First, I don't believe that an input can have a multiple attribute. A select can. And the inverse of multiple="multiple" is not multiple="false", it's simply the absence of the multiple attribute altogether. Any string at all in the value portion of the multiple attribute will signal that the attribute is true. And in HTML5, just having it there at all will have it work. These are all functionally identical:
<select name="foo" multiple="bar">...</select>
<select name="foo" multiple="true">...</select>
<select name="foo" multiple>...</select>
<select name="foo" multiple="multiple">...</select>
The last two are considered the normal form. To make a single-value select, you would use this instead:
<select name="foo">...</select>

Agree. libxml2 here is simply obeying the boolean convention around the "multiple" attribute, regardless of the tag.

But some jquery plugins require this multiple='true' indeed, can i turn off the correction??

See if you can use valid HTML code: either multiple="multiple" (or just multiple all by itself) if you're allowed to choose multiple values, and leave it off entirely if you aren't. And please confirm -- you are using this attribute on a <select> not an <input>, right?
If you are using jQuery, it should absolutely require you to start with valid HTML or XHTML. Browsers are endlessly forgiving of "tag soup" -- JavaScript catches cold and dies at the slightest sniffle of invalid HTML.
Finally, Nokogiri should not be doing anything to your <script> tag contents beyond a little whitespace cleanup from the prettifier. If this construction is inside a script block, it shouldn't be touched there at all, methinks.

Thank you Walter, i know THE jquery-plugin is the one to blame.
I temporarily replace the 'multiple' with some other 'blahblahattributename' and put it back later as a workaroundYou received this message because you are subscribed to a topic in the Google Groups "nokogiri-talk" group.
