Hi,
I am trying to write a PHP interface to ISBNdb.com. When I make a certain
request, the following is returned
<ISBNdb server_time="2009-02-24T18:57:31Z">
<BookList total_results="1" page_size="10" page_number="1"
shown_results="1">
<BookData book_id="language_proof_and_logic" isbn="157586374X"
isbn13="9781575863740">
<Title>Language, Proof and Logic</Title>
<TitleLong></TitleLong>
<AuthorsText>Jon Barwise, John Etchemendy, </AuthorsText>
<PublisherText publisher_id="center_for_the_study_of_la_a03">Center for
the Study of Language and Inf</PublisherText>
<Subjects>
<Subject
subject_id="amazon_com_nonfiction_philosophy_logic_language">Amazon.com --
Nonfiction -- Philosophy -- Logic & Language</Subject>
<Subject subject_id="amazon_com_science_general">Amazon.com -- Science
-- General</Subject>
</Subjects>
</BookData>
</BookList>
</ISBNdb>
And when loaded using simplexml_load_string, it gives the following object
object(SimpleXMLElement)#10 (2) {
["@attributes"]=>
array(1) {
["server_time"]=>
string(20) "2009-02-24T18:57:31Z"
}
["BookList"]=>
object(SimpleXMLElement)#14 (2) {
["@attributes"]=>
array(4) {
["total_results"]=>
string(1) "1"
["page_size"]=>
string(2) "10"
["page_number"]=>
string(1) "1"
["shown_results"]=>
string(1) "1"
}
["BookData"]=>
object(SimpleXMLElement)#11 (6) {
["@attributes"]=>
array(3) {
["book_id"]=>
string(24) "language_proof_and_logic"
["isbn"]=>
string(10) "157586374X"
["isbn13"]=>
string(13) "9781575863740"
}
["Title"]=>
string(25) "Language, Proof and Logic"
["TitleLong"]=>
object(SimpleXMLElement)#15 (0) {
}
["AuthorsText"]=>
string(30) "Jon Barwise, John Etchemendy, "
["PublisherText"]=>
string(40) "Center for the Study of Language and Inf"
["Subjects"]=>
object(SimpleXMLElement)#16 (1) {
["Subject"]=>
array(2) {
[0]=>
string(58) "Amazon.com -- Nonfiction -- Philosophy -- Logic &
Language"
[1]=>
string(32) "Amazon.com -- Science -- General"
}
}
}
}
Notice that I lose the attribute subject_id from the Subject tag. Why is
this?? Is there any way from preventing it from happening??
Thanks in advance,
Alex Chamberlain
