Help Parsing XML with PHP

[wjaram]

I need some help parsing XML with PHP. Below is a sample of the XML I'm using.

<?xml version="1.0" encoding="UTF-8"?>
<response>
	<requestinformation code="100">
		<codemessage>RECORDS FOUND</codemessage>
		<inputs>
			<firstname>test</firstname>
			<lastname>test</lastname>
			<dob year="1976" month="12" day="2"/>
			<ssn>123456789</ssn>
			<state/>
                        <addressinfo type="Current">
                            <streetnumber/>
                            <streetname/>
                            <unitnumber/>
                            <municipality/>
                            <state/>
                            <postalcode/>
			</addressinfo>
			<addressinfo type="Previous">
                            <streetnumber/>
                            <streetname/>
                            <unitnumber/>
                            <municipality/>
                            <state/>
                            <postalcode/>
			</addressinfo>
			<endusercode>ABC</endusercode>
                        <enduserstate>FL</enduserstate>
                        <reportusestate>FL</reportusestate>
                        <permissiblepurpose>00</permissiblepurpose>
                        <version>2.0</version>
                        <product>Essential Report</product>
			<quoteback/>
		</inputs>
	</requestinformation>
	<addressinformation>
		<ssn-validation>
			<message>SSN is valid.Issued in Florida</message>
			<year>Issued In Year 1959 And 1960</year>
		</ssn-validation>
		<records count="1">
			<record>
				<firstname>TEST</firstname>
				<middlename>THE</middlename>
				<lastname>CASE</lastname>
				<namesuffix>MR</namesuffix>
				<address>
					<street-number>1111</street-number>
					<street-pre-direction>N</street-pre-direction>
					<street-name>TABLE</street-name>
					<street-post-direction>NE</street-post-direction>
					<street-suffix>RD</street-suffix>
					<unit-designation>APT</unit-designation>
					<unit-number>1</unit-number>
					<city>TAMPA</city>
					<state>FL</state>
					<zip>98765</zip>
					<zip4>4321</zip4>
					<county>CITRUS</county>
				</address>
			</record>
		</records>
	</addressinformation>
	<criminalinformation></criminalinformation>
	<globalinformation></globalinformation>
</response>

I've used the folliwng PHP code successfully at getting the values from the elements inside "<requestinformation>":

$response = $doc->getElementsByTagName("response")->item(0);

$request_info = $response->getElementsByTagName("requestinformation")->item(0);
$code = $request_info->getAttributeNode("code")->value;
$codemessage = $request_info->getElementsByTagName("codemessage")->item(0)->nodeValue;
	
$inputs = $request_info->getElementsByTagName("inputs")->item(0);
$firstname = $inputs->getElementsByTagName("firstname")->item(0)->nodeValue;
$lastname = $inputs->getElementsByTagName("lastname")->item(0)->nodeValue;

But I keep on getting the error "Fatal error: Call to a member function getElementsByTagName() on a non-object in /essential.php on line 26" when I try to get information inside of "<addressinformation>":

$address_info = $response->getElementsByTagName("addressinformation")->item(0);
$ssn_validation = $address_info->getElementsByTagName("ssn-validation")->item(0);
$ssn_message = $ssn_validation->getElementsByTagName("message")->item(0)->nodeValue; //THIS IS THE LINE THAT PRODUCES THE ERROR

What am I doing wrong? Why does it work for the element "<requestinformation>" but not for "<addressinformation>"?

Apparently no reason. Maybe due to some typos in your working copy of xml/php?
