## Re: [xsl] Group consecutive elements based on child content

 Subject: Re: [xsl] Group consecutive elements based on child content From: "Dimitre Novatchev" Date: Fri, 7 Sep 2007 09:08:47 -0700
```This is an example of not well defined problem.

In

>    <duration>
>        <nights>11</nights>
>        <price>111</price>
>        <price>222</price>
>        <price>333</price>
>        <price>444</price>
>        <price>-</price>
>    </duration>
>    <duration>
>        <nights>14</nights>
>        <price>999</price>
>        <price>222</price>
>        <price>333</price>
>        <price>444</price>
>        <price>-</price>
>    </duration>

will the two

>        <price>-</price>

elements match the corresponding previous

>     <price>555</price>

element, or will they match the vrresponding following

>        <price>456</price>

element?

In no way should both matchings be allowed, because then this
"quality" is no longer an equivalence relation -- it will follow that
555 = 456 and in fact that any two numbers are "equal"

The problem thus defined makes no sense.
