Parsing string into XMLReader in PHP5

Problem: How to parse string result into XML parser in PHP5
Solution: Use one of several PHP5 extensions such as XMLReader

$reader = new XMLReader();
$reader->XML($resultInString);

Below is the sample code that calls PTT Web Services and extracting only the price of GASOHOL

<?php

$wsdl = 'http://www.pttplc.com/pttinfo.asmx?WSDL';

$client = new SoapClient($wsdl);
//array('proxy_host' => "202.12.97.116",
//'proxy_port' => 8088));


$methodName = 'CurrentOilPrice';

$params = array('Language'=>'EN');

$soapAction = 'http://www.pttplc.com/ptt_webservice/CurrentOilPrice';

$objectResult = $client->__soapCall($methodName,
array('parameters' => $params), array('soapaction' => $soapAction));


// echo $objectResult->CurrentOilPriceResult;
$result = $objectResult->CurrentOilPriceResult;
$reader = new XMLReader();
$reader->XML($result);
$found = false;
while ($reader->read()) {
$tagName = $reader->name;
$reader->read();
$tagValue = $reader->value;
if ($tagName == "PRODUCT" &&
$tagValue == "GASOHOL") {
$found = true;
}
if ($found == true && $tagName == "PRICE") {
$price = $reader->value;
break;
}
}
echo "GASOHOL price is $price";
$reader->close();
?>


Then, you should get the result as shown in the below picture.

How to Change soap:address when Using NetBeans 5.5

Problem:
In developing web service with netbeans and use Sun application server, how to change soap address location
from
uri =http://100.22.111.111:8081/testws/testService?wsdl
to
soap:address location="http://111.222.33.444:8081/testws/testService"

Solution:

1. Go to directory {local glassfish instance}/domains/domain1/config such as C:\Sun\AppServer\domains\domain1\config

2 modify file domains.xml by modifying element http-listener

from

<http-listener acceptor-threads="1" address="0.0.0.0" blocking-enabled="false" default-virtual-server="server" enabled="true" family="inet" id="http-listener-1" port="8080" security-enabled="false" server-name="" xpowered-by="true">

to

<http-listener acceptor-threads="1" address="0.0.0.0" blocking-enabled="false" default-virtual-server="server" enabled="true" family="inet" id="http-listener-1" port="8081"server-name="111.22.33.444" security-enabled="false" xpowered-by="true">

3. Restart Sun Application Server

4. Deploy Web service and view its WSDL

Now we have soap:address change to 111.22.33.444:8081 as we wish.
