Extracting value from XML tags in Java

Hi all,
I need to extract the value from a string (XML Format). Eg. <Name>Ray</Name> and displaying Name: Ray
The string value is like any other String class object except that it is format with XML tags. I have quite a few examples that shows how a value can be read from a .xml file but none that describe how to get a value from a String object.
Thanks in advance.

                     DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
     DocumentBuilder parser = factory.newDocumentBuilder();
     Document document = parser.parse("Your XML Goes here ");

Regular expression to extract value from xml

Hi,
I need to extract the value of an XML tag.
<purchaseId>Best-200423</purchaseId>
The result of the expression should be: "Best-200423".
Something like this ([^\\<purchaseId\\>]*[^\\</purchaseId\\>]) does not work.
Does somebody has a soltuion?
I can't get it to work! I want to use the Java Regular Expression functionality.
Best wishes
Jochen

You got lucky, is all. Try changing "Best" to "pest" in your example and it won't work. The square brackets are spurious, and you want m.getGroup(1) to get the stuff that matches the () group.
Square brackes mean "match any of the characters in the brackets". [^ means "match any character not in this list").

Help needed in extracting values from XML

SAMPLE XML:
- <Form1>
- <Name>
<Ttl>MR</Ttl>
<Fore>ABC1</Fore>
<Sur>XYZ2</Sur>
</Name>
- <Address>
<Line>ADD_LINE_1</Line>
<Line>ADD_LINE_2</Line>
<PostCode>PST CDE</PostCode>
</Address>
<BirthDate>0001-01-01</BirthDate>
- <Details>
<TotalEarnings>1234567.00</TotalEarnings>
<TotalDeduction>12345.00</TotalDeduction>
</Details>
</Form1>
- <Form1>
- <Name>
<Ttl>MR</Ttl>
<Fore>ABC2</Fore>
<Sur>XYZ2</Sur>
</Name>
- <Address>
<Line>ADD_LINE_3</Line>
<Line>ADD_LINE_4</Line>
<PostCode>PST CDE</PostCode>
</Address>
<BirthDate>0002-02-02</BirthDate>
<Gender>female</Gender>
- <Details>
<TotalEarnings>12345.00</TotalEarnings>
<TotalDeduction>123.00</TotalDeduction>
</Details>
</Form1>
There can be any 'n' number of <Form1>'s in one XML.But I want to get only the details of the person whose TotalEarnings>1million. Details include
Name->Ttl,Fore,Sur
which in this case would be MR,ABC1,XYZ1
Address->Line,Line,Postcode
which in this case would be ADD_LINE_1,ADD_LINE_2,PST CDE
Birthdate
which in this case would be 0001-01-01
Gender
which in this case would be "null" as there is no Gender tag present
Details->TotalEarnings,TotalDeduction
which in this case would be 1234567.00,12345.00
The technique I was using is,
1. Convert to clob
2. User dbms_instr find the location of <Form1> in a loop
3. For every occurence of <Form1> I find <TotalEarnings> value and check if this is greater than 1 million.
4. If true, I use dbms_instr to get the values of all the tags inside <Form1>
5. The drawback of using dbms_instr is that it gets the value of first occurence of whatever sting we supply.In this case dbms_instr(xml,'<Gender>',position of Form1) will not return null whereas it will return "Female" from the next form. This is wrong as it doesnt belong to the person who earns more than a million.
Can anyone suggest a way to fetch the values that only belong to the form of the person who earns more than a million?

There can be any 'n' number of <Form1>'s in one
XML.Not if you want the XML to be valid there can't. You would need a root element around all the <Form1>'s to make it valid.

only belong to the form of the person who earns more
than a million?Why on earth are you using dbms_instr for this? Oracle has built in XML functionality for use against XMLTYPE data, such as the ExtractValue method and the use of XPATH expressions.
I'd suggest you start reading some of the manuals regarding XML functionality in Oracle rather than trying to manually parse it all.

The output should be:

531a8af7d9a9a5bb53b65a2b9a5356e5 0601-85-069-1 89.9
The count of rows and columns is variable.
I want to do this by using xmltype.extract but I found no way to create a loop over the content of the xml document.
Hopefully someone can help me!

Herbert

OK, then you should be able to use something like :

6 ligne(s) sélectionnée(s).You mentioned that the number of column(s) is not known in advance. That's gonna be a problem to present the data column-wise.
Version 11g has the PIVOT feature, but still you have to know how many columns there will be in the result set.
How are you going to use the data after extraction?
Maybe we could advise some other techniques more relevant for your requirement.

Hi,
You need to declare the namespace of each element used in the XPath expression, like this :
SQL> select extractvalue( XMLDATA
2                     , '/samp:Field1/UTI/U01'
3                     , 'xmlns:samp="http://www.oradev.com/chipsxml.xsd"' ) "XMLDATA"
4 from chipsxmltable1 x
5 ;
XMLDATA
No
SQL> select extract( XMLDATA
2                , '/samp:Field1/UTI'
3                , 'xmlns:samp="http://www.oradev.com/chipsxml.xsd"'
4                ).getstringval() "XMLDATA"
5 from chipsxmltable1 x
6 ;
XMLDATA
<UTI>
<U01>No</U01>
<U02>Y</U02>
<U03>Y</U03>
<U03a>Y</U03a>
<U03b>Y</U03b>
<U03c>Y</U03c>
<U04>Y</U04>
<U05>Y</U05>
</UTI>
Please see EXTRACT and EXTRACTVALUE documentation :

http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/functions052.htm#SQLRF06173
BTW, "XMLDATA" is a pseudo-column used by Oracle. I don't know if it'll ever cause any conflict but maybe you should rename your column.

Extracting data from a tag of xml file which is(xml) in a Field of Csv.

We have a xlm script which is stored in the clob column of the csv file. we have to extract one value from the <tag> and reject remaining data.
Sample:-
<ROW>
<ID>100</ID>
<ORDER_DATE>2000.12.20</ORDER_DATE>
<SHIPTO_NAME>Adrian Howard</SHIPTO_NAME>
<SHIPTO_STREET>500 Marine World Parkway</SHIPTO_STREET>
<SHIPTO_CITY>Redwood City</SHIPTO_CITY>
<SHIPTO_STATE>CA</SHIPTO_STATE>
<SHIPTO_ZIP>94065</SHIPTO_ZIP>
</ROW>
Required Output:-
We have to extract the "500 Marine World Parkway"
from tag <SHIPTO_STREET>
and the above sample xml file is in one of the column which is clob datatype
Any idea How to perform the above activity in PL/SQL ?

As BP suggested you can use an XPATH query to extract that information from your XML. However it depends a bit on your XML data.
Here are two examples:
one row XML
select extractvalue(xmltype('<ROW>
<ID>100</ID>
<ORDER_DATE>2000.12.20</ORDER_DATE>
<SHIPTO_NAME>Adrian Howard</SHIPTO_NAME>
<SHIPTO_STREET>500 Marine World Parkway</SHIPTO_STREET>
<SHIPTO_CITY>Redwood City</SHIPTO_CITY>
<SHIPTO_STATE>CA</SHIPTO_STATE>
<SHIPTO_ZIP>94065</SHIPTO_ZIP>
</ROW>')
,'//SHIPTO_STREET/text()') as result
from dual;
RESULT
500 Marine World Parkway
multi rows XML
select extractvalue(column_value,'SHIPTO_STREET/text()') as result
from table(xmlsequence(extract(xmltype('<ROWS>
<ROW>
<ID>100</ID>

Extracting data from XML

Im fairly new to XML & web services so bear with me please.
Im trying to extract data from XML documents where the structure/element names are unknown.
The condition for extracting data is if keyword matches some data content.
Im using Java and the DOM API with xcerces and I've managed to parse the XML file, what I need to do next is to traverse the data content checking against keywords and if a keyword matches then to strip the tags and save the data locally ?
Ive trawled through all the documentaion but as theres so many different methods Im somewhat unsuare which is the best way to proceed.
thanks

tough question, i would suggest looking at jdom as solution for you, because it is a relatively simple one to use for searching through a dom. aside from that, its probably up to you what sort of logic you want to use.

How to get string value from xml in JSF??

In JSF How to get string value from xml, .ini and properties file. I want to get string value from xml or text to JSF

Just use the appropriate API's for that. There are enough API's out which can read/parse/write XML, ini and properties files. E.g. JAXP or DOM4J for xml files, INI4J for ini files and Sun's own java.util.Properties for propertiesfiles.
JSF supports properties files as message bundle and resource bundle so that you can use them for error messages and/or localization.

How to retrieve value from xml file

hi shanu,
the pbm is solved, now i m able to access XXX no. in action class & i m able to validate it. The only thing which i want to know is it ok to declare static ArrayList as i have done in this code. i mean will it affect the performance or functionality of the system.
pls have a look at the following code snippet.
public class XMLValidator {
static ArrayList strXXX = new ArrayList();
public void validate(){
factory.setValidating(true);
parser = factory.newSAXParser();
//all factory code is here only
parser.parse(xmlURI, new XMLErrorHandler());
public void setXXX(String pstrXXX){
strUpn.add(pstrXXX);
public ArrayList getXXX(){
return strXXX;
class XMLErrorHandler extends DefaultHandler {
String tagName = "";
String tagValue = "";
String applicationRefNo = "";
String XXXValue ="";
String XXXNo = "";
XMLValidator objXmlValidator = new XMLValidator();
public void startElement(String uri, String name, String qName, Attributes atts) {
tagName = qName;
public void characters(char ch[], int start, int length) {
if ("Reference".equals(tagName)) {
tagValue = new String(ch, start, length).trim();
if (tagValue.length() > 0) {
RefNo = new String(ch, start, length);
if ("XXX".equals(tagName)) {
XXXValue = new String(ch, start, length).trim();
if (XXXValue.length() > 0) {
XXXNo = new String(ch, start, length);
public void endElement(String uri, String localName, String qName) throws SAXException {
if(qName.equalsIgnoreCase("XXX")) {
objXmlValidator.setXXX(XXXNo);
thnx & Regards,
