You can access element order using the following trick. <?php $wsdl = "http://zx81.highlyillogical.org/~simon/phpbugtest/phpbugtest.wsdl";; $options=Array( 'typemap' => array(array("type_ns" => "http://zx81.highlyillogical.org/~simon/phpbugtest";, "type_name" => "sentence", "from_xml" => "sentence_from_xml")) ); function sentence_from_xml($x) { return simplexml_load_string($x); } $client = new SoapClient($wsdl, $options) ; $result = $client->bugtest(); var_dump($result); foreach ($result as $key => $val) { echo $key . ":" . (string)$val . "\n"; } Actual result: -------------- object(SimpleXMLElement)#2 (3) { ["other"]=> array(3) { [0]=> string(3) "The" [1]=> string(2) "is" [2]=> string(4) "with" } ["noun"]=> array(2) { [0]=> string(3) "cat" [1]=> string(6) "string" } ["verb"]=> string(7) "playing" } other:The noun:cat other:is verb:playing other:with noun:string Previous Comments: ------------------------------------------------------------------------ [2007-06-14 09:58:27] simon at highlyillogical dot org In practice, that's not possible. The 'words' example is a much-simplified example of what I want to happen. In reality my document is a sequence of objects of different types, but must remain in the correct order. Think of an XHTML document. It's valid XML and could theoretically be used in a similar way. However, in such a document you've got no idea whether a <p> element, a <ul> element, a <div>, a <form>, or a <table> is coming next... But they do have to have the order retained. If you globbed all of the paragraps together, with all of the unordered lists after, you'd end up with something that didn't make much sense. In fact, if you look at the schema for XHTML (http://www.w3.org/TR/xhtml1-schema/#xhtml1-strict) you can see that it uses exactly this mechanism (xs:choice maxOccurs="unbounded") in order to implement this. (See the "Block" complexType) -- So, if you want to parse soap messages with an XHTML payload correctly, a solution to this problem needs to be found. ------------------------------------------------------------------------ [2007-06-14 07:27:11] [EMAIL PROTECTED] I don's see a way to fix this. PHP is not able to keep several elemtns with the same names in object or array. So it is not possible to keep order of elements with different names. You can probaly change WSDL to have a sequence of 'words', where each word is an element defined as extension of type 'string' with 'part_of_speach' attribute. So you'll have to pass something like this: <sentence> <word part_of_speach="other">The</word> <word part_of_speach="noun">cat</word> <word part_of_speach="other">is</word> <word part_of_speach="verb">playing</word> <word part_of_speach="other">with</word> <word part_of_speach="noun">string</word> </sentence> ------------------------------------------------------------------------ [2007-05-24 13:36:13] simon at highlyillogical dot org Description: ------------ When the PHP soap client parses a SOAP response that contains multiple recurrences of an <xsd:choice maxOccurs="unbounded"> element, the ordering of elements can be lost, as the results are grouped by element type. For example, take the following complex type: <xsd:complexType name="sentence"> <xsd:choice maxOccurs="unbounded"> <xsd element name="noun" type="xsd:string" /> <xsd element name="verb" type="xsd:string" /> <xsd element name="other" type="xsd:string" /> </xsd:choice> </xsd:type> This type can describe a sentence, with one element per word. An example sentence might be: <sentence> <other>The</other> <noun>cat</noun> <other>is</other> <verb>playing</verb> <other>with</other> <noun>string</noun> </sentence> When PHP parses this, it groups the elements by type. Thus, a sentence which reads "The cat is playing with string", is mangled to read "cat string playing The is with" I've posted a wsdl to demonstrate the problem at: http://zx81.highlyillogical.org/~simon/phpbugtest/phpbugtest.wsdl A valid XML response similar to the case above is at: http://zx81.highlyillogical.org/~simon/phpbugtest/bugtest.xml To reproduce the problem, simply call the bugtest operation on the above wsdl. It will always return the above xml response. Reproduce code: --------------- $client = new SoapClient ( "http://zx81.highlyillogical.org/~simon/phpbugtest/phpbugtest.wsdl"; ) ; // we're just hitting an XML file, so we don't care about the input $result = $client->bugtest ( ) ; var_dump ( $result ) ; Expected result: ---------------- An output with the resulting objects are presented in the order in which they occurred in the document. Actual result: -------------- object(stdClass)#2 (3) { ["noun"]=> array(2) { [0]=> string(3) "cat" [1]=> string(6) "string" } ["verb"]=> string(7) "playing" ["other"]=> array(3) { [0]=> string(3) "The" [1]=> string(2) "is" [2]=> string(4) "with" } } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41490&edit=1
