                        }
        ' file
myadminhost

This is more close to my request as it considers the first <server> tag only. However,

1. I would like read the result in a variable (myhost) and

2. for another tag <listen-port> if missing in the first <server> tag then would like to assign "7001" to "myport" variable.

LEARN ABOUT PHP

id3_remove_tag

ID3_REMOVE_TAG(3)							 1							 ID3_REMOVE_TAG(3)

id3_remove_tag - Remove an existing ID3 tag

SYNOPSIS

       bool id3_remove_tag (string  $filename, [int  $version = ID3_V1_0])

DESCRIPTION

       id3_remove_tag(3) is used to remove the information stored of an ID3 tag.

PARAMETERS

	      o $filename
		- The path to the MP3 file  Instead of a filename you may also pass a valid stream resource

	      o $version
		- Allows you to specify the version of the tag as MP3 files may contain both, version 1.x and version 2.x tags.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      id3_remove_tag(3) example

	      <?php
	      $result = id3_remove_tag( "path/to/example.mp3", ID3_V1_0 );
	      if ($result === true) {
		  echo "Tag successfully removed
";
	      }
	      ?>

	       If the file is writable and contained a 1.0 tag, this will output:

	      Tag successfully removed

NOTES

       Note

	       Currently  id3_remove_tag(3)  only supports version 1.0 and 1.1. If you choose to remove a 1.0 tag and the file contains a 1.1 tag,
	      this tag will be removed, as v1.1 is only an extension of 1.0.

SEE ALSO

       id3_set_tag(3), id3_get_tag(3), id3_get_version(3).
