Calling `parse_node()` twice in order to avoid a temporary variable, is very unlikely to effect a performance gain. Unless `parse_node()` does almost nothing, in which case you would certainly gain more by in-lining it code in the loop. The grep solution will almost certainly prove faster. Either way, it probably isn't worth the effort unless this is likely to be called thousands or millions of times. My philosophy is "Optimise if it is worth it!". And that means concentrating ones effort where gains are likely to be measurable -- in the overall runtime. With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice. The start of some sanity?	[reply] [d/l] [select]

Where is the difference? In the number of times `parse_node` is called, for starters.	[reply] [d/l]
