Convert XML String to Map and get the key & value pairs using Java
提问by Syed
I have an XML String. I'm trying to convert that string into map so that I can get key & value. However its not able to convert. Here is my code
我有一个 XML 字符串。我正在尝试将该字符串转换为映射，以便我可以获得键和值。但是它无法转换。这是我的代码
String xmlString = "<?xml version="1.0" encoding="UTF-8"?><user>
<kyc></kyc>
<address></address>
<resiFI></resiFI></user>"
def convertStringToDocument = {
xmlString ->
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder;
try {
builder = factory.newDocumentBuilder();
org.w3c.dom.Document doc = builder.parse(new InputSource(new StringReader(xmlString)));
return doc;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
def populateDocProofsFromWaiversXML = {
xmlString, mandateFlag ->
final List<DocumentProof> documentProofs = new ArrayList<DocumentProof>();
if (xmlString != null) {
try {
HashMap<String, String> values = new HashMap<String, String>();
Document xml = convertStringToDocument(waiversList);
org.w3c.dom.Node user = xml.getFirstChild();
NodeList childs = user.getChildNodes();
org.w3c.dom.Node child;
for (int i = 0; i < childs.getLength(); i++) {
child = childs.item(i);
System.out.println(child.getNodeName());
System.out.println(child.getNodeValue());
values.put(child.getNodeName(), child.getNodeValue());
}
} catch (Throwable t) {
println "error"
//LOG.error("Could not set document proofs from waivers ", t);
}
}
return documentProofs;
}
I'd like to get "kyc" as key and the respective value. Any better ideas?
我想将“kyc”作为键和相应的值。有什么更好的想法吗？

This will work. Please check :) You can play with DOM.
这将起作用。请检查:) 你可以玩 DOM。
