Ok thanks durden_tyler I forgot about the power of perl - it is a more elegant solution. That said the sed thing will still bother me for a bit.

Also I've realised I need to do a bit more work yet. In order to present the data in conky more flexibly I have realised that I need to execute the script in conky for each instance of tide time - that is separately. I suspect I will need to create a variable that can be passed from each of the lines in conky to the script which will have a perl loop that loops to the specific instance of tide time based on the passed variable. Looks like a bit of mugging up on perl may be required! Thanks again.

I'm a dunderhead. I can use tail and head to output the specific line of course. Problem solved.

Thanks again for the help.

xml::rss::libxml::magicelement

XML::RSS::LibXML::MagicElement(3pm)			User Contributed Perl Documentation		       XML::RSS::LibXML::MagicElement(3pm)

NAME

       XML::RSS::LibXML::MagicElement - Represent A Non-Trivial RSS Element

SYNOPSIS

	 us XML::RS::LibXML::MagicElement;
	 my $xml = XML::RSS::LibXML::MagicElement->new(
	   content => $textContent,
	   attributes => @attributes
	 );

DESCRIPTION

       This module is a handy object that allows users to access non-trivial RSS elements in XML::RSS style. For example, suppose you have an RSS
       feed with an element like the following:

	 <channel>
	   <title>Example</title>
	   <tag attr1="foo" attr2="bar">baz</tag>
	   ...
	 </channel>

       While it is simple to access the title element like this:

	 $rss->{channel}->{title};

       It was slightly non-trivial for the second tag. With this module, <tag> is parsed as a XML::RSS::LibXML::MagicElement object and then you
       can access all the elements like so:

	 $rss->{channel}->{tag};  # "baz"
	 $rss->{channel}->{tag}->{attr1}; # "foo"
	 $rss->{channel}->{tag}->{attr2}; # "bar"

METHODS

   new
       Create a new MagicElement object.

   attributes
       Returns the list of attributes associated with this element

   toString
       Returns the string representation of this object.  By default we use the "text content" of the found tag, but for XML::RSS compatibility,
       we use the concatenation of the attributes if no content is found.
