in thread XML::Parser XML validation

Thanks for your quick answer. So basically, I will have to fix any error found by the script and then re-run, fix any new error and repeat the procedure until there are no more errors?

    Yes. All bets are off for an XML document with errors. The first error found may actually not be the first error in the document: it is just the place where the parser got stuck.

    Consider the following:

    <a> <d> <e> </e> </b> </a>
    Where is the error? Should <d> be <b> or should </b> be </d>? Or perhaps they should both be <f> ... </f> tags? How is the parser to know? To be sure the XML is not only well formed but also correct, you will have to validate the XML according to a DTD or Schema definition.

There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James

[Discipulus]: i propend for removing: why? because we are so few that we must find i minimal common divisor, this is certainly Perl not our (anyway private) thougths. And i say this still wondering because i love a lot freedom of expression. And i say this not for roho
[1nickt]: Discipulus that was the point of my story of taking the sticker off my truck. I know there are lots of people in the world who if I knw their private beliefs I might want to argue with them. And they with me. But life cannot all be arguments!
[1nickt]: This is less than perfect ... but demanding perfection (from people or from life) is a sure way to unhappiness.
[Discipulus]: and anyway we have CB where every (democratic) opinion can be expressed
erix eat the rich!
[1nickt]: I do think it is sad that roho has received 3 downvotes for his polite request, as did I when I objected to the profanity in stonecolddevin's sig. I upvoted both him and Karl for the discussion. Way too much downvoting for inappropriate reasons here!
Discipulus learn that 'argue' has a little negative sense, he thought was a neutral sense, 'vox media'
[1nickt]: argue == discuss && argue == be contentious
[Discipulus]: you are right 1nickt i didnt voted nor downvoted; I just upvote perl content i like
[1nickt]: In Spanish, to argue (like a fight) is discutir -- does not mean to discuss !
