php - How to parse SOAP in order to list all Request and Object names -

-

i'm able parse xml soap when know namespace , request name.

because have different kind of soap requests, request name in soap file . extract of part of soap:

<?xml version="1.0" encoding="utf-8"?> <soap-env:envelope     xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/"     xmlns:ns1="http://schema.example.com"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xmlns:xsd="http://www.w3.org/2001/xmlschema"    xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/"    soap-env:encodingstyle="http://schemas.xmlsoap.org/soap/encoding/" > <soap-env:body>  **<ns1:sendmailling>**  <campagne xsi:type="ns1:campaign"><activatededup xsi:nil="true"/><billingcode     xsi:nil="true"/><deliveryfax xsi:type="ns1:deliveryfax"/>  <deliverymail xsi:type="ns1:deliverymail">  ...

php code:

if(is_file($file))     {         $content=file_get_contents($file);           $xml = simplexml_load_string($content);         $xml->registerxpathnamespace('ns1', 'http://schema.example.com');            foreach ($xml->xpath('\\soap-env:') $item)         {             //certainly bad way?             echo "<pre>";                 print_r($item);             echo "</pre>";          }          echo "<pre>";             print_r($xml);         echo "</pre>";       }

i no result... make appears : 'sendmailling' (identify request name)

when specify 

//foreach($xml->xpath('//ns1:sendmailling') $item)

there no problems.

i tried foreach($xml->xpath('//ns1') $item)
, $xml->xpath('//soap-enc'), $xml->xpath('//body') but...

i had problems understand questions not answer.

if understand right, want select element nodes direct children of <soap-env:body> , in ns1 / http://schema.example.com namespace.

you have registered namespace prefix used simplexmlelement::xpath:

$xml->registerxpathnamespace('ns1', 'http://schema.example.com');

you have not yet registered soap-env / http://schemas.xmlsoap.org/soap/envelope/ namespace far can see.

in xpath match element can specify it's namespace. there multiple ways how done:

*               elements in namespace. prefix:*        elements in namespace "prefix" (registered prefix) prefix:local    "local" elements in namespace "prefix"

for example select elements ns1 prefix:

//ns1:*

you might want limit because want direct children withn <soap-env:body> register namespace soap-env prefix , extend previous xpath:

/soap-env:body/ns1:*

this should have elements you're looking for.

(op:) again, when 

foreach ($xml->xpath('//soap-env:body/ns1:*') $item) {     echo $item->getname() . "<br>"; }

all ok request name 'sendmailling'.

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
