jquery - How parsing xml from url get attribute javascript -

-

i need parsing xml url url xml

<?xml version="1.0" encoding="utf-8"?> <exchangerates>   <row>     <exchangerate ccy="rur" base_ccy="uah" buy="0.33291" sale="0.33291"/>   </row>   <row>     <exchangerate ccy="eur" base_ccy="uah" buy="18.60253" sale="18.60253"/>   </row>   <row>     <exchangerate ccy="usd" base_ccy="uah" buy="14.97306" sale="14.97306"/>   </row> </exchangerates>

i whant attribute using "14.97306" convert currency

(like mycurrency = 10 ) (like usd = 14.97306 ) (mycurrency * usd = 149.7306)

here's rudimentary setup java. you'll need read on xpath queries, , need add exception handling etc. i'm sure started.

    // open url     url url = ....     inputstream = url.openstream();      // build document parser     documentbuilderfactory domfactory = documentbuilderfactory.newinstance();     domfactory.setnamespaceaware(true);     documentbuilder builder = domfactory.newdocumentbuilder();      // parse document url     document d = builder.parse(is);      // set xpath examine/query xml     xpathfactory factory = xpathfactory.newinstance();     xpath xpath = factory.newxpath();      // use xpath query find required information     string sale = xpath.evaluate("/exchangerates/row[@ccy='usd']/@sale", d);      system.out.println("usd sale "+sale);
