Extract xml tags in java

ho can I extract the xml tags and its value in a java programs

Check out the API docs for javax.xml and javax.xml.parser. If you want to parse via DOM (IMHO, the easiest way to learn), then download Xerces from xml.apache.org. There are numerous FAQ's and HOW-TO's on that site.

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 ");

Document contains too many nodes error when extracting xml tag name

I Have a large xml file in which the tag contains ~: as the value.
Now I am trying to extract all the tags which have ~: as the value and store that column using the following query and insert into a table.
insert into space_md select distinct xmltype(extract(value(x), '/').getstringval()).getrootelement() COLUMN_NAME
from gt_xmltype_tab gt, TABLE(XMLSequence(extract(gt.xmlfile1, '/ROWSET/ROW/*'))) x
where instr(extract(value(x),'/').getstringval(),'~:') > 1;
The xml file was generated using dbms_xmlgen.getxml. Table has 48 columns and around 4000 rows.
My above insert query gave me an error of 31186 too many nodes error.
I am using oracle version 10.2.0.3.
Following are the set of commands I ran....
SQL> insert into gt_xmltype_tab(xmlfile1)
values(XMLType(bfilename('BKUP_RES','QC.xml'),nls_charset_id('AL32UTF8'))); 2
1 row created.
SQL> SQL>
SQL> insert into restore_space_metadata select distinct 'QC', xmltype(extract(value(x), '/').getstringval()).getrootelement() COLUMN_NAME
2 from gt_xmltype_tab gt, TABLE(XMLSequence(extract(gt.xmlfile1, '/ROWSET/ROW/*'))) x
3 where instr(extract(value(x),'/').getstringval(),'~:') > 1;
insert into restore_space_metadata select distinct 'QC', xmltype(extract(value(x), '/').getstringval()).getrootelement() COLUMN_NAME
ERROR at line 1:
ORA-31186: Document contains too many nodes
Is there a better way of extracting the xml tag element name based on the xmltag content?
There is one other table which has 172 columns but only 100 rows so it doesnt create any problem on that table.
But this QC table has less columns but many many rows...
Any suggestions

There is a requiremnent of taking centain type of data backup and restore it.
It was implemented on flat file approach which was giving errors.
So it was implemented using XML approach.
Read data, store in xml file and read from xml file and load it into table.
Further, found that dbms_xmlstore is not able to handle tag only with whitespace
and tried to use the loading xml file into xmltype table column and extract data.
XMLTYPE column also has same problem of ignoring whitespace when used with extractvalue functions.
So for the workaround I update xmlfile having only one more more whitespace in the tag to have ~: character once.
After restoring data from xml to table I would run update qeury to update ~: to " ".
Now instead of running blind update for all the tables and all the columns from ~: to " " I thouhgt whyy not create a xml file of tag having ~:
along with its tablename.
and thats where I found the problem of too many nodes...
THe insert query you saw is populating table for table_name and column_name with tag having only ~: in it.
I hope this gives you the fair idea of stuff I am doing.

How to extract xml tag name contains dashes

Hi, How to parse XML file to extract root tag contains dashes in Flex,for example
XML Input is: <regular-body>Text of my post...</regular-body>
expected output is : regular-body
I appreciate any of your suggestions or inputs

Do you want to get the name of the XML ELEMENT regular-body, or the value in the XML file "Text of my post...".
If its the latter, then you could use the bracket/quote notation for extracting the value, like in the following example:
image = xmlWeather[0]..parameters["conditions-icon"]["icon-link"][idx]
I use this when parsing weather information from a 3rd party in which their XML is loaded with dashes.
If you are looking to get the actual element name, not sure how to do that. I would think that if you are using an XML file, you would have at least the high level element known.

Extracting XML tags and its values using ORACLE PL/SQL

I need help to create a procedure that receive a XML string and insert it into the table after parsing it.
If the XML has 10 tags then it should insert into the table 10 rows. Table will be having tag name and value. This will be plain XML tags without attributes in tags.

Hi,
I am able to retreive the values of the tags using extract function (example: lv_xml.EXTRACT ('/ROWSET/EMPLOYEE/EMPNO/text()').getstringval() ). But could you help me to find some way to extract the tags also since we have no idea what the tags are and how many tags are there, in advance.
Anybody's help will be a releif!
Thanks in advance,

How to create nested xml tags using java parser?

Hi,
I need to create a xml file containing following tags using java program-
<A attr1="abc">
<B attr2="xyz">
<C attr3="pqr"> </C>
</B>
</A>
Can anyone please let me know which parser should I use to create the above mentioned xml file?
If possible, please post a code snippet for the same.
Thanks in advance..

Well, you could start by doing it all the 'old fashioned' way; create a String object containing that text and then write it away to a file. Or you could take the time to look at the javadoc for all of the xml support that the Java language itself supplies - XMLReader/Writer for a start. After that put together some code that you think would do the job and ask for help on any specific problems you encounter.

Q: How to access and modify xml tags using Java

I have an xml based document that i need to access and change. For example, the code
<section id="section1">
<div>
<xforms:group id="id1">
<xforms:label id="label1">
<l style="font-size:16pt"> something </l>
</xforms:label>
</xforms:group>
</div>
</section>
Working with Java I need to access all the tags, select some of them that are relevant to the current device and remade the document. I thought I would read the file character by character identifying the different labels and building a tree, storing in the tree nodes the relevant information as some kind of attributes (for example, in the case of the <xforms:group id="id1"> I would name the node "xforms:group" and create an "id" attribute with value "id1"). I'm not sure if that is the most efficient way of accessing the problem (computational power might be an issue), and would appreciate some help on the subject.
Thanks,

this may help you..
this is a little util i made to help me read/write files.
using this, you are only one step away from your solutions, you only need to figure out the regex you need to run on the text of the file to make it become what you need it to become.
though if you use non-standard encoding, you might not want to use this code..

Search and Replace XML TAG using JAVA

Hi All,
I have an XML file, say RESULT.XML Which has about 30000 Lines (yes Thirty Thousand ). For some reason i need to replace an existing tag with a different tag(not the value inside the tag, But the tag itself) . I am facing a challenge. I will explain it as below.
I have a csv file which has 2 values as given below
<VALUE A> , <VALUE B>
where <VALUE A> is an existing node in the RESULT.XML and <VALUE B> is the node that should replace <VALUE A> in the RESULT.XML
i have 500 such entries in the file.
Now i need to write a program to read the csv file, Search <VALUE A> in the RESULT.XML and Replace it with <VALUE B> of the csv file.
please let me know how do i start with this.
I really want to fix this issue.
Existing Node = <Product ID="role (contact) 3" UserTypeID="Product Number">_
To be changed to = <Product ID= role (contact)3" UserTypeID="Product Number">_
please reply if you need any further information
Thanks in Advance
Manzoor

Sounds like a job for XSLT or Perl not Java though it can be done in Java. In Java I would initially try
1) Read the csv file using one of the many free CSV parsers and build a Map<String,String>.
2) Create a Rewriter using the map keys as targets and use the map values as replacements.
3) Read the XML file line by line and process each line with the Rewriter.
4) Save each line to an output file.
For a one-off task this would probably serve but it could prove very slow if you need to run this on a daily basis.

Unless you are using some special tag library or something, SQL is not, as far as I've ever seen, going to handle while loops within the statements. You want to create the table, then you have to create the CREATE statement string
String c = "CREATE TABLE [dbo].[tblNewTable] (";
for(int x = 0; x < vFieldFruitVector.size(); x++) {
c += vFieldFruitVector.get(x) + " char 50 COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL";
c += ")";
int res = stmt.executeUpdate(c);

How to comment the xml tags using java

Iam using a xml file i want to comment some of the tags in that file

And your quesion is? Did you parse it into a Document and do you want to write a changed version into another file?

Newbie trying to analyze code for xml tags

My problem is that I need to find what xml tags my java files contain. Is there a way to run a search and pull out all xml tags? Thank you.

you mean you have to find xml tags in .java file. you have to write a program that will read the contents of file and then check for any string that contains < and ends with >. U can use LineNumberReader class for reading a line. besides these u have to take care of comments.

Unknown xml tag extraction

I have an XML document with the following structure:
<foo>
     <foo id="F1">television</foo>
     <foo id="F2">car</foo>
</foo>
foo id can be none or up to 99. So I want to extract the tag "F1", "F2", etc. and its content when it shows up in a document to enter them in separate fields in a database. I have tried different codes but with no luck. These two are my latest methods but they don't work as expected. The second method gives an error message at the line "matcher = pattern.matcher(xml)". If any one could help I would appreciate it very much.
_xmlFile is my parsed document. I know it works because I have other methods using getTextContent() with specific tags and work well.
private void processFoo(Document _xmlFile){
               String xPath = null;
               String value = null;
               xPath = "/*/foo";
               try{
                    NodeList nodelist = XPathAPI.selectNodeList(_xmlFile, xPath);
                    for(int i2 = 0; i2 < nodelist.getLength(); i2++){
                    Element elem =(Element)nodelist.item(i2);
                    value = elem.toString();
                    value = value.replaceAll("\t", "");
                    value = value.replaceAll("\n", "");
                    value = value.replaceAll("\r", "");
               }catch(TransformerException transformerexception){
               addFoo(value);
public void addFoo(String _xml)
     String regex = null;
     String id = null;
     String content = null;
     Pattern pattern = null;
     Matcher matcher = null;
     String sql = null;
     int index = 0;
     String xml = _xml;
     regex = "\\<foo id=\"F(.+?)\">";
     pattern = Pattern.compile(regex);
     matcher = pattern.matcher(xml);
     while (matcher.find())
               id = matcher.group(1);
               id = id.replaceAll("'", "");
               index = matcher.end(1)+2;
               index = xml.indexOf("</foo>", index);
               content = xml.substring(matcher.end(1)+2, index);
               content = processOfString(content);
               sql = "INSERT INTO my.Foo (Foo_Id, Foo_Content) VALUES " + "(" + id + ", '" + content + "')";
               //System.out.println(sql);
               insertQuery(sql, false);
          xml = xml.substring(index+11, xml.length());
          matcher = pattern.matcher(xml);
}

Although I still have a question (which is at the bottom) I finally got what I wanted with the following method.
private void addFoo(Document _xmlFile){
String foocontent = null;
String fooref = null;
Document doc = _xmlFile;
String foopath = "foo";
String sql = null;
NodeList foo = doc.getElementsByTagName(foopath);
for (int i = 0; i < foo.getLength(); i++){
Element foos = (Element) foo.item(i);
fooref = foos.getAttribute("id");
foocontent = foos.getTextContent();
foocontent = foocontent.replaceAll("\t", "");
footcontent = footcontent.replaceAll("\n", "");
foocontent = foocontent.replaceAll("\r", "");
//System.out.println(fooref);
//System.out.print(foocontent);
sql = "INSERT INTO insider.footnote SET fooRef = ?, fooText = ?";
try{
PreparedStatement addfoo = con.prepareStatement(sql);
addfoo.setString(1, fooref);
addfoo.setString(2, foocontent);
addfoo.executeUpdate();
}catch(SQLException ex){
System.err.println("SQLException: " + ex.getMessage());
my foo table has a primary key that I need as a foreign key in ABC table. So I was wondering if there is anything in java that would allow me to send the key to ABC every time the foo table is updated. Actually, it would better if I can store the key in a variable that I send later with other data that needs to be input into the ABC table.
Thanks.

How to read value within XML Tag data using IO Stream in Java

We have xml data into a Stream and we need to extract values again into a Stream from the particular XML tag <Data> inside the Stream. PFB the sample XML which will be contained inside the stream and can someone help us to hint the java code for this. We require it using the IO API only and we need to look <DATA> for the begining of the stream and </DATA> as the end of the stream.
Please note that input is stream and output require also is a stream.
<?xml version = "1.0" encoding="UTF-8" ?>
<GenericDataEnvelope>
<DataFormat>PlainText</DataFormat>
<Name>1111</Name>
<Security>NA</Security>
<senderName>abc</senderName>
<Protocol>HTTP</Protocol>
<Data>
SElQRlhDVElQRlBCTktERUZGMDYxMDAyMDc0MzUyMDAwMTA2MTAwMjA3NDM1MlRDSEFTVVMzMzAw
MDAwMDAwMDAwMTc4LDEyMDAwMTc4MTIKezQ6TVQxMDM6CjoyMDowMDYwMDQ5MjQxMDA2NzcwCjoy
M0I6Q1JFRAo6MjNFOlNEVkEKOjMyQTowNjEwMDVDQUQwLDAxCjozM0I6RVVSMCwwMQo6MzY6MSwz

MTA2Ci19ClRJUEYK
</Data>
<DataType>INVOICE</DataType>
</GenericDataEnvelope>

The example you've showed is valid and it is also text.
Think seriously about this ... for example, do you have a rule that says </DATA> can't appear in the binary data?
But in any case I can't see the problem. If you want to use IO classes directly, just read lines until you see <DATA>, then read data until it ends with </DATA>, and remove that.
But I would certainly use SAX myself until proven otherwise that it won't work..

To show the data as a field with structure:
1. Query:
Select * from chipsxmltable1;
Output:
ID XMLDATA
1 <?xml version="1.0"?>
<samp:Field1 xmlns:samp="http://www.oradev.com/chipsxml.xsd">
<UTI>
<U01>No</U01>
<U02>No</U02>

<U03c>Y</U03c>
<U04>Y</U04>
<U05>Y</U05>
</UTI>
</samp:Field1>
2. Query: (Both the query displays the same Output)
     SELECT X.xmldata.getClobVal() "XMLDATA" FROM chipsxmltable1 X;
     select extract(XMLDATA, '/Field1').getstringval() "XMLDATA" from chipsxmltable1 x;
Output:
XMLDATA

<U03c>Y</U03c>
<U04>Y</U04>
<U05>Y</U05>
</UTI>
</samp:Field1>
To show the data as a single string without structure using "getstringval()":
3. Query
     select extract(XMLDATA, '//text()').getstringval() "CHIPS - XML" from chipsxmltable1 x;
OUtput:
CHIPS - XML
NoNoYYYYYY
To show the data as a single string without structure using "getclobval()":
4.Query
     select extract(XMLDATA, '//text()').getClobVal() "CHIPS - XML" from chipsxmltable1 x;
Output:
CHIPS - XML
NoNoYYYYYY
To show the data in a particular tag with/Without structure (Which is not working) using "EXTRACT" function:
6.Query:
     select extract(XMLDATA, '/Field1/text()').getstringval() "XMLDATA" from chipsxmltable1 x;
     select extract(XMLDATA, '/Field1/UTI').getstringval() "XMLDATA" from chipsxmltable1 x;
     select extract(XMLDATA, '/Field1/UTI/U01').getstringval() "XMLDATA" from chipsxmltable1 x;
     select extract(XMLDATA, '/Field1/UTI/U01/text()').getstringval() "XMLDATA" from chipsxmltable1 x;
Output:
CHIPS - XML
The above queries are not fetching the value.
To show the data in a particular tag with/Without structure (Which is not working) using "EXTRACTVALUE" function:
7. Query:
     select extractValue(XMLDATA, '/Field1/UTI') "XMLDATA" from chipsxmltable1 x;
     select extractValue(XMLDATA, '/Field1/UTI/U01') "XMLDATA" from chipsxmltable1 x;
Output:
X
The above queries are not fetching the value.
My question is:
How to fetch values from xml tag when the value are inserted through xml schema?
Apologies if the description is not clear. Kindly let me know if further details are needed. Many thanks for your help.
Very best regards,

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/functions051.htm#i1006712
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.
