How should i get the Link value from the below xml
XML Content
<document-instance system="abc.org" number-of-pages="6" desc="Drawing" link="www.google.com">
<document-format-options>
<document-format>application/pdf</document-format>
<document-format>application/tiff</document-format>
</document-format-options>
<document-section name="DRAWINGS" start-page="1" />
</document-instance>
i traverse update desc attribute after that i'm struggle
XPathExpression firstPageUrl = xPath.compile("//document-instance/#desc=\"Drawing\"]");
Expected output : retrieve the Link value
www.google.com
File file = new File("path to file");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(file);
XPath xPath = XPathFactory.newInstance().newXPath();
String expression = "//document-instance/#link";
Node node = (Node) xPath.compile(expression).evaluate(doc, XPathConstants.NODE);
String url= node.getTextContent();

I want get RECORD number based on contract id passed to java method. can any one help on this as i am new to XML parsing?
sample xml file:
<?xml version="1.0"?><FILE>
<Document RECORD="1"><Contract-Id>234</Contract-Id><Client-Id>232</Client-Id></Document>
<Document RECORD="2"><Contract-Id>235</Contract-Id><Client-Id>334</Client-Id></Document>
</FILE?
Java code:
File fXmlFile = new File(inputFile);
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document xmlDocument = dBuilder.parse(fXmlFile);
xmlDocument.getDocumentElement().normalize();
XPath xPath = XPathFactory.newInstance().newXPath();
XPathExpression xPathExpr = xPath.compile("//Document/Contract-Id[text()='"+ContractNumber+"']");
//Object result = xPathExpr.evaluate(xmlDocument,XPathConstants.NODESET);
Node nl = (Node)xPathExpr.evaluate(xmlDocument.getParentNode(), XPathConstants.NODESET);
nl.getTextContent();
nl.getAttributes();
Please try the following XPath expression:
/FILE/Document[Contract-Id="235"]/#RECORD
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;
DocumentBuilder db = null;
org.w3c.dom.Document document = null;
try {
dbf = DocumentBuilderFactory.newInstance();
db = dbf.newDocumentBuilder();
InputSource is = new InputSource(new ByteArrayInputStream(response.getBytes("UTF-8")));
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 am appending text to XML element iteratively like the following
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setValidating(false);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new FileInputStream(new File("./myXML.xml")));
Element element = doc.getDocumentElement();
NodeList node1 = doc.getElementsByTagName("name");
Element fn= (Element) node1.item(0);
Text text = doc.createTextNode(Content);
fn.appendChild(text);
printtoXML(doc);
My printXML method is updating xml by using TransformerFactory
fn.setTextContent() method does not work here,Because in every iteration it setting old text to new text.
I want to append Text iteratively, and in my next execution i want to delete old text contents of the particular element and append it again.
I have to execute the program many times for my testing and i don't want to append the same text again and again....
Could you please help me to solve this problem..
this might work
Text text;
void callsomefunctionthousendtimes(){
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setValidating(false);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new FileInputStream(new File("./myXML.xml")));
text = doc.createTextNode("");
Element element = doc.getDocumentElement();
NodeList node1 = doc.getElementsByTagName("name");
Element fn= (Element) node1.item(0);
//TODO call your functionName(content) 1000 times here
fn.appendChild(text);
printtoXML(doc);
}
void functionName(String content){
text = text.replaceWholeText(text.getWholeText() + content);
}
added bonusus, only load the doc in once
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 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
