What is the best way to remove the line that matches a criteria as well as the line above it? For example, I have a text file that contains user names and addresses. I need to extract the user names and ID's for a confidential project:

Doe, John
<id:>123456789
<street:>1234 Broadway Circ.
<city:> Metropolis
<state:>XX
<phone:>000-000-0000

I am needing to remove the ID and name for each entry in the file. I would print the four lines below the ID, but some of the data is inconsistent such as no phone number, or no street info. Thanks for your help, you guys are great!

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
