How to parse xml in sap abap

Hello,
Can anyone help me to know how to parse xml in sap abap.
I have a xml file which i want to parse and store it in internal table.
<?xml version="1.0" encoding="UTF-8"?>##<data><name>menaka<name></data>
Regards,
Menaka.H.B

Hello,
For how to get the node name, you have to refer to this :
[https://wiki.sdn.sap.com/wiki/display/ABAP/Upload%20XML%20file%20to%20internal%20table|https://wiki.sdn.sap.com/wiki/display/ABAP/Upload%20XML%20file%20to%20internal%20table]
Check the code after:
WHEN if_ixml_node=>co_node_element
It tells you how to get the node name.

How to parse XML for internal table

hi guys, I would like to know how to parse xml for an internal table. I explain myself.
Let's say you have a purchase order form where you have header data & items data. In my interactive form, the user can change the purchase order quantity at the item level. When I received back the pdf completed by mail, I need to parse the xml and get the po qty that has been entered.
This is how I do to get header data from my form
lr_ixml_node = lr_ixml_document->find_from_name( name = ''EBELN ).
lv_ebeln = lr_ixml_node->get_value( ).
How do we do to get the table body??
Should I used the same method (find_from_name) and passing the depth parameter inside a do/enddo?
thanks
Alexandre Giguere

Alexandre,
Here is an example. Suppose your internal table is called 'ITEMS'.
lr_node = lr_document->find_from_name('ITEMS').
lv_num_of_children = lr_node->num_children( ).
lr_nodechild = lr_node->get_first_child( ).
do lv_num_of_children times.
    lv_num_of_attributes = lr_nodechild->num_children( ).
    lr_childchild = lr_nodechild->get_first_child( ).
   do lv_num_of_attributes times.
      lv_value = lr_childchild->get_value( ).
      case sy-index.
         when 1.
           wa_item-field1 = lv_value
         when 2.
           wa_item-field2 = lv_value.
      endcase.
      lr_childchild = lr_childchild->get_next( ).
   enddo.
   append wa_item to lt_item.
   lr_nodechild = lr_nodechild->get_next( ).
enddo.

How to parse XML against XSD,DTD, etc.. locally (no internet connection) ?

i've searched on how to parse xml against xsd,dtd,etc.. without the needs of internet connection..
but unfortunately, only the xsd file can be set locally and still there needs the internet connection for the other features, properties.
XML: GML file input from gui

Thanks a lot Sir DrClap..
I tried to use and implement the org.w3c.dom.ls.LSResourceResolver Interface which is based on the SAX2 EntityResolver.
please give comments the way I implement it. Here's the code:
LSResourceResolver Implementation
import org.w3c.dom.ls.LSInput;
import org.w3c.dom.ls.LSResourceResolver;
import abc.xml.XsdConstant.Path.DTD;
import abc.xml.XsdConstant.Path.XSD;
public class LSResourceResolverImpl implements LSResourceResolver {
     public LSResourceResolverImpl() {
      * {@inheritDoc}
     @Override
     public LSInput resolveResource(String type, String namespaceURI, String publicId, String systemId, String baseURI) {
          ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
          LSInput input = new LSInputImpl(publicId, systemId, baseURI);
          if ("http://www.w3.org/2001/xml.xsd".equals(systemId)) {
               input.setByteStream(classLoader.getResourceAsStream(XSD.XML));
          } else if (XsdConstant.PUBLIC_ID_XMLSCHEMA.equals(publicId)) {
               input.setByteStream(classLoader.getResourceAsStream(DTD.XML_SCHEMA));
          } else if (XsdConstant.PUBLIC_ID_DATATYPES.equals(publicId)) {
               input.setByteStream(classLoader.getResourceAsStream(DTD.DATATYPES));
          return input;
}I also implement org.w3c.dom.ls.LSInput
import java.io.InputStream;
import java.io.Reader;
import org.w3c.dom.ls.LSInput;
public class LSInputImpl implements LSInput {
     private String publicId;
     private String systemId;
     private String baseURI;
     private InputStream byteStream;
     private String stringData;
     public LSInputImpl(String publicId, String systemId, String baseURI) {
          super();
          this.publicId = publicId;
          this.systemId = systemId;
          this.baseURI = baseURI;
     //getters & setters
}Then, here's the usage/application:
I create XMLChecker class (SchemaFactory implementation is Xerces)

          SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);

How to parse xml string

Hi! I'm having problems parsing an xml string. I've done DOM and SAX parsing before. But both of them either parse a file or data from an input source. I don't think they handle strings. I also don't want to write the string into a file just so I can use DOM or SAX.
I'm looking for something where I could simply do:
Document doc = documentBuilder.parse( myXMLString );
So the heirarchy is automatically established for me. Then I could just do
Element elem = doc.getElement();
String name = elem.getTagName();
These aren't the only methods I would want to use. Again, my main problem is how to parse xml if it is stored in a string, not a file, nor comming from a stream.
thanks!

But both of them either parse a file or data from an input source. I don't think they handle strings.An InputSource can be constructed with a Reader as input. One useful subclass of Reader is StringReader, so you'd use something likeDocument doc = documentBuilder.parse(new InputSource(new StringReader(myXMLString)));

How to parse xml and import to execel

pls let me know how to parse XML file and import all data to execel sheet.

Hi Mandya,
This is outside of the normal use case for TestStand. It would be best to use a code module (developed in LabVIEW, C, or any other language) to accomlish this and then call it from a step in TestStand. You can find examples on ActiveX here:

Parsing XML Files to ABAP

Hello All,
There is a requirement for parsing of XML files to ABAP.
1.How do we pick an XML file from Application server and also from FTP server?
2.After picking the XML file how to parse that XML file to process it to create material master?

Hi,
Ur scenario is File to R/3
For creating material master ..i guess there is IDoc named MATMAS.
U can make use of it and execute File to IDoc Scenario.
link for File to IDoc--
https://www.sdn.sap.com/irj/scn/wiki?path=/display/xi/fileToIDOC&
U need to pick XML file from FTP server...No need to parse XML file...just create data type which represents ur xml file structure and map it to IDoc fields.
regards,
Manisha

How to parse XML files from normal FTP Servers?

I want to parse xml files from a normal FTP Servers , NOT the sap application severs itself. How can i do that?
I know how to use the SAPFTP getting and putting files ,but I don't want to download and then parse it.
Who knows how to parse it directly? I Just need to read the contents into a database.
Thanks.

Parse XML streams via ABAP program or class

Hi all,
because of a new requirement we would like to create characteristics from a XML file by using the following structure.
xmlns:gdt="http://sap.com/xi/SAPGlobal/Global" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
We do not use SAP XI but I would like to parse the XML stream from a file in order to have the information available in a ABAP program. For this reason I'm looking for a standard SAP ABAP program or class to read and parse such a XML file.
I would appreciate if somebody have more details on this topic.

How to parse XML to Java object... please help really stuck

Thank you for reading this email...
If I have a **DTD** like:
<!ELEMENT person (name, age)>
<!ATTLIST person
     id ID #REQUIRED
>
<!ELEMENT name ((family, given) | (given, family))>
<!ELEMENT age (#PCDATA)>
<!ELEMENT family (#PCDATA)>
<!ELEMENT given (#PCDATA)>
the **XML** like:
<person id="a1">
<name>
     <family> Yoshi </family>
     <given> Samurai </given>
</name>
<age> 21 </age>
</person>
**** Could you help me to write a simple parser to parse my DTD and XML to Java object, and how can I use those objects... sorry if the problem is too basic, I am a beginner and very stuck... I am very confuse with SAXParserFactory, SAXParser, ParserAdapter and DOM has its own Factory and Parser, so confuse...
Thank you for your help, Yo

Hi, Yo,
Thank you very much for your help. And I Wish you are there...I'm. And I plan to stay - It's sunny and warm here in Honolulu and the waves are up :)
A bit more question for dear people:
In the notes, it's mainly focus on JAXB,
1. Is that mean JAXB is most popular parser for
parsing XML into Java object? With me, definitely. There are essentially 3 technologies that allow you to parse XML documents:
1) "Callbacks" (e.g. SAX in JAXP): You write a class that overrides 3 methods that will be called i) whenever the parser encounters a start tag, ii) an end tag, or iii) PCDATA. Drawback: You have to figure out where the heck in the document hierarchy you are when such a callback happens, because the same method is called on EACH start tag and similarly for the end tag and the PCDATA. You have to create the objects and put them into your own data structure - it's very tedious, but you have complete control. (Well, more or less.)
2) "Tree" (e.g. DOM in JAXP, or it's better cousin JDOM): You call a parser that in one swoop creates an entire hierarchy that corresponds to the XML document. You don't get called on each tag as with SAX, you just get the root of the resulting tree. Drawback: All the nodes in the tree have the same type! You probably want to know which tags are in the document, don't you? Well, you'll have to traverse the tree and ask each node: What tag do you represent? And what are your attributes? (You get only strings in response even though your attributes often represent numbers.) Unless you want to display the tree - that's a nice application, you can do it as a tree model for JTree -, or otherwise don't care about the individual tags, DOM is not of much help, because you have to keep track where in the tree you are while you traverse it.
3) Enter JAXB (or Castor, or ...): You give it a grammar of the XML documents you want to parse, or "unmarshall" as the fashion dictates to call it. (Actually the name isn't that bad, because "parsing" focuses on the input text while "unmarshalling" focuses on the objects you get, even though I'd reason that it should be marshalling that converts into objects and unmarshalling that converts objects to something else, and not vice versa but that's just my opinion.) The JAXB compiler creates a bunch of source files each with one (or now more) class(es) (and now interfaces) that correspond to the elements/tags of your grammar. (Now "compiler" is a true jevel of a misnomer, try to explain to students that after they run the "compiler", they still need to compile the sources the "compiler" generated with the real Java compiler!). Ok, you've got these sources compiled. Now you call one single method, unmarshall() and as a result you get the root node of the hierarchy that corresponds to the XML document. Sounds like DOM, but it's much better - the objects in the resulting tree don't have all the same type, but their type depends on the tag they represent. E.g if there is the tag <ball-game> then there will be an object of type myPackage.BallGame in your data structure. It gets better, if there is <score> inside <ball-game> and you have an object ballGame (of type BallGame) that you can simply call ballGame.getScore() and you get an object of type myPackage.Score. In other words, the child tags become properties of the parent object. Even better, the attributes become properties, too, so as far as your program is concerned there is no difference whether the property value was originally a tag or an attribute. On top of that, you can tell in your schema that the property has an int value - or another primitive type (that's like that in 1.0, in the early release you'll have to do it in the additional xjs file). So this is a very natural way to explore the data structure of the XML document. Of course there are drawbacks, but they are minor: daunting complexity and, as a consequence, very steep learning curve, documentation that leaves much to reader's phantasy - read trial and error - (the user's guide is too simplicistic and the examples too primitive, e.g. they don't even tell you how to make a schema where a tag has only attributes) and reference manual that has ~200 pages full of technicalities and you have to look with magnifying glas for the really usefull stuff, huge number of generated classes, some of which you may not need at all (and in 1.0 the number has doubled because each class has an accompanying interface), etc., etc. But overall, all that pales compared to the drastically improved efficiency of the programmer's efforts, i.e. your time. The time you'll spend learning the intricacies is well spent, you'll learn it once and then it will shorten your programming time all the time you use it. It's like C and Java, Java is order of magnitude more complex, but you'd probably never be sorry you gave up C.
Of course the above essay leaves out lots and lots of detail, but I think that it touches the most important points.
A word about JAXB 1.0 vs. Early Release (EA) version. If you have time, definitively learn 1.0, they are quite different and the main advantage is that the schema combines all the info that you had to formulate in the DTD and in the xjs file when using the EA version. I suggested EA was because you had a DTD already, but in retrospect, you better start from scratch with 1.0. The concepts in 1.0 are here to stay and once your surmounted the learning curve, you'll be glad that you don't have to switch concepts.
When parser job is done,
what kind of Java Object we will get? (String,
InputStream or ...)See above, typically it's an object whose type is defined as a class (and interface in 1.0) within the sources that JABX generates. Or it can be a String or one of the primitive types - you tell the "compiler" in the schema (xjs file in EA) what you want!
2. If we want to use JAXB, we have to contain a
XJS-file? Something like:In EA, yes. In 1.0 no - it's all in the schema.
I am very new to XML, is there any simpler way to get
around them? It has already take me 4 days to find a
simple parser which give it XML and DTD, then return
to me Java objects ... I mean if that kind of parser
exists....It'll take you probably magnitude longer that that to get really familiar with JAXB, but believe me it's worth it. You'll save countless days if not weeks once you'll start developing serious software with it. How long did it take you to learn Java and it's main APIs? You'll either invest the time learning how to use the software others have written, or you invest it writing it yourself. I'll take the former any time. But it's only my opinion...

How to parse xml in jsp

hei evryone!!!
I'm a newbie in java, i just wanna know how to parse an xml file in JSP wherein i could remove nodes / modify certain nodes on the xml.
Any suggestions / codes/ ideas would be much appreciated

On my jsp page the default screen would be the list of traders. The user of the said application has the option to make some changes on the list either, add more trader/s on the list , remove specified trader/s on the list or edit certain trader/s. Furthermore, the user can also cancel the changes he made by clicking the cancel button or commit the modification he made by clicking the save button. When the application altered something, the changes must be reflected on the front end right away, but not on the database yet. In doing so, I intend to have two xml files , (1) the original xml file that is send to a CmsServlet (the servlet code that does the database commit) and (2) the temporary xml file that the page loads, which is initially just a copy of the original xml file. So whenever changes made at the frontend the temporary file is also altered, and when the save button is clicked, the temporary file is copied to original xml file to send the changes on the CmsServlet. But when the application user withdraws the changes he made at the frontend by clicking the cancel button , the original xml file is then copied to temporary xml file to reload the page.
The access/modification on the temporary xml file is done in default.jsp.

How to parse XML file with namesapce?

Hi,
   I am trying to parse an xml file having namespace. But no data is returned.
Sample Code:
public class XMLFileLoader
var xml:XML = new XML();
var myXML:XML = new XML();
var XML_URL:String = "file:///C:/Documents and Settings/Administrator/Desktop/MyData.xml";
var myLoader:URLLoader = null;
public function XMLFileLoader()
var myXMLURL:URLRequest = new URLRequest(XML_URL);
myLoader= new URLLoader(myXMLURL);
myLoader.addEventListener(Event.COMPLETE,download);
public function download(event:Event):void
myXML = XML(myLoader.data);
var ns:Namespace=myXML.namespace("xsi");
for(var prop:String in myXML)
     trace(prop);
//Alert.show(myXML..Parameters);
//trace("Data loadedww."+myXML.toString());
//Alert.show(myXML.DocumentInfo.attributes()+"test","Message");
The XML Contains the following format.
<Network xmlns="http://www.test.com/2005/test/omc/conf"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://www.test.com/2005/test/omc/conf/TestConfigurationEdition3proposal4.xsd">
    <TestDomain>
      <WAC>
        
        <Parameters ParameterName="ne_release" OutageType="None"
                    accessRight="CreateOnly" isMandatory="true"
                    Planned="false"
                    Reference="true" Working="true">
          <DataType>
            <StringType/>
          </DataType>
          <GUIInfo graphicalName="Release"
                   tabName="All"
                   description="Describes the release version of the managed object"/>
        </Parameters>
</TestDomain>
</Network>

i have exactly the same problem with KXml2, but using a j2me-polish netbeans project.
i've tried to work around with similar ways like you, but none of them worked. now i've spent 3 days for solving this problem, i'm a bit disappointed :( what is wrong with setting the downloaded kxml2 jar path in libraries&resources?
