Soothsilver PHP DTD Parser

This is a DTD parser contained a single PHP file that aims to be compliant to the full XML specification. The traditional method of reading XML files in PHP is to use the built-in functions based on libxml2. However, these do not allow you to read and parse Document Type Definition (DTD) files, they only tell you if the DTD is well-formed or not.

With this library, you can parse a DTD file and extract from it general and parameter entities, notations, element definitions and their attribute definitions and also processing instructions.

Examples

Print all declared entities

<?php
$dtd = \Soothsilver\DtdParser\DTD::parseText(file_get_contents("mydtd.dtd"));
foreach($dtd->generalEntities as $entity)
{
 echo $entity->Name . ": " . $entity->replacementText . "\n";
}
foreach($dtd->parameterEntities as $entity)
{
 echo $entity->Name . ": " . $entity->replacementText . "\n";
}
