Conversion of xml string to xml file
To convert xml string to xml file in java i used
Document XMLDoc=DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(new InputSource(new StringReader("<root><main>Title</main></root&g t;")));
But it is showing an error as InputSource cannot be resolved
How to rectify this
I assume you mean there is a compiler error? (It helps if you explain your problem instead of just giving a vague description of it.) It sounds like you have to import InputSource. You do know about the import statements that go at the beginning of a Java class, don't you?

Create Business Partner from XMl String not a file
Hi,
Is it possible to create a BP from an XML string.
I know about GetBusinessPartnerFromXml(string FileName, int index)
but I dont want to save the string in a file before creating a BP from it
Hope there's a method to do thatMarc,
This looks like it is a duplicate of this post, so I am closing this thread as it looks like you answered your own question!

XML string to XML parsing in JCD
I have stored an XML file as a CLOB in the Oracle DB. While fetching this data into JCD using Oracle OTD, I am getting this CLOB field as a string containing the XML. Now I want to parse this XML string to XML, as I need to map the individual fields to an XSD OTD, which will be my output.
Kindly suggest a way to achieve this.An XSD OTD has an unmarshalFromString() method:
inputFormat.unmarshalFromString( strData );
When putting the XML into the CLOB it could be a good idea to wrap an outputstream into a Writer object in order to make certain that the encoding is correct, depending how the data is represented. When retrieving CLOB data using getCharacterStream() you will get a Reader object where the encoding is already given. -

Hi All,
Can you please let me know for any sample code in xslt/java mapping for converting XML string into XML. We use SAP Pi 7.0
My XML string starts like this
<?xml version="1.0" encoding="UTF-8" ?>
- <ns0:MT_ReceiverFileStructure <namespace>"><Output><?xml version="1.0" encoding="ISO-8859-9"?><?xml-stylesheet type="text/xsl" href="<xsl>"?><Tarih_Date Tarih="11.09.2014" Date="09/11/2014>
Thanks,
PavithraThanks Praveen. It worked.
However, the xml i have is an extract from a exchange rate URL and it has the reference to a xsl in it as below
<?xml version="1.0" encoding="ISO-8859-9"?><?xml-stylesheet type="text/xsl" href="<ABC.xsl>"?>.
So there is an error in sxmb_moni. Is it possible to remove this. -
How to convert xml String to xml file?
Hi,
I got a method that do the following:
public static String convertXmlToString(String xmlFileName) throws Exception
File file = new File(xmlFileName);
FileInputStream insr = new FileInputStream(file);
byte[] fileBuffer = new byte[(int)file.length()];
insr.read(fileBuffer);
insr.close();
return new String(fileBuffer);
}The return String is the contents of an existing xml file and one example is shown below:
<object type="server.WOXReference" id="0"><field name="actualPathObj"><object type="java.lang.String" id="1">C:\restClient\actualXMLObjects\812856084.xml</object></field><field name="object"><object type="server.WOXConstructor" id="2"><field name="className"><object type="java.lang.String" id="3">rec.SimpleRecognizer</object></field><field name="types"><array type="java.lang.String" length="3" id="4"><object type="java.lang.String" id="5">double[].class</object><object type="java.lang.String" id="6">double.class</object><object idref="6" /></array></field><field name="args"><array type="java.lang.Object" length="3" id="7"><array type="double" length="5" id="8">22.33 33.22 33.33 22.0 11.0</array><object type="java.lang.Double" id="9">2.2</object><object type="java.lang.Double" id="10">3.3</object></array></field><field name="retType"><object type="java.lang.String" id="11">act</object></field></object></field></object>
and I want to change the above string to xml file like below:
<object type="server.WOXReference" id="0"><field name="actualPathObj"><object type="java.lang.String" id="1">C:\restClient\actualXMLObjects\812856084.xml</object></field><field name="object"><object type="server.WOXConstructor" id="2"><field name="className"><object type="java.lang.String" id="3">rec.SimpleRecognizer</object></field><field name="types"><array type="java.lang.String" length="3" id="4"><object type="java.lang.String" id="5">double[].class</object><object type="java.lang.String" id="6">double.class</object><object idref="6" /></array></field><field name="args"><array type="java.lang.Object" length="3" id="7"><array type="double" length="5" id="8">22.33 33.22 33.33 22.0 11.0</array><object type="java.lang.Double" id="9">2.2</object><object type="java.lang.Double" id="10">3.3</object></array></field><field name="retType"><object type="java.lang.String" id="11">act</object></field></object></field></object>How to I change the above xml String back to xml file again? The appropriate tags must be taken care of like > must be > and < must be <.
Please advice and can give me some sample code.
Thanks.By writing some code that runs through the file and adds a new line for a new element using these methods here...
http://java.sun.com/j2se/1.4.2/docs/api/org/xml/sax/ContentHandler.html

Convert xml string into xml file?
Hi,
I got a method that returns an JDom Element object.
Then I use the JDOM Element toString method() to change it into xml string.
Now, I need to convert it into actual xml file.
How to I do it?
Thanks.Hi,
If you got an xml string, just write it to an ordinary file. Look at FileWriter.

Someone, any idea?
My code:
try

parser.parse(xmlFileName);
Document doc = parser.getDocument(); // the document we will insert node into
Node root = doc.getElementsByTagName("jdbc-data-source").item(0);
//get XML string node

InputSource inStream = new InputSource();
inStream.setCharacterStream(new StringReader(xmlString));
Document doc4XMLString = db.parse(inStream);
Node rootXMLString = doc4XMLString.getElementsByTagName("jdbc-driver-params").item(0);
root.appendChild(doc.importNode(rootXMLString, true));
return true;
catch (Exception e)
e.printStackTrace();

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. -
Writing a large xml string to a file
Hi,
I get a large xml file, into a String (It might be around 8 MB also). After this, I need to write this to a file. Which java method I can use for the same.
I am getting confused by the various classes for writing a file.
I want to use the best, efficient way of doing this. Can any one please help?

But is there any any particular reason for using the encoding specific to xml?Yes, because that's what the XML specification says you're supposed to do. If you don't do that then you may produce malformed XML.
Will there be any perf degrade or truncation of the large string, while writing to the file, if we use,
out.write(sigUpdateString);Compared to what? You're just writing the data out to a file, the quickest way to do that is to just write the data out. The two things you should do are: (1) use a BufferedWriter (2) stop obsessing about performance. -

AshishHi Ashish,
As usual use our XSLT mapping to do it, its pretty simple using XSLT. But you can also achieve this with other mappings but XSLT is simple for this kind of job. Can you post the target structure in XML format. So that it will be easy for us to help you in XSLT.

Extracting elements from an xml string - org.apache.xerces.dom.DeferredText
Hello all,
I am new to xml, and I thought I had a handle on things until I got this problem...I am getting an xml string from the body of an e-mail message, and then I am trying to extract elements out of it. Here is an example xml string:
<?xml version="1.0" encoding="UTF-8"?>
<filterRoot>
<filter action="MOVE" bool="AND" name="My Saved Filter" target="Deleted Items">
<condition attribute="TO" bool="AND" contains="CONTAINS">
<value>[email protected]</value>
<value>[email protected]</value>
<value>[email protected]</value>
<value>[email protected]</value>
<value>[email protected]</value>
</condition>
</filter>
</filterRoot>I am trying to extract the <filter> element out and store it into a Vector of Elements (called, not surprisingly, filters). However, I am getting a class cast exception:
java.lang.ClassCastException: org.apache.xerces.dom.DeferredTextImplIt is being called from where I trying to extract the <filter> in this way:
filterRoot = doc.getDocumentElement(); // get topmost element
NodeList list = filterRoot.getChildNodes();
Vector newFilters = new Vector();
debug("There are "+list.getLength()+" filters in document");
for(int i=0; i<list.getLength(); i++) {
Node n = list.item(i);
debug("Node "+i+" getNodeValue() is "+n.getNodeValue());
Element temp = (Element)n;
newFilters.add(temp);
}Perhaps my question is, how do I correctly get hold of the <filter> node so that I may cast it as an Element?
thanks,
RizYes, I already knew that it is not a bug.
But, I got next step problem.
I put "false" to "include-ignorable-whitespace" feature in xerces parser.
But, I still found unnecessary TextNodes in my parser object.
Feature link : http://xerces.apache.org/xerces-j/features.html.
I use xerces-2_8_0.
DOMParser parser = new DOMParser();
parser.setFeature("http://apache.org/xml/features/dom/include-ignorable-whitespace", false);
parser.parse(inputSource);
document = ps.getDocument();
System.out.println(document.getDocumentElement().getChildNodes().length()); // still wrong lengthIs tehre any example of usage this feature?
What is default defination of white-space "\n "(enter with one space) or " "(juz white space) or something else?

Error after transforming xml string
I have an XML string that I have to parse and update (transformer)
String ji = "<book><person><first>p</first><last>m</last><age>22</age></person><person><first>b</first><last>g</last><age>46</age></person><person><first>s</first><last>j</last><age>40</age></person></book>";
ByteArrayInputStream str = new ByteArrayInputStream(ji.getBytes());
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = documentBuilderFactory.newDocumentBuilder();
Document doc = docBuilder.parse(str);
doc.getDocumentElement().normalize();
str.reset();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
NodeList listOfPersons = doc.getElementsByTagName("person");
int total = listOfPersons.getLength();
for(int i = 0; i < total; i++)
Node firstpersonnode = listOfPersons.item(i);
if(firstpersonnode.getNodeType() == Node.ELEMENT_NODE)
Element firstPersonElement = (Element)firstpersonnode;
NodeList firstNameList = firstPersonElement.getElementsByTagName("first");
Element firstNameElement = (Element)firstNameList.item(0);
NodeList textFNList = firstNameElement.getChildNodes();
Text t = (Text) textFNList.item(0);
String p = t.toString();
System.out.println("First Name : " +p);
t.setData("sdasdsa");
//String q = t.toString();
//response.write("First Name : " +q);
NodeList lastNameList = firstPersonElement.getElementsByTagName("last");
Element lastNameElement = (Element)lastNameList.item(0);
NodeList textLNList = lastNameElement.getChildNodes();
System.out.println("Last Name : " + ((Node)textLNList.item(0)).getNodeValue().trim());
NodeList ageList = firstPersonElement.getElementsByTagName("age");
Element ageElement = (Element)ageList.item(0);
NodeList textAgeList = ageElement.getChildNodes();
System.out.println("Age : " + ((Node)textAgeList.item(0)).getNodeValue().trim());
I then write the ByteArrayOutputStream to an OutputStream becoz I need it in that format for the Transformer.
oos = bos;
str.reset();
Source source = new DOMSource(doc);
Result res = new StreamResult(oos);
Transformer x = TransformerFactory.newInstance().newTransformer();
x.transform(source,res);
System.out.println("now the string is = "+oos.toString());
Which Transforms it:
Now my output is the Old XML string + some xml declaration + the Updated XML string.
First Name : p
Last Name : m
Age : 22
First Name : b
Last Name : g
Age : 46
First Name : s
Last Name : j

now the string is = <book><person><first>p</first><last>m</last><age>22</age></person><person><first>b</first><last>g</last><age>46</age></person><person><first>s</first><last>j</last><age>40</age></person></book><?xml version="1.0" encoding="utf-8"?>

I only need to update the stringClap... here is the compilable code complete:
Tried to make it shorter...:
public class TestXML {
public static void main(String[] args) {
String ji = "<book><person><first>p</first><last>m</last><age>22</age></person><person><first>b</first><last>g</last><age>46</age></person><person><first>s</first><last>j</last><age>40</age></person></book>";
ByteArrayInputStream str = new ByteArrayInputStream(ji.getBytes());
ByteArrayOutputStream os=null;
OutputStream oos = null;
try
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = documentBuilderFactory.newDocumentBuilder();
Document doc = docBuilder.parse(str);
doc.getDocumentElement().normalize();
str.reset();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
NodeList listOfPersons = doc.getElementsByTagName("person");
int total = listOfPersons.getLength();
for(int i = 0; i < total; i++)
Node firstpersonnode = listOfPersons.item(i);
if(firstpersonnode.getNodeType() == Node.ELEMENT_NODE)
Element firstPersonElement = (Element)firstpersonnode;
NodeList firstNameList = firstPersonElement.getElementsByTagName("first");
Element firstNameElement = (Element)firstNameList.item(0);
NodeList textFNList = firstNameElement.getChildNodes();
Text t = (Text) textFNList.item(0);
String p = t.toString();
System.out.println("First Name : " +p);
t.setData("sdasdsa");
NodeList lastNameList = firstPersonElement.getElementsByTagName("last");
Element lastNameElement = (Element)lastNameList.item(0);
NodeList textLNList = lastNameElement.getChildNodes();
System.out.println("Last Name : " + ((Node)textLNList.item(0)).getNodeValue().trim());
NodeList ageList = firstPersonElement.getElementsByTagName("age");
Element ageElement = (Element)ageList.item(0);
NodeList textAgeList = ageElement.getChildNodes();
System.out.println("Age : " + ((Node)textAgeList.item(0)).getNodeValue().trim());
byte b;
while ((b =(byte) str.read()) != -1) {
bos.write(b);
oos = bos;
str.reset();
Source source = new DOMSource(doc);
Result res = new StreamResult(oos);
Transformer x = TransformerFactory.newInstance().newTransformer();
x.transform(source,res);
System.out.println("now the string is = "+oos.toString());
catch(Exception e){System.out.println(e);}
}The o/p is as I mentioned in my first post

I have an XML string that I have to parse and update (transformer)
String ji = "<book><person><first>p</first><last>m</last><age>22</age></person><person><first>b</first><last>g</last><age>46</age></person><person><first>s</first><last>j</last><age>40</age></person></book>";
ByteArrayInputStream str = new ByteArrayInputStream(ji.getBytes());
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = documentBuilderFactory.newDocumentBuilder();
Document doc = docBuilder.parse(str);
doc.getDocumentElement().normalize();
str.reset();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
NodeList listOfPersons = doc.getElementsByTagName("person");
int total = listOfPersons.getLength();
for(int i = 0; i < total; i++)
Node firstpersonnode = listOfPersons.item(i);
if(firstpersonnode.getNodeType() == Node.ELEMENT_NODE)
Element firstPersonElement = (Element)firstpersonnode;
NodeList firstNameList = firstPersonElement.getElementsByTagName("first");
Element firstNameElement = (Element)firstNameList.item(0);
NodeList textFNList = firstNameElement.getChildNodes();
Text t = (Text) textFNList.item(0);
String p = t.toString();
System.out.println("First Name : " +p);
t.setData("sdasdsa");
//String q = t.toString();
//response.write("First Name : " +q);
NodeList lastNameList = firstPersonElement.getElementsByTagName("last");
Element lastNameElement = (Element)lastNameList.item(0);
NodeList textLNList = lastNameElement.getChildNodes();
System.out.println("Last Name : " + ((Node)textLNList.item(0)).getNodeValue().trim());
NodeList ageList = firstPersonElement.getElementsByTagName("age");
Element ageElement = (Element)ageList.item(0);
NodeList textAgeList = ageElement.getChildNodes();
System.out.println("Age : " + ((Node)textAgeList.item(0)).getNodeValue().trim());
}I then write the ByteArrayOutputStream to an OutputStream becoz I need it in that format for the Transformer.
oos = bos;
str.reset();
Source source = new DOMSource(doc);
Result res = new StreamResult(oos);
Transformer x = TransformerFactory.newInstance().newTransformer();
x.transform(source,res);
System.out.println("now the string is = "+oos.toString());
Which Transforms it:
Now my output is the Old XML string + some xml declaration + the Updated XML string.
First Name : p
Last Name : m
Age : 22
First Name : b
Last Name : g
Age : 46
First Name : s
Last Name : j
