avoiding repeated rule while reading xml

Question

I am doing yahoo API program where i am getting result as XML format and fetching values from that xml files using the rule name. But in my case the xml file looks like this.

<person>
  <first>Kiran</first>
  <first>sam</first>
  <url>www.aaaaaaaaddd.com</url>
  <last>Pai</last>
  <age>22</age>
  <url>www.ajsajha.com</url?
</person>
<person>
  <first>Kiran</first>
  <first>tom</first>
  <url>www.aaaaasdadd.com</url>
  <last>Pai</last>
  <age>22</age>
  <url>www.wqeqwjha.com</url>
</person>

In this i want to take values from the following rules : first, url, lat, age. But i want to take only one value from the rule first, url.

if(e.getElementsByTag("url")!=null)
              {
                  itemStringBuilder.append(e.getElementsByTag("url").text());

              }

when i use this code i am getting both the url values. How can i check and avoid the second one and just take the first.

Are you using plain java DOM parser? or any thir party libraries? Because in java there is no method called "getElementsByTag" it is "getElementsByTagName" — Hirak

Elements urls = e.getElementsByTag("url"):
if (urls != null)
{
    itemStringBuilder.append(urls.first().text());
}

Use first() on the Elements gotten. One call to get is more efficient.

Javadoc is your best friend.
