How to pass a XML document to XSL file using Javax.xml.transformer API?

I am using javax.xml.transform API to do XSL transformation . The API only allows one XML document as an input to apply transformation as below .
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
StringWriter stringWriter = new StringWriter();
File xml = new File("C:\\abc");
File xsl = new File("C:\\def.xsl");
factory.setNamespaceAware(true);
DocumentBuilder builder = factory.newDocumentBuilder();
document = builder.parse(xml);
TransformerFactory transformerFactory =
TransformerFactory.newInstance();
StreamSource style = new StreamSource(xsl);
Transformer transformer = transformerFactory.newTransformer(style);
DOMSource source = new DOMSource(document);
Also , can pass simple String params as below , without any issue as below :
transformer.setParameter("mode", "CREATE");
But , i want to pass an XML Document as a parameter to the XSL file . I tried below code as suggested on one of SO pages , as below :
DocumentBuilder builder = factory.newDocumentBuilder();
final Document documentFile = builder.parse(xml2);
Map<String, Document> docs = new HashMap<String, Document>();
docs.put("lookup", documentFile);
transformer.setURIResolver(new DocumentURIResolver(docs));
And i set , the tag in XML to receive value as below :
<xsl:variable name="lookup" select="('documentFile')/> .
But its not working for me . Can anyone help me out with the correct pay to pass multiple XML documents to any XSL file via javax.xml.transform API ?
Update
Still stuck with the issue ,can any one let me how can i pass XML object into a XSLT 2.0 stylesheet as a param . I have tried different approaches but no luck still . I need to know a way out via JAVA xsl transform API .

I think your issue is in the XSLT. Change
<xsl:variable name="lookup" select="('documentFile')/> .
to
<xsl:variable name="lookup" select="document('lookup')/>
this will cause the transformer to make the DOM of your document accessible in the variable lookup. The key lookup comes from docs.put("lookup", documentFile);
Dynamically Pass Multiple XML Sources to XSL Transformation via URIResolver.
Full Working Example:
Be there three XML files: repo.xml, books.xml and articles.xml. The repo.xml contains status information about books and articles. The files articles.xml and books.xml contain title information about each item. The goal is to print status information of all books and articles together with the title information. The entries in all files are connected via id keys.
Find complete example at github or copy/paste the listings below.
repo.xml
<repository>
<book>
<id>1</id>
<status>available</status>
</book>
<book>
<id>2</id>
<status>lost</status>
</book>
<article>
<id>1</id>
<status>in transit</status>

Did you already try this ?
org.w3c.dom.Document doc = ... // Your xml document
transformer.setParameter("demo", doc.getDocumentElement());

(Answer expanded to handle passing in a parsed W3C DOM document via a URIResolver)
This can be done in pure XSLT/XPath using the version of the Xalan XSLT processor that is supplied with the JRE.
As an example, say if the name of one of the input documents is passed in as a parameter to the Transformer:
File parentDir = new File("c:\\dir");
StringWriter stringWriter = new StringWriter();
File xml = new File(parentDir, "input.xml");
File xsl = new File(parentDir, "xslt-document-param.xslt");
Source xsltSource = new StreamSource(xsl);
Source xmlSource = new StreamSource(xml);
TransformerFactory transformerFactory = TransformerFactory
.newInstance();
Transformer transformer = transformerFactory.newTransformer(xsltSource);
transformer.setParameter("doc-name", "basic.xml");
transformer.transform(xmlSource, new StreamResult(stringWriter));
System.out.println(stringWriter);
This parameter can then be passed into the document() function in XPath as follows:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xalan="http://xml.apache.org/xalan"
version="1.0"
exclude-result-prefixes="xalan">
<xsl:output
method="xml"
indent="yes"
xalan:indent-amount="2"/>
<xsl:param name="doc-name"/>
<xsl:template match="/">
<xsl:variable name="doc-content" select="document($doc-name)"/>
<parent>
<xsl:for-each select="$doc-content/basic/*">
<child>
<xsl:value-of select="name(.)"/>
</child>
</xsl:for-each>
</parent>
</xsl:template>
</xsl:stylesheet>
This is able to read this basic.xml (from the parameter):
<basic>
<one/>
<two/>
<three/>
</basic>
And transform it to:
<parent>
<child>one</child>
<child>two</child>
<child>three</child>
</parent>
The parameter to the document() function is a URI. A relative path is resolved relative to the XSL file. Equally this could be a full URL, or resolved via a custom transformer.setURIResolver() as in the question.
(edit from here...)
To work with passing in a pre-parsed Document object to the XSLT, the URIResolver approach is able to handle passing this back to the document() function.
For example, with the lookup in the question:
File lookupXml = new File(parentDir, "basic.xml");
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(lookupXml);
Map<String, Document> docs = new HashMap<>();
docs.put("lookup", document);
transformer.setURIResolver((href, base) -> new DOMSource(docs.get(href)));
This XSL is able to iterate through the same basic.xml as above...
<xsl:template match="/">
<xsl:variable name="doc-content" select="document('lookup')"/>
<parent>
<xsl:for-each select="$doc-content/basic/*">
<child>
<xsl:value-of select="name(.)"/>
</child>
</xsl:for-each>
</parent>
</xsl:template>
... and output the same result.

Not sure about your issue , if you give usecase and ask how to solve will be more helpful insted of asking how to fix your code as we are not having end to end visiblity of your code and xml.
Following could be possible solution :
1) We can convert xml to string
try {
StringReader _reader = new StringReader("<xml>vkhan</xml>");
StringWriter _writer = new StringWriter();
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(
new javax.xml.transform.stream.StreamSource("styler.xsl"));//ur xsl
transformer.transform(
new javax.xml.transform.stream.StreamSource(_reader),
new javax.xml.transform.stream.StreamResult(_writer));
String result = writer.toString();
} catch (Exception e) {
e.printStackTrace();
}
2) Modify below code as per your requirments pass as List of object of call in for loop.
public class Data {
public static final Document transformXmlDocument(Document sourceDocument, InputStream xsltFile) {
DOMSource xmlSource = new DOMSource(sourceDocument);
StreamSource xsltSource = new StreamSource(xsltFile);
Document transformedData = null;
try {
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(xsltSource);
ByteArrayOutputStream output = new ByteArrayOutputStream();
StreamResult result = new StreamResult(output);
transformer.transform(xmlSource, result);
DocumentBuilder resultBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
transformedData = resultBuilder.parse(
new InputSource(
new StringReader(
new String(output.toByteArray())
)
)
);
} catch (Exception e) {
Log.e("XSLT Transformation", e.getMessage());
}
return transformedData;
}
}
https://gist.github.com/dazfuller/1559935/b84ee72db0e1de8ea25c54fbc744defbe4705ad9

Try to replace your <xsl:variable name="lookup" select="('documentFile')"/> instruction with <xsl:variable name="documentFile" select="document($lookup)"/> and pass your XML Document as a parameter with transformer.setParameter("lookup", "myfile.xml"); which means : load the document referenced by the lookup parameter into the documentFile variable.

XML to CSV conversion using java, tag with colon problem

I am not able to display the value of xml tag using namespace - tag with colon.
When there are no colons in tags, code works perfectly, but as soon I want to display a tag which contains colon, program doesnt throw any error, only doesn`t show any value.
Here is the XML:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:inv="http://www.w3schools.com/daco" xmlns:lst="http://www.esa.int/safe/sentinel-1.0" version="1.0">

DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(xmlSource);
StreamSource stylesource = new StreamSource(stylesheet);
Transformer transformer = TransformerFactory.newInstance()
.newTransformer(stylesource);
Source source = new DOMSource(document);
Result outputTarget = new StreamResult(new File("xyz.csv"));
transformer.transform(source, outputTarget);
System.out.println("done");
}
}
Codes really simplified to find the cause of the problem, but I was not able to figure it out.
If I would remove lst: from tag in xml and from xsl, it would work, as soon there is colon, program doesn`t show any value.
But XML we receive contain plenty of tags with colon, so I would a solution to this problem.
Please if you have any idea where could be the problem, please let me know :)
Expected output:

Try this;
public static void main(String args[]) throws Exception {
File stylesheet = new File("C:/java/howto.xsl");
File xmlSource = new File("C:/java/howto.xml");
// DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
// DocumentBuilder builder = factory.newDocumentBuilder();
// Document document = builder.parse(xmlSource);
StreamSource stylesource = new StreamSource(stylesheet);
Transformer transformer = TransformerFactory.newInstance()
.newTransformer(stylesource);
//Source source = new DOMSource(document);
Source source = new StreamSource(xmlSource);
Result outputTarget = new StreamResult(new File("C:/java/xyz.csv"));
transformer.transform(source, outputTarget);
System.out.println("done");
}

I want to read the data from this XML and store it in CSV file as below.
Column names should be the RootElementName_ChildElementName(if we have)_AttributeName. This format I should follow,
Suppose RootElement is FIXML and we have attributes "s" and "v" so the column name should be as follows FIXML_s, FIXML_v.
And the Child Elements Batch and MktDef the column names should be
FIXML_Batch_ID and FIXML_Batch_MktDef_MktID like that it follows.
1) FIXML_s FIXML_v FIXML_Batch_ID FIXML_Batch_MktDef_MktID . . . . .
"2012-04-23" "FIX.5.0SP2" RPTTA111PUBLI20170509 XEUR ....
.
.
.
We have data like that for thousands of lines and when it reaches to the "</SecDef>" the data should print in 2nd line and 3rd line like that it continues.
Can someone guide me on this. I am very new to working on XML data.

How to delete <?xml version="1.0" encoding="UTF-8" standalone="no"?> from xml document [duplicate]

This question already has answers here:
Remove 'standalone="yes"' from generated XML
(13 answers)
Closed 9 years ago.
I wrote code for tests - it creates simple XML document. My problem is that created document contains unneeded data in first node . Is any way to delete or modify this node <?xml version="1.0" encoding="UTF-8" standalone="no"?> ?

t.setOutputProperty(OutputKeys.INDENT, "yes");
t.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
t.transform(new DOMSource(doc),new StreamResult(s));
System.out.println(new String(s.toByteArray()));
} catch (ParserConfigurationException pce) {
pce.printStackTrace();
} catch (TransformerException tfe) {
tfe.printStackTrace();
}
}
}
It returns:

<salary>100000</salary>
</Staff>
</company>
Is any way to delete or modify this node <?xml version="1.0" encoding="UTF-8" standalone="no"?> ?

You can add the following to your Transformer
t.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");

how to get how many node with certain attributes with DOM

I have a task to parse an XML file with JDom in Eclipse. When I started to create the code, my code is only sufficient to get the length(how many) node with Tag name model. The task is more specific, I need to get the length of the node with tag name model which has attribute type. How should I modify my code to get the result?

You want to count the number of <model> elements that contains the type attribute? If, so XPath is the most suitable tool.
XPath xp = XPathFactory.newInstance().newXPath();
Double num = xp.evaluate("count(//model[#type])", doc, XPathConstants.NUMBER);
Btw, you are using DOM, not JDOM.
