plugin to split a post

Hi,

I know using the quicktag <!–netxpage–> I can split a post. The problem with it is there isn’t a way to view the entire post. So, if someone wish to print the entire post it’s not possible.
I’m using a plugin to split my post called pagepost (http://www.coolcode.cn/?p=115). This has the possibility to show all the post or page by page. The problem with it is itsn’t W3C compatible, and I get this kind of errors:

# Error Line 122 column 108: character “=” is not allowed in the value of attribute “name”.

a name=”pp=0″ a name=”pp=1″

It is possible that you violated the naming convention for this attribute. For example, id and name attributes must begin with a letter, not a digit.

# Error Line 122 column 111: document type does not allow element “a” here; missing one of “object”, “span”, “bdo”, “applet”, “iframe”, “tt”, “i”, “b”, “u”, “s”, “strike”, “big”, “small”, “font”, “em”, “strong”, “dfn”, “code”, “q”, “samp”, “kbd”, “var”, “cite”, “abbr”, “acronym”, “sub”, “sup”, “label”, “ins”, “del” start-tag.

a name=”pp=0″ a name=”pp=1″ a name=”pp=2″

The mentioned element is not allowed to appear in the context in which you’ve placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you’ve forgotten to close a previous element.

One possible cause for this message is that you have attempted to put a block-level element (such as “” or “<table>”) inside an inline element (such as ““, “<span>”, or “<font>”).

So, someone can give the name of a plugin to split a post with the characteristics I wish ?
Or is there a way to hack the wordpress code to show also the option “all the post” when I use <!–nextpage–> ??

Thank you !
