Re^3: How can I keep or discard certain blocks of an XML file based on first line of block?by Anonymous Monk |

I discovered one more wrinkle. I didn't think the label_y blocks at the top of the file were important, but it turns out they are. Remember the format of those is:
What I need to do is this: Discard all but the first (or last, doesn't matter) of these, so there is only one such block in the file. Or, discard all of them and create a replacement - it would not really matter, just so there is only one. If keeping one of the original blocks, save "somevalue" from the first line in a variable such as $somevalue. Then, lower in the program, before writing the "kept" label_a blocks to the output file, I need to do this: $e->set_att( 'channel' => $somevalue );Since what's been posted so far is far more elegant than anything I would have come up with, I'd be interested in knowing a good way to do discard all (or all but one) of those initial blocks, and insert a replacement if needed, so there is only one. By the way, relative to my previous post I did discover keep_atts_order => 'TRUE', which works in Linux but for some reason not in ActivePerl in Windows.
