Re: New use need your help

[Nigel S. <nig...@us...>]

  The document said it needs an absolute XPath and the default parameter =
is the 'super-root',=20

  Isn't "/library/book[1]" a abolute Xpath?

Nope sorry, it's close, but you need to use:

"/library[1]/book[1]"

Even though there can be only one root node, the [1] is needed.

Cheers

Nigel

Re: New use need your help

[Nigel S. <nig...@us...>]

Because you are using the XML_OPTION_CASE_FOLDING option, you need to =
do:

$fdata =3D &$xPath->getNode('/LIBRARY[1]/BOOK[1]');

Sorry for the confusion.

Cheers

  Hi Nigel,
  Thanks for your reply. I tried what you said '/library[1]/book[1]', =
but it still return nothing.
  Can you try to run this small sample?
  It must be something else. but I don't know.

Re: New use need your help

[Nigel S. <nig...@us...>]

  Thank you for your kind reply, now I can find the data I want.=20

  But, I still couldn't find a way to count how many books are in the =
library?
count($xPath->match(/LIBRARY[1]/BOOK))
  And I want to import the all book data(title, author,pages,price etc.) =
into a php array and present them to the user in other format.(For =
example a HTML form select menu options)

  Is my idea workable with Xpath?
Yes very much so :o)  Something along the lines of:

$aBookAddress =3D $xPath->match('/LIBRARY[1]/BOOK');
foreach($aBookAddress as $BookAddress) {
    $aBook =3D array();
    $aBook['Title'] =3D $xPath->getData($BookAddress.'/title');
        $iISBN =3D $xPath->getAttribute($BookAddress.'/title', 'ISBN');
        $aBooks[$iISBN] =3D $aBook;
}

(The above is completely untested, written off the top of my head, but =
it's a good template to start from)

Cheers

Nigel
