's a simple PL/SQL solution though, provided the data is not larger than 32k :
SQL> create table test_long (xmldoc long);
Table created
SQL> insert into test_long values('<?xml version="1.0" encoding="UTF-8" standalone="no"?>
2 <!DOCTYPE labels SYSTEM "label.dtd">
3 <labels _QUANTITY="1" _JOBNAME="LBL213685">
4 <label _FORMAT="XE_INSP_REQ_LBL.lwl">
5 <variable name= "L_DATE">04-JAN-2012</variable>
6 <variable name= "L_TIME">10:45:17</variable>
7 <variable name= "L_LPN">K01-4713BE</variable>
8 <variable name= "L_ITEM">XXXXWT88-002</variable>
9 <variable name= "L_ITEMDESC">SPRING,REVERSIBLE EXPANSION GE14 234C6745P001 REV.01</variable>
10 <variable name= "L_QTY">1</variable>
11 <variable name= "L_POREV"></variable>
12 <variable name= "L_PONUM">837037254</variable>
13 <variable name= "L_ITEMREF">834C6745P001</variable>
14 <variable name= "L_PROJECT"></variable>
15 <variable name= "L_ISIS"></variable>
16 <variable name= "L_LABEL">1</variable>
17 <variable name= "L_LINE_NO">1</variable>

hi,
U r retriving the elements by tag name.So it just chks the tag name ie.<book> & gives u array of elements.But u need retrive d attribute of <book> tag itself.
=Solution =====
Add one more statement ----> var[]= doc.getElementsByName("book");
Now u hav book elements as an array & can retrive id in for loop
for(var; var.length;var++)
doc.element[var].id.value

What my program do is to get the encoding of XML files and convert them to UTF-8 encoding files, while I need this "encoding" information of the original XML document thus I can convert...
After reading specifications and JDOM docs, the truth turns to be disappointed, no function is provided to get this information in JDOM level 2(the current released one), while it's promissed that this function will be provided in JDOM level API....
Thanx all for your help and attention!!!

How to read the attribute in mapping..

Hi,
My source XML looks like this
<GLDEBITACCT>
            <VALUE>0545-K-2006605-5500001</VALUE>
            <GLCOMP glorder="0">0545</GLCOMP>
            <GLCOMP glorder="1">K</GLCOMP>
            <GLCOMP glorder="2">2006605</GLCOMP>
            <GLCOMP glorder="3">5500001</GLCOMP>
</GLDEBITACCT>
Where glorder is the attribute of GLCOMP. Now I have requirement to read the attribute ( atleast 2 of them)
I have to map to target field checking the value in glorder="1
For e.g. with above XML, if the value in glorder="1 is K than map value from glorder="2 (2006605) to Target 1.
IF the glorder="1 is P map the value in glorder="2 to Target 2 and goes on for another one
How can i acheive this mapping. When I tried putting the value of glorder, i am not getting anything.
Regards,

Hi,
You can use below UDF. Please make sure to select context parameter while creating UDF. There will be 3 input arguments for this function:
1. GLCOMP (a)
2 @glorder   (b)
3 Constant   (c) --depending upon the target node
Also conext of attribute @glorder should be same as that of GLCOMP.
//write your code here
for(int i=0;i<a.length;i++)
    if(b<i>.equals("1")&&c[0].equals(a<i>))
    for(int j=0;j<a.length;j++)
          if(b[j].equals("2"))
     result.addValue(a[j].toString());
                        break;
For target node target1 use K as 3rd argument, for target node target2 use P and so on.
Let me know how it works.
Regards,
Anirudh.

Getting at a top-level XML attribute

It's Friday afternoon... I'm fried and can't seem to figure
out how to get at a top-level XML attribute.
Some specifics...
My XML doc has a single attribute in the top node followed by
several "version" nodes
<projData projectName="Spry Project">
<version>
I successfully load and create an xml data set from said XML
file. Later on, I use the getDocument() method to refer to the XML
DOM doc used by the original xml data set. I need to extract the
value of the attribute "projectName" into a javascript variable.
The xpath query should be "projData/@projectName" but all I
get returned is an undefined value.
Any ideas? I'm sure it's something simple that I'm
overlooking.

> can you please helo.
This is impossible.
Obviously your ABAP mapping is wrong. Fix it.

How to read XML data stored in CLOB in Concurrent prog Output

Hi All,
I'm trying to Generate the XML Data as concurrent Program output. I have a PL/SQL package which generated the XML data by using SQL/XML functions. I'm storing the generated XML data in a CLOB variable. But when i try to read the data using fnd_file.put_line(fnd_file.OUTPUT,XML_Data) it doesn't display data more than 32767 bytes.
Please help me out to understand what could be done to read the data in chunks. I have tried many logic's to print chunks of data but the output tags are either chopped off and errors out saying Tag not found.
My logic is as below:
v_handler:= DBMS_XMLGEN.newContext(v_xml_query);
--Sets NULL handling options
DBMS_XMLGen.SetNullHandling(v_handler, dbms_xmlgen.EMPTY_TAG ) ;
--Set special character handling
DBMS_XMLGEN.setConvertSpecialChars(v_handler, TRUE);
-- Specified whether to use an XML attribute to indicate NULLness of particular entity in the XML document
DBMS_XMLGen.useNullAttributeIndicator(v_handler,TRUE);
-- set Checking invalid chars
DBMS_XMLGEN.setCheckInvalidChars(v_handler, TRUE);
-- get the xml data as required
v_xml_data:= DBMS_XMLGEN.getXMLtype(v_handler);
SELECT XMLROOT(v_xml_data.extract('/*'),VERSION '1.0').getClobVal() into v_new_xml_Data from dual;
-- get the length of the xml generated
v_clob_len := dbms_lob.getlength(v_new_xml_Data);
FND_FILE.PUT_LINE(FND_FILE.LOG,'The Clob length is :'|| v_clob_len);
-- logic to process string more than 32767 Processing by each character
v_offset :=1;
while (v_offset <= v_clob_len)
LOOP
v_char := dbms_lob.substr(v_new_xml_Data, 1, v_offset);
IF (v_char = CHR(10))
then
fnd_file.new_line(fnd_file.output, 1);
else
fnd_file.put(fnd_file.output, v_char);
end if;
v_offset := v_offset + 1;
END LOOP;
FND_FILE.PUT_LINE(FND_FILE.LOG,'The offset is :'|| v_offset);
FND_FILE.NEW_LINE(FND_FILE.OUTPUT, 1);
THe above logic is for character by character which is a performance burden? Please let me know if there is any other work around for this

Hi,
Thanks for Replying. I have refered http://blog.oraclecontractors.com/?p=69 and then i added that piece of code. Basically, i'm trying to generate a report using XML publisher. To generate the XML data i'm writing a pl/sql package with SQl/XML functions. DBMS_XMLGEN would help me convert the XML Data as is. When the concurrent program runs this XML data will merge with RTF layout and generate required report. I'm able to generate the Report for data less then 32767 bytes. More than the limit i need to pass chunks of XML data to read as output. That's the reason i'm using fnd_file.output. But it reads only 32767 size at a time.
WHen i use the given logic, it works perfectly fine, but it loops for each character, for example if you have 30,000 characters it loops the same, which is peformance burden.
So i tried to write the logic of chunks but still i get the error that XML tag is not found or missing. I'm hoping this is very common issue, but after all my trails, i didn't find the right solution.
the other logic i tried was :
v_new_xml_data varchar2(32767)
v_iterations := CEIL(v_clob_len/v_chunk_length); -- v_chunk_length is 32767 and v_clob_length is length of the XML data stored inthe clob variable
For i in 0..v_iterations
LOOP
FND_FILE.put_line (fnd_file.log,'the loops v_pos :'||i||' and v_clob_length :'||v_clob_len);
v_new_xml_data := DBMS_LOB.SUBSTR ( V_XML_DATA,v_chunk_length,(i*v_chunk_length)+1);
FND_FILE.PUT_LINE (FND_FILE.OUTPUT,v_new_xml_data); -- read the output for every 32767 chunks
FND_FILE.PUT_LINE(FND_FILE.LOG, 'Chunk length is :'||((i*v_chunk_length)+1));
END LOOP;
FND_FILE.put_line (fnd_file.log,'out of loop');
FND_FILE.put_line (fnd_file.log,'length of new xml is '||v_clob_len);
Please, let me know if you need Further clarifications on the same.

Read XML file from presentation server

Reading XML File from application server

Hi experts,
My aim is to read a XML file from application server and extract the relevant data from it and process further.
When I am trying to read a XML file from application server it is reading success fully but the problem is that its not reading the last root structure of XML file why is so happening can any body help me?
I am using the following code:
TYPES: BEGIN OF xml_line,
text(256) type x,
END OF xml_line.
DATA: e_file LIKE rlgrap-filename VALUE 'applcatin server path'
OPEN DATASET e_file FOR INPUT IN BINARY MODE.
IF sy-subrc EQ 0.
DO.
    READ DATASET e_file INTO wa_item1-text.
    IF sy-subrc EQ 0.
      APPEND wa_item1 TO gt_item1 .
      CLEAR wa_item1.
    ELSE.
      EXIT.
    ENDIF.
ENDDO.
ENDIF.
CLOSE DATASET e_file.
after this i am passing this internal table to "cl_ixml" class to extract the data
but it returning the itab with required value except the last record.
The stream reading the file it self is i thought in complete thats why it is not converting the all values.
Please help me...
Thanks a ton in advance.

Hi,
1 Copy Report BCCIIXMLT1
2 (you can change the way of filling internal table xml_table if necessary)
3 you don't need the part between
*-- render the DOM back into an output stream/internal table
and
*-- print the whole DOM tree as a list...
Comment it out or simply delete it
4 Rename form print_node to your liking e.g. process_node
5 In your new form you need three extra variables:
data: attribs type ref to IF_IXML_NAMED_NODE_MAP,
      attrib_node type ref to IF_IXML_NODE,
      attrib_value type string.
6 After the lines:
when if_ixml_node=>co_node_element.
string = pNode->get_name( ).
Insert:
attribs = pNode->get_attributes( ).
clear attrib_value.
case string.
when ''. "put your XML tag name here
    attrib_node = attribs->get_named_item(name = '' ). "put your XML attribute name here
    attrib_value = attrib_node->get_value( ).

File-Adapter: Variable substitution form payload XML-attribute

Hi experts,
is possible to use XML-attribute-content for variable substitution in file-Adapter?
extract from XML:
<?xml version="1.0" encoding="utf-8" ?>
- <all>
- <transaction <b>file="filename"</b>>
- <table name="BPAADDRESS" options="insertIfUpdateFails">
- <record id="1">
<hkeycol name="BPAMAINHKEY">0010500345</hkeycol>
<hkeycol name="USAGE">Invoice</hkeycol>
</transaction>
I want to get the value "filename" = attribute file of transaction.
Is this possible?
Thanks a lot,
Florian

I have done this taking a field from the XML.
You have to map the location of the field within the XML...
Taken from:
http://help.sap.com/saphelp_nw04/helpdata/en/bc/bb79d6061007419a081e58cbeaaf28/frameset.htm
Variable Substitution (Target Directory/File Name Scheme)
If you set the Enable indicator, you can enter variables for the Target Directory and File Name Scheme. Enter the names of the variables and references in the table.
●      Enter each variable that you reference in the Target Directory and File Name Scheme fields without the surrounding percentage sign under Name of Variables in the table.
The variables can refer to attributes of the message header or elements of the message payload.
○       If the variables are to refer to an attribute of the message header, add the prefix message: to the name of the variable under Reference. You can specify the following attributes of the message header:
sender_party, sender_service, receiver_party, receiver_service, interface_name, interface_namespace,
message_id (message ID with hyphens, for example 9fbe1ff1-9a0d-11d9-8665-cbf10a126331)
message_id_hex (message ID in hexadecimal format, for example 9fbe1ff19a0d11d98665cbf10a126331)
For example, if you want to specify the interface name from the message header in the target directory or in the file name scheme, enter message:interface_name as the reference.
If one of the message attributes contains characters that are not permitted in a file name, for example \, /, :, *, ?, ", <, >, |, then these characters are replaced by an underscore ("_").
○       If the variable refers to an element in XML schema, add the prefix payload: to the information under Reference. The reference then comprises a pseudo path description in the form of a comma-separated list with the schema namea,na,nameb,nb,....
namea,nameb,... corresponds to the element name and na,nb,... corresponds to the occurrence of the element name at the respective level in the document.
The description begins at the root of the document and ends at the respective element.
To reference the element that is in bold in the example, the following expression is used: payload:root,1,e1,1,e2,2
The parser searches for the first occurrence of the root element at the first level. It then searches for the first occurrence of e1 at the second level and for the second occurrence of e2 at the third level. The content of the last element (Example Value) is set as the value for a specified variable.
<?xml version="1.0" encoding="UTF-8" ?>
<root>
<dummy>
     <e1>
        <e2>Data_1</e2>
        <f/>
        <g attr="abc">text</g>
        <e2>Data_2</e2>
     </e1>
</dummy>
<e1>
     <e2>illegal/value</e2>
     <f/>
     <g attr="abc">text</g>
     <e2 attr="fghij">Example Value</e2>
</e1>
</root>
●      To disable the check the adapter performs for the element data, set the Disable Security Checks indicator.
Otherwise, the adapter checks whether the element data contains characters that could lead to security risks in the file system environment. The check includes the characters /, \, and ...

XML attributes as a response

My skills are rudimentary, I'm a new flex developer. I have
done all of the tutorials and examples and I'm just struggling with
using an XML attribute checking a response.
I've written a simple flex 3 app to talk to Asterisk AJAM.
I'm writing the login piece-- and i'm having trouble parsing this
response from an http service (successful login) my problem comes
in with the value not being as such
<item>valuehere</item> it's part of the tag, an
attribute i would suppose.:
<ajax-response>
<response type="object" id="unknown">
<generic response="Success" message="Authentication
accepted"/>
</response>
</ajax-response>
What I have is a simple app with a http service and a login
form. I have an event handler for the HTTP service, but I don't
know how to parse for that generic response tag. Anyone know how to
format an XML object for that type of response and throw a simple
if statement looking for that attribute?
Failure looks like this BTW:
<ajax-response>
−
<response type="object" id="unknown">
<generic response="Error" message="Authentication
failed"/>
</response>
</ajax-response>
Thank you,
Brian

I've came up with the following code trying to use XML
attributes from the response above--- it doesn't work but here is

trying to have it do an alert which doesn't work either):
