XML Validation against XSD in PHP libxml

domdocument, libxml2, php, xml, xsd

Solution

dom specially gives two functions to validate with schema. One is to give file path

$doc = new DOMDocument();
$doc->load('PATH TO XML');

$is_valid_xml = $doc->schemaValidate('PATH TO XSD');

or else you could use

$is_valid_xml = $doc->schemaValidateSource($source)

This source should be a string containing the schema. It seems that you are using schemaValidateSource function other than schemaValidate. (Once I was stuck in the same place) cheers

Problem

I have created an xml like below ``` <Request> <RequestType>Logon</RequestType> <MobileId>23424</MobileId> <Password>123456Gg</Password> </Request> ``` and my xsd file is like below code ``` <?xml version="1.0" encoding="utf-8"?> <xsd:schema attributeFormDefault="unqualified" elementFormDefault="qualified" version="1.0" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:element name="Request" type="RequestType"/> <xsd:complexType name="RequestType"> <xsd:sequence> <xsd:element name="RequestType"> <xsd:simpleType> <xsd:restriction base="xsd:string"> <xsd:enumeration value="Logon"/> </xsd:restriction> </xsd:simpleType> </xsd:element> <xsd:element name="MobileId" > <xsd:simpleType> <xsd:restriction base="xsd:string"> <xsd:minLength value="0" /> <xsd:maxLength value="10" /> </xsd:restriction> </xsd:simpleType> </xsd:element> <xsd:element name="Password"> <xsd:simpleType> <xsd:restriction base="xsd:string"> <xsd:minLength value="0"/> <xsd:maxLength value="255"/> </xsd:restriction> </xsd:simpleType> </xsd:element> </xsd:sequence> </xsd:complexType> </xsd:schema> ``` I have used PHP'S DOMDocument's schemaValidate function to validate the xml against the xsd, and it gives following error ``` Fatal Error 4: Start tag expected, '<' not found on line 5 Error 1872: The document has no document element. on line 0 ``` But I have tested those two files (xml and xsd) in this link W3C XML Schema Online validation, and it successfully validates without showing any error. What I have to do to get work this in php? Note: my php libxml version is 2.7.8
