                        }
        ' 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.

id3_get_version - Get version of an ID3 tag

SYNOPSIS
int id3_get_version (string $filename) DESCRIPTION
id3_get_version(3) retrieves the version(s) of the ID3 tag(s) in the MP3 file. If a file contains an ID3 v1.1 tag, it always contains a 1.0 tag, as version 1.1 is just an extension of 1.0. PARAMETERS
o $filename - The path to the MP3 file Instead of a filename you may also pass a valid stream resource RETURN VALUES
Returns the version number of the ID3 tag of the file. As a tag can contain ID3 v1.x and v2.x tags, the return value of this function should be bitwise compared with the predefined constants ID3_V1_0, ID3_V1_1 and ID3_V2. EXAMPLES
Example #1 id3_get_version(3) example <?php $version = id3_get_version( "path/to/example.mp3" ); if ($version & ID3_V1_0) { echo "Contains a 1.x tag "; } if ($version & ID3_V1_1) { echo "Contains a 1.1 tag "; } if ($version & ID3_V2) { echo "Contains a 2.x tag "; } ?> The above example will output something similar to: Contains a 1.x tag Contains a 1.1 tag SEE ALSO
