String response = "<?xml version='1.0'?><soap:Envelope xmlns:soap='http://www.w3.org/2003/05/soap-envelope'><soap:Body><exch:Response xmlns:exch='http://applicant.ffe.org/exchange/1.0'>...</exch:Response></soap:Body></soap:Envelope>";
DocumentBuilderFactory dbf = null;

document = db.parse(is);
} catch(ParserConfigurationException e){}
catch(SAXException e){}
document is returning with null. I have tried different ways to pass to InputSource, but document is still returning null. Any idea why this might be happening?
I just tried i could get the elements name and values .
try {
dbf = DocumentBuilderFactory.newInstance();
db = dbf.newDocumentBuilder();
InputSource is = new InputSource(new ByteArrayInputStream(response.getBytes("UTF-8")));
document = db.parse(is);
System.out.println(document);//here we get null;
System.out.println(document.getNodeName());//here we get document;
for(int i =0 ; i<document.getChildNodes().getLength();i++)
System.out.println(document.getChildNodes().item(i).getChildNodes().item(i).getNodeName());
}
Output :
[#document: null]
document
soap:Body
To parse SOAPResponse we can javax.xml.soap.* it may take u to traverse the object xml tree. Anyway we may need parse the elements from SOAP Body . we could parse these very simple manner using DOM format .

I have converted a string to an XML document using the code below:
String xmlStr = "<msg><uuid>12345</uuid></msg>"
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder;
try {
builder = factory.newDocumentBuilder();
Document doc = builder.parse(new InputSource(new StringReader(xmlStr)));
return doc;
} catch (Exception e) {
throw new RuntimeException(e);
}
Then I converted an XML file to a document with the following:
File file = new File("src/test/resources/xmlForJunitTest.xml");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document expectedDoc = db.parse(file);
Finally I compare the two documents:
Document actualDoc = XmlUtils.convertStringToDocument(xmlString);
Diff myDiff = new Diff(expectedDoc, actualDoc);
assert (myDiff.similar());
This test passes using an XML file (xmlForJunitTest.xml) formatted like so:
<msg><uuid>12345</uuid></msg>
And it fails with this:
<msg>
<uuid>12345</uuid>
</msg>
Please you can suggest why this failure occurs, and what the solution is?
The assertion fails because one document includes whitespace, and the other doesn't. I believe you need to look at the normalizeWhitespace flag in XmlUnit (assuming that's what you're using).
My xml file looks like this
<InNetworkCostSharing>
<FamilyAnnualDeductibleAmount>
<Amount>6000</Amount>
</FamilyAnnualDeductibleAmount>
<IndividualAnnualDeductibleAmount>
<NotApplicable>Not Applicable</NotApplicable>
</IndividualAnnualDeductibleAmount>
<PCPCopayAmount>
<CoveredAmount>0</CoveredAmount>
</PCPCopayAmount>
<CoinsuranceRate>
<CoveredPercent>0</CoveredPercent>
</CoinsuranceRate>
<FamilyAnnualOOPLimitAmount>
<Amount>6000</Amount>
</FamilyAnnualOOPLimitAmount>
<IndividualAnnualOOPLimitAmount>
<NotApplicable>Not Applicable</NotApplicable>
</IndividualAnnualOOPLimitAmount>
</InNetworkCostSharing>
I am trying to get Amount value from <FamilyAnnualDeductibleAmount> and also from <FamilyAnnualOOPLimitAmount>. How do i get those values in java?
You may use two XPath queries /InNetworkCostSharing/FamilyAnnualDeductibleAmount and InNetworkCostSharing/FamilyAnnualOOPLimitAmount or just get the node InNetworkCostSharing and retrieve the values of its two direct children.
Solution using XPath:
// load the XML as String into a DOM Document object
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
ByteArrayInputStream bis = new ByteArrayInputStream("YOUR XML".getBytes());
Document doc = docBuilder.parse(bis);
// XPath to retrieve the content of the <FamilyAnnualDeductibleAmount> tag
XPath xpath = XPathFactory.newInstance().newXPath();
XPathExpression expr = xpath.compile("/InNetworkCostSharing/FamilyAnnualDeductibleAmount/text()");
String familyAnnualDeductibleAmount = (String)expr.evaluate(doc, XPathConstants.STRING);
StAX based solution:
XMLInputFactory f = XMLInputFactory.newInstance();
XMLStreamReader rdr = f.createXMLStreamReader(new FileReader("test.xml"));
while (rdr.hasNext()) {
if (rdr.next() == XMLStreamConstants.START_ELEMENT) {
if (rdr.getLocalName().equals("FamilyAnnualDeductibleAmount")) {
rdr.nextTag();
int familyAnnualDeductibleAmount = Integer.parseInt(rdr.getElementText());
System.out.println("familyAnnualDeductibleAmount = " + familyAnnualDeductibleAmount);
} else if (rdr.getLocalName().equals("FamilyAnnualOOPLimitAmount")) {
rdr.nextTag();
int familyAnnualOOPLimitAmount = Integer.parseInt(rdr.getElementText());
System.out.println("FamilyAnnualOOPLimitAmount = " + familyAnnualOOPLimitAmount);
}
}
}
rdr.close();
Note that StAX is especially good for cases like yours, it skips all unnecessary elements reading only the ones you need
Try something like this(use getElementsByTagName to get the parent nodes and then get the value be reaching out to child node):
File xmlFile = new File("NetworkCost.xml");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(xmlFile );
doc.getDocumentElement().normalize();
NodeList nList = doc.getElementsByTagName("FamilyAnnualDeductibleAmount");
String familyDedAmount = nList.item(0).getChildNodes().item(0).getTextContent();
nList = doc.getElementsByTagName("FamilyAnnualOOPLimitAmount");
String familyAnnualAmount =
nList.item(0).getChildNodes().item(0).getTextContent();
I think I found the solution with this question from stackoverflow
Getting XML Node text value with Java DOM
I'm making a webservice call in my Java code and getting the response as String with the below data.
<DocumentElement>
<ResultSet>
<Response>Successfully Sent.</Response>
<UsedCredits>1</UsedCredits>
</ResultSet>
</DocumentElement>
Now, I want to parse the below response String and get the value of <Response> tag alone for further processing. Since, I'm getting only the CDATA content how to parse the String content?
You obviously need XML parser for this one. Lets say the above is stored in a String variable named content
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
try {
//Using factory get an instance of document builder
DocumentBuilder db = dbf.newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(content)); //content variable holding xml records
Document doc = db.parse(is)
/* Now retrieve data from xml */
NodeList nodes = doc.getElementsByTagName("ResultSet");
Element elm = (Element) nodes.item(0); //will get you <Response> Successfully Sent.</Response>
String responseText = elm.getFirstChild().getNodeValue();
}catch(ParserConfigurationException pce) {
pce.printStackTrace();
}catch(SAXException se) {
se.printStackTrace();
}catch(IOException ioe) {
ioe.printStackTrace();
}
Follow the above parser routine for larger data sets. Use loops for multiple similar data sets. Hope that helps.
I have this xml:
InputStream is = new ByteArrayInputStream(
"<data:RobCtiAifoData xmlns:data=\"urn:cz:isvs:rob:schemas:RobDotazyData:v1\" xmlns:reg=\"urn:cz:isvs:reg:schemas:RegTypy:v1\" xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:urn=\"urn:cz:isvs:rob:schemas:RobUnivDotazy:v1\"><data:Aifo a=\"b\">1</data:Aifo><data:VyuzitiPoskytnuti>vyuziti</data:VyuzitiPoskytnuti> </data:RobCtiAifoData>"
.getBytes());
// InputStream is = new ByteArrayInputStream(xml.getBytes());
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse(is);
Node node = document.getDocumentElement();
when wanna get name of element without namespace so I wanna call substring of name of element withou prefix
node.getNodeName() gives me data:VyuzitiPoskytnuti
and node.getNamespaceURI() or node.getPrefix() gives me just null. So how I can get prefix of node ?
Try enabling namespace support:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
From the JavaDoc for setNamespaceAware:
Specifies that the parser produced by this code will provide support for XML namespaces. By default the value of this is set to false
I have a case like getting an XML and convert the XML elements to document object and getting the element values and attributes which i have been created already
Here is the piece of code i have tried to convert the string to DOM document object
String xmlString = " <r><e>d</e></r>";
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
org.w3c.dom.Document document = builder.parse(new InputSource(new StringReader(xmlString)));
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(new StringWriter());
transformer.transform(source, result);
String str1 = result.getWriter().toString();
System.out.println(str1);
But this case is valid for only elements without attributes
what can we do if the
String xmlString = "<element attribname="value" attribname1="value1"> pcdata</element>"
we are using Double quotes for the attribute values"value". The compiler is showing error
Suggest me if there any xml encoder and decoder is there to handle this scenarios ??
you can try
DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader("<root><node1></node1></root>"));
Document doc = db.parse(is);
refer this http://www.java2s.com/Code/Java/XML/ParseanXMLstringUsingDOMandaStringReader.htm
Either escape the double quotes with \
String xmlString = "<element attribname=\"value\" attribname1=\"value1\"> pcdata</element>"
or use single quotes instead
String xmlString = "<element attribname='value' attribname1='value1'> pcdata</element>"
DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document document = db.parse(new ByteArrayInputStream(xmlString.getBytes("UTF-8"))); //remove the parameter UTF-8 if you don't want to specify the Encoding type.
this works well for me even though the XML structure is complex.
And please make sure your xmlString is valid for XML, notice the escape character should be added "\" at the front.
The main problem might not come from the attributes.
public static void main(String[] args) {
final String xmlStr = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>\n"+
"<Emp id=\"1\"><name>Pankaj</name><age>25</age>\n"+
"<role>Developer</role><gen>Male</gen></Emp>";
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder;
try
{
builder = factory.newDocumentBuilder();
Document doc = builder.parse( new InputSource( new StringReader( xmlStr )) );
} catch (Exception e) {
e.printStackTrace();
}
}
