Parsing a single string

I apologize if the question is trivial, but I have been working on it for a while.
I would like to send a single string containing one XML element to the parser. I can't figure out a way to do it.
Of course, I can easily parse files, but for communication purposes, I need a way to parse just single elements, that are stored in separate strings, and find out their contents.
Thank you,
Sol

Can't your parser accept a Reader as input? Check its API documentation to find that out. If it can, then "whatever.parse(new StringReader(yourXmlString))" is what you want.

Using String manipulation is likely to be faster than using a DOM (assuming you had valid XML) however if performance were an issue you would use JDBC to access the database.What will happen, if OP has large number of nodes in the string? Will String manipulation be the faster one? String manipulation will be faster only if the string has one or two nodes. Otherwise it will be complicated.Direct String manipulation will always be faster. This is because you can make assumptions a full DOM will not make (as it needs to be able to read any type of XML document)
For this reason its best avoided unless you really need the speed as any subtle change in the XML could break a simplified parser.

Is there a way in Oracle to return multiple rows as a single string?

Hi gurus,
I just got help from your guys fixing my dynamic sql problem. What I am doing in that function is to return a single string from multiple rows and I use it in the select statement. It works fine once the problem was solved. But is there any way in Oracle to do this in the select statement only? I have a table that stores incidents (incident_id is the PK) and another table that stores the people that are involved in an incident.
Incident_table
(incident_id number PK);
Incident_people_table
(incident_id number PK/FK,
person_id number PK);
Now in a report, I need to return the multiple rows of the Incident_People_table as a single string separated by a comma, for example, 'Ben, John, Mark'. I asked the SQL Server DBA about this and he told me he can do that in SQL Server by using a variable in the sql statement and SQL Server will auomatically iterate the rows and concatenate the result (I have not seen his actual work). Is there a similar way in Oracle? I have seen some examples here for some similar requests using the sys_connect_by_path, but I wonder if it is feasible in a report sql that is already rather complex. Or should I just stick to my simpler funcion?
Thanks.

Hi,
May be, this example will help you.

Parsing an xml string into id-value pair format

Hi,
I am new in oracle BPEL.
My requirement is that I need to parse an xml string containing tag name and coressponding value into an 'id -value' pair.
For example-
The input xml format is -
<employee>
<empid>12345</empid>
<name>xyz</name>
<city>London</city>
</employee>
The required xml format is-
<employee>
<item id="empid" value="12345"/>
<item id="name" value="xyz"/>
<item id="city" value="London"/>
</employee>
Please let me know if there is a work-around for this.
Thanks

Something like this (have not tested):
<xsl:for-each select="//employee">
<employee>
<xsl:for-each select="./*">
<item>
<xsl:attribute name="id">
<xsl:value-of select="name()"/>
</xsl:attribute>
<xsl:attribute name="value">
<xsl:value-of select="text()"/>
</xsl:attribute>
</item>
</xsl:for-each>
</employee>
</xsl:for-each>

Parsing an XML string

How would I get the Oracle XML Parser to parse an XML string?
The example ("DOMSample") only demonstrates how to parse an XML
file -- I would like to do something of the form...
parser.parse("<test>testing</test>");
On a related note, whilst the PL/SQL utilities are helpful, I
would like to see more in the way of documentation and examples
for the Parser itself, showing more examples of DOM API calls and
perhaps a complete worked example (including a DTD).
Keep up the good work!
Many thanks,

With the latest version, 1.0.0.1, now available, you can use the
InputStream and InputSource methods. Please see the doc for
details.

SaxParser error parsing xml encoded string

I'm trying to parse an XML string with Java's SaxParser. The program
fails at the end of an element or at the beginning of a new element.
Is my XML string okay?
<?xml version="1.0" encoding="utf-8"
?><DTYPE>OVL</DTYPE><DTYPE>IMG</DTYPE>. . .
If fails after </DTYPE> and before the next <DTYPE>
The Sax Parser works fine on files.
Here is the code I use to send the string to the parser :
// Parse the input
SAXParser saxParser = factory.newSAXParser();
InputStream is = new ByteArrayInputStream(stringToParse.getBytes());
saxParser.parse( is, handler );
Here is the error message I get :

<?xml version="1.0" encoding="utf-8" ?><DTYPE>IMG</DTYPE><DTYPE>REF</DTYPE>Above is a short XML string that causes the problem.
It's all one line.
I also tried adding System.getProperty("line.separator") add the
end of each tag so I get :
<?xml version="1.0" encoding="utf-8" ?>
<DTYPE>IMG</DTYPE>
<DTYPE>REF</DTYPE>But same error. It still crashes after the first <DTYPE></DTYPE> tag.
Any help greatly appreciated!

How to Parse an XML string

I need some help to parse an XML String instead of an XML file. The string can be like.
String myRecords =
"<data>"+
" <employee>"+
" <name>John</name>"+
" <Designation>Manager</Designation>"+
" </employee>"+
" <employee>"+
" <name>Sara</name>"+
" <Designation>Clerk</Designation>"+
" </employee>"+
"<data>"+

I tried it in a servlet, it and it worked. The entire code is long. But here it is most of it:
assuming that x is a string and has the xml of
<?xml version="1.0" ?>
- <company>
- <employee>
<firstname>Tom</firstname>
<lastname>Cat</lastname>
</employee>
- <employee>
<firstname>Paul</firstname>
<lastname>Enderson</lastname>
</employee>
- <employee>
<firstname>George</firstname>
<lastname>Jungle</lastname>
</employee>
</company>
=========================
try {
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
DocumentBuilder db = factory.newDocumentBuilder();
InputSource inStream = new InputSource();
inStream.setCharacterStream(new StringReader(*x*));
Document doc = db.parse(inStream);
doc.getDocumentElement().normalize();
out.println("Root element " + doc.getDocumentElement().getNodeName() + " ");
NodeList nodeLst = doc.getElementsByTagName("employee");
out.println("Information of all employees ");
for (int s = 0; s < nodeLst.getLength(); s++) {
Node fstNode = nodeLst.item(s);
if (fstNode.getNodeType() == Node.ELEMENT_NODE) {
Element fstElmnt = (Element) fstNode;
NodeList fstNmElmntLst = fstElmnt.getElementsByTagName("firstname");
Element fstNmElmnt = (Element) fstNmElmntLst.item(0);
NodeList fstNm = fstNmElmnt.getChildNodes();
out.println("First Name : " + ((Node) fstNm.item(0)).getNodeValue() + " ");
NodeList lstNmElmntLst = fstElmnt.getElementsByTagName("lastname");
Element lstNmElmnt = (Element) lstNmElmntLst.item(0);
NodeList lstNm = lstNmElmnt.getChildNodes();
out.println("Last Name : " + ((Node) lstNm.item(0)).getNodeValue() + " ");

Problem in parsing a xml string using dom parser

i want to parse a Xml String using a Dom parser......the parse function in dom parser takes only input stream as argument.......so i made the code as
InputStream inputstream = new StringBufferInputStream(XmlData) ;
InputSource inputSource = new InputSource(inputstream );
but saxexception is coming and also warning called
"java.io.StringBufferInputStream in java.io has been deprecated"
please help me.........

i want to parse a Xml String using a Dom
parser......the parse function in dom parser takes
only input stream as argument.......This is not true of the DOM parser in Java 1.4. So you might want to get rid of your old parser and replace it by something more current. Or perhaps you are using 1.4 and you just didn't read all of the API docs.

Concate mutiple input in to Single String.

Hi ,
I need one help .
I want to contcat the one of the IDOC fields occurance in a single string. Please let me know how to user.
For Ex. I am mapping one field of Idoc ex TDLINE --> Extrinsic (0.. Unbounded)in the output side.
In the Input side the TDLINE fields appears multiple time. in the current mapping I have one to one mapping between TDLINE and Extrinsic fields. So it creates the same number of Extrinsic fields as I have TDLINE fields at input side.
What I want to do , I want to create a single Extrinisc fields at output side for all the TDLINE fields.
For Ex. At particaular segment I have 10 fields for TDLine then all should come as Single string at out put side.
Note . No of Occurance of TD line is 0.. unbounded).
Please give ur suggestions for the same.

Single string tag expanded into 100 plc register values

I found a way to read 100 registers of plc data with a single string tag, if you can guarantee that none of the plc registers are zero. A register value of zero acts like a Null ascii terminator and truncates the string. Define the string tag as 200 bytes and uncheck the text data only box. Use the code in the attached picture to convert the string bytes back into decimal register values.
