How to Read Value from XML document and store it in a variable using Selenium Java -

i'm new automation using selenium java.

i have problem need go through xml file find node , read value in node. , need compare value input string.

can please me how read xml file , fetch value xml , store in variable.

this have in xml :

in image 01 need read value in chassismoduleoptionrequest partner_item= , store value in array.

below code tried.

documentbuilderfactory factory = documentbuilderfactory.newinstance(); documentbuilder builder = factory.newdocumentbuilder();                     //parsing of xml done here document doc = builder.parse(new file("c:\\users\\satish_d1\\documents\\my received files\\pdsl_abm.xml"));  //here root element of xml , print out doc.getdocumentelement().normalize(); system.out.println ("root element of doc " + doc.getdocumentelement().getnodename());  nodelist list = doc.getelementsbytagname("chassismoduleoptionrequest"); int totalpartneritem =list.getlength(); system.out.println("total no of partner item : " + totalpartneritem);           //traversing elements list , printing out data (int = 0; < list.getlength(); i++)  {      //getting 1 node list.     node childnode = list.item(i);     system.out.println("partner item : " + childnode.gettextcontent());  } 

we can use java inbuilt libraries create regex pattern , search in string(data in file). below code might give idea.

public static void main(string[] args) throws filenotfoundexception  {   //change path file   string content = new scanner(new file("/home/santhoshkumar/desktop/sample.xml")).usedelimiter("\\z").next();    //system.out.println(content);   //arraylist store values   arraylist<string> values = new arraylist<>();   //change pattern.   pattern pattern = pattern.compile("<cchassismoduleoptionrequest partner_item=\"(.*)\">");       matcher matcher = pattern.matcher(content);      while (matcher.find())    {         system.out.println(matcher.group(1));         values.add(matcher.group(1));   }     } 

hope helps. thanks.
