Help: How to parse XML string into Node Context

Hi Experts,
I am trying to work with a web dynpro for java application which calls a Web Service. I can call the web service successfully, however I have a problem on interpreting the response result into table. The response result is in (XML) string format, like this:
I followed this , but it resulted to an error:
com.sap.engine.lib.xml.parser.NestedSAXParserException: Fatal Error: com.sap.engine.lib.xml.parser.ParserException: Name expected: 0x20(:main:, row:158, col:59)(:main:, row=158, col=59) -> com.sap.engine.lib.xml.parser.ParserException: Name expected: 0x20(:main:, row:158, col:59)
do anyone of you had a similar experience and were able to resolve it, please post it here. it will be highly appreciated. thanks in advance.

Try this :
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new org.xml.sax.InputSource(new StringReader(strXml)));Hope this helps.

How to Parse a string into an XML DOM ?

Hi,
I want to parse a String into an XML DOM. Not able to locate any parser which supports that. Any pointers to this?

Download Xerces from xml.apache.org. Place the relevant JAR's on your classpath. Here is sample code to get a DOM document reference.

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 string fetched from the database

i want to parse the XML string which is fetched from the oracle database.
i have inserted the string in xml format in the database. The type of the field in which it is inserted is varchart2.
I am successfully getting it using jdbc, storing it in a String.
Now it is appended with xml version 1.0 and string is ready for parsing.
Now i am making following programming.
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = Builder.parse(xmlString);
Element root = doc.getDocumentElement();
NodeList node = root.getElementsByTagName("product");
But i am getting IOException at the statement
Document doc = Builder.parse(xmlString);
there fore i request u to kindly help me in solving this error.
-regards
pujan

DocumentBuilder does not have a method parse with xml string as aparameter. The string should be a xml document uri.
Convert xml string to StringReader.
parse(new InputSource(new StringReader(xmlString)));

Does anyone can help me to import XML string into a ORACLE database

Hi guys!
i have some problem that my friend wants me to convert XML string to Oracle relational database which means.
let's say, there is a table that a row has XML string.
so table has XML string with varchar type.
what my friend want me to do is, the string needs to be solved as a relational database.
like
A table has 'ID', 'data', 'result' rows
and Data column has XML string like <?xml version...............>
then wants to convert that data column's XML data into TABLE B with structure normally XML has.
i'm so confused and have no idea at all.. also i couldn't find any solution related to my stuff..
if someone knows how to solve the problem, just let us know
thx

The database is 10.2.0
What sort of example do u want me to give you..
i thought i give all information on the post..
i will explain it
let's say there are 3 columns ID,Name,Code
Id = normal integer
Name= varchar
Code= varchar
and i need to conver that XML in the Code column into relational databases
the code column has normal XML code which is starting from <?xml version.... and so on
so does it explain?
please help me!

How to parse xml string using JSTL

Suppose this is my string:-----
<books>
<book>
<title id=1>Book Title A</title>
<author>A. B. C.</author>
<price>17.95</price>
</book>
<book>
<title id=2>Book Title B</title>
<author>X. Y. Z.</author>
<price>24.99</price>
</book>
</books>
and I want to read title id = 1 then, how to parse it, I found tutorials regarding parsing simple xml document but how to parse attributes of a given XML

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)));

Helped, how to load xml data into database

Hi,
Given a DTD, can the XML SQL Utility generate
the database schema?
I currently have the dtd file to define
the data type and xml data and I am looking
for ways of how the XML/DTD can be loaded
into the oracle db.
Any suggestions/recommendations are
appreciated.
Thanks,
Judy

You could check out this web site:
http://www.rpbourret.com/xml/XMLAndDatabases.htm#software
where you can find a list of products that can translate a DTD to a relational schema. Also, there are several technical papers that discuss algorithms to carry out this translation. FYI, We have implemented a similar system,and testing it out.

How to Parse XML data directly from context variables in webdynpro

Hello,
   I have two requirements:
1) I have a context variable which has string value.
   I want to write the this value into a flat file.
   How do I do this in WebDynpro.
   Any sample code for this.
2) In Webdynpro, I want to parse and process the XML data directly from a string context variable which
   has the value in XML format.
   How do I achieve this. Any pointers or sample codes for this.
Thanks and Regards,
Anupama.

Anupama,
Here is some link which talks about unpacking xml and converting to HTML.
<a href="http://help.sap.com/saphelp_nw04/helpdata/en/eb/3dfb402eb5f76fe10000000a1550b0/content.htm">http://help.sap.com/saphelp_nw04/helpdata/en/eb/3dfb402eb5f76fe10000000a1550b0/content.htm</a>
I have done something like this in portal development and not in webdynpro.But in principle it should work very where.

How to get an xml string into a Document w/o escaping mark-up characters?

Hi,
I am using one of the latest xerces using Java. I am pretty sure I am using xerces-2.
I have an existing Document and I am trying to add more content to it. The new content itself is xml string. I am trying to insert this xml string into the document using document.createTextNode. I am able to insert, but somewhere it is escaping the mark-up characters (<,>,etc). When I convert the document into String, I can see, for example, <userData> instead of <userData>.
There is an alternative option to accomplish this by creating a new document with this xml string, get the root element, import this element into my document. Execution time for this procedure is very high - means, this is very bad in terms of time-wise performance.
Can any help on how to accomplish this (bringing an xml string into a document without escaping mark-up characters) in time-efficient way.

So you want to treat the contents of the string as XML rather than as text? Then you have to parse it.
Or if your reason for asking is just that you don't like the look of escaped text, then use a CDATA section to contain the text.

How to convert Java string into XML one?

With SAX I can parse an xml file, but I should create xml file by hands.
Ok, it's simple, but how to encode java string into XML constant
like "Hello & goodby" into "Hello & goodby" ?
Is there a standard method for such special xml characters?

If you are creating your XML "by hand" then just make sure your hands know that you have to do that. It isn't difficult to write a Java method to do it, if "by hand" means "in Java code". Otherwise your XML is not well-formed. And as far as I know there is no package that takes ill-formed XML and fixes it up.

REG: WRITE XML STRING INTO XML FILE

Hi All, I have a XML FILE on PC. I get a xml string from my server.
My Task: I want to append the xml string coming from the server into the existing xml file at a particular Node. Given below is my code :
String xmlString = baos.toString();
                  DocumentBuilder db4XMLString = docBuilderFactory.newDocumentBuilder();
                  InputSource inStream = new InputSource();
                  inStream.setCharacterStream(new StringReader(xmlString));
                  Document doc4XMLString = db4XMLString.parse(inStream);
                  Node root4XMLString = doc4XMLString.getElementsByTagName("epg").item(0);
                  doc.appendChild(doc.importNode(root4XMLString, true));
                  File file = new File(Constant.XMLFILEPATH);
                  Result result = new StreamResult(file.toURI().getPath());
                  Source source = new DOMSource(doc);
                  Transformer xformer = TransformerFactory.newInstance().newTransformer();
                  xformer.transform(source, result);But, wen i run my application I get following exception:
The markup in the document following the root element must be well-formed.
org.xml.sax.SAXParseException: The markup in the document following the root element must be well-formed.
at org.apache.xerces.parsers.DOMParser.parse(Unknown Source)
at org.apache.xerces.jaxp.DocumentBuilderImpl.parse(Unknown Source)
Is that my XML string is not well formed. Is it so then please let me how to convert my xml string into well formed XML data.
Please help me out.
Thanking You.

There are many reasons why xmlString could be not well formed. There is no magic recipe for making it well formed: just look at it and see why it is not parseable.
Note that this line:
String xmlString = baos.toString();can be problematic if you have non ASCII-7 characters in your XML document. baos could then contain a byte representation of these characters in one particular encoding, but, since you use the .toString() method that relies on the default encoding of your system, you can end up with a mismatch and garbage in your XML.

Convert XML string into DOM

Hi all,
I have a question here regarding converting XML string into a DOM document.
How can I do this in Java?
The Document.Parse() methods do not have one that takes in String as its parameter.
I'm not sure what is the best way to do this in Java.
Any help is greatly appreciated.
Thank you in advance.

return sb.toString();
}// END PRGM
Now , am not a very good Java DEv. and i need to find a soln. to this prob within 1 week.
The next step is to write the data to the DB.
Am sending an example of my file:
<Start>
<Machine>
<Hostname> IPCServer </Hostname>
<HostID> 80c04499 </HostID>
<MachineType> sun4u [ID 466748 kern.info] Sun Ultra 5/10 UPA/PCI (UltraSPARC-IIi 360MHz) </MachineType>

<EthernetAddress> 09:00:30:C1:34:90 </EthernetAddress>
<IPAddress> 149.51.23.140 </IPAddress>
</Machine>
</Start>
Note that i can have more than 1 machines (meaning that i have to loop thru the file to be able to write to the DB)
Cal u tellme what to do!
Even better- do u have a piece of code that will help me understand and implement the database writing portion?
I badly need help here.
THANX
