使用php验证xsd的xml文件

Question

如何针对xsd验证xml文件？有domdocument :: schemaValidate()但它没有告诉错误在哪里.那有什么课吗？它是否有任何值得从头开始的解析器？还是只是重新发明轮子,

Answer 1

此代码执行业务:

$xml= new DOMDocument();
$xml->loadXML(<A string goes here containing the XML data>, LIBXML_NOBLANKS); // Or load if filename required
if (!$xml->schemaValidate(<file name for the XSD file>)) // Or schemaValidateSource if string used.
{
   // You have an error in the XML file
}

请参阅http://php.net/manual/en/domdocument.schemavalidate.php中的代码以检索错误.

它就像一个魅力!

有关DOMDocument :: schemaValidate的更详细反馈,请禁用libxml错误并自行获取错误信息.有关详细信息,请参阅 http://php.net/manual/en/ref.libxml.php.

的example.xml

<?xml version="1.0"?>
<example>
    <child_string>This is an example.</child_string>
    <child_integer>Error condition.</child_integer>
</example>

example.xsd

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
    <xs:element name="example">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="child_string" type="xs:string"/>
                <xs:element name="child_integer" type="xs:integer"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>

PHP

<?php

function libxml_display_error($error)
{
    $return = "<br/>\n";
    switch ($error->level) {
        case LIBXML_ERR_WARNING:
            $return .= "<b>Warning $error->code</b>: ";
            break;
        case LIBXML_ERR_ERROR:
            $return .= "<b>Error $error->code</b>: ";
            break;
        case LIBXML_ERR_FATAL:
            $return .= "<b>Fatal Error $error->code</b>: ";
            break;
    }
    $return .= trim($error->message);
    if ($error->file) {
        $return .=    " in <b>$error->file</b>";
    }
    $return .= " on line <b>$error->line</b>\n";

    return $return;
}

function libxml_display_errors() {
    $errors = libxml_get_errors();
    foreach ($errors as $error) {
        print libxml_display_error($error);
    }
    libxml_clear_errors();
}

// Enable user error handling
libxml_use_internal_errors(true);

$xml = new DOMDocument();
$xml->load('example.xml');

if (!$xml->schemaValidate('example.xsd')) {
    print '<b>DOMDocument::schemaValidate() Generated Errors!</b>';
    libxml_display_errors();
}
