How to reduce the space between two lines?


I am retrieving data from a external .xml file. But there is a lot of space between two lines. How can I reduce it?

The attached file shows the space between sentences.

The following is the xml code:

<?xml version="1.0" encoding="utf-8"?>
<Header>Contact Details</Header>
Name :
Telephone :
Cell Phone : 

Thanks in advance for any help.
