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.

Function module to read xml files from application server

Hi experts,
I need to read xml files from application server to sap. Is the any siutable function moldule for that?

Hi Cenosure,
Donno about FM which will upload data directly to SAP, I think you have to do some mapping for it so that it will suit the SAP format. Again it depends on your requirement..
Please elaborate more about your requirement.
Please have a look on below FM
TEXT_CONVERT_XML_TO_SAP
Also search on SCN there are many threads on the same topic available.
http://abapreports.blogspot.com/2008/09/upload-xml-file-from-application-server.html
This is the link which will give you the Code
http://www.geocities.com/rmtiwari/Resources/MySolutions/Dev/Codes/Report/Z_RMTIWARI_XML_TO_ABAP_46C.html
Use this XML file to Upload the same, this Program will work for your XML file also,
http://www.geocities.com/rmtiwari/Resources/MySolutions/Dev/Codes/Report/input_xml.xml
See the below thread also
Upload XML to internal table and vice versa in SAP 4.6C
Hope it will solve your problem..
Thanks & Regards

FM to read XML files from Application server in ECC5.0

Hi All,
We need to pick up an XML file from Application server/FTP server. The requirement is to parse the XML file and process it to create material master. SAP provides standard function modules to read XML files.
Now we need to read the XML file contents of MM01 and upload into SAP Data Base through BAPI
I need to know about the Function modules to read XML files from Application Server and also about the FM's that will update the Date base tables with the data obtained form XML files.
Regards
Prathima

For creating the material master look at BAPI_STANDARDMATERIAL_CREATE.

Is there any way to read XML directly from a Web Page ??

i have a url, which on sending request, shows XML in browser.
Now i need to read this XML in browser and then manipulate it according to my need and display it on another page.
actually the process is. :
1) i have to first retrieve an xml from other site. (XML will only be shown in browser)
2.)then i have to read the Xml and show it in according to my requirements.
Is there any way to read XML directly from a Web Page ??
is their logic to accomplish this.
e.g in Servlet i can do somewhat like this :
String wholeXml=Somemethod(url);
Please Advice

the average Java XML parser will accept an InputStream, so just open an URLConnection to the webpage, get the inputstream from it and feed that inputstream to the XML parser. If the URL has valid XML data, it will get parsed without problems.

Reading XML file from application server and put into internal table-4.6C

Dear All,
Is there any way of reading XML file from application server to SAP? I am using 4.6C. Function module SCMS_STRING_TO_XSTRING function module is not available. Please suggest.
Thanks and regards,
Atanu

Hi Atanu!
Simply use the XSLT transformation 'ID'.
FIELD-SYMBOLS <ls_result> TYPE ANY.
CREATE DATA lref_data TYPE (your_structure).
ASSIGN lref_data->* TO <ls_result>.
CALL TRANSFORMATION id
SOURCE XML xmlstr
RESULT result = <ls_result>.
"xmlstr" contains your XML file. Just read it into it via standard I/O operations. "<ls_result>" will contain your DDIC formatted content.
Best regards

Reading XML Data from ABAP Program?

Hi,
How do I read XML Data from an ABAP Program? For example if I have the below basic XML Code-
<xml>
<Name> Thiru </Name>
<Age> 24 </Age>
<City> chennai </Chennai>
</xml>
How do i read the data within the Name,Age, and City tags into variables in the ABAP Program?

if you decide to do in XSLT, I have a sample list here:
XML file like this:
<?xml version="1.0" encoding="UTF-16"?>
<F>
<P1>
<t_1>value1</t_1>
<t_2>testvalue</t_2>
</P1>
<P2>
</P2>
</F>
XSLT file like this:
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:sapxsl="http://www.sap.com/sapxsl" version="1.0">
<xsl:strip-space elements="*"/>
<xsl:template match="F">
<asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0">
<asx:values>
<DOCUMENT>

<T_1><xsl:value-of select="t_1"/></T_1>
<T_2><xsl:value-of select="t_2"/></T_2>
</ENTRY>
</xsl:template>
</xsl:transform>
ABAP program like this:

END OF wa_upload,
itab_upload LIKE TABLE OF wa_upload,
BEGIN OF wa_document,

I don't think you understand: I want to open Dreamweaver and build a brand new site, then when I am done I want to host the dreamweaver site on the Business Catalyst platform. I dont want to use anything in BC to build the site, I just want to use the hosting platform. I do not want to import a BC site into dreamweaver or anything like that. I just want to use BC the same way I would use godaddy, or uhost or any other hosting provider. Based on your response you said that "of course its possible to build a BC site in Dreamweaver" I dont want to build a BC site, I want to build a Dreamweaver site and host it on the BC platform. Like I said before it doesnt seem like this is possible. As of now we can only build a new site in MUSE and integrate it into BC without using a BC template. Can you understand what I am saying. I DONT WANT TO USE A BC TEMPLATE, I WANT NOTHING TO DO WITH BC WHILE I AM BUILDING THE SITE WITH DREAMWEAVER, JUST LIKE MUSE DOES.

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( ).

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/
