parse XML Document Type Declaration (DTD) documents

dtd-text

A Haskell library which provides means to parse XML Document Type Declaration (DTD) documents. This library is meant to be used in concert with dtd-types. Itself is based around the xml-types package.

This fork initially updates some of the libraries and dependencies. The following libraries are no longer needed:

• attoparsec-text
• blaze-builder

Upper bounds on all packages, except dtd-types, has been relaxed as this seems to be a general best practice among the Haskell community moving forward. dtd-text also does not have any external library dependencies.

For more basic information please check the Project page.

hs-dtd-text's Issues

Parser stops on attribute-value or entity-value

Attribute values must be pruned as an example:

<!ELEMENT square EMPTY>
<!ATTLIST square width CDATA "0">

will fail on square width attribute for square. the following will work fine:

<!ELEMENT square EMPTY>
<!ATTLIST square width CDATA #REQUIRED>

This would force the developer to either put in a 'with default' attribute lookup or smart constructor. Not to mention that it does take the serialization format out of sync between parties.

Does not handle Internal or External DTD Declaration

Must prune !DOCTYPE element the following examples will not parse:

<?xml version="1.0"?>
<!DOCTYPE note [
<!ELEMENT note (to,from,heading,body)>
<!ELEMENT to (#PCDATA)>
<!ELEMENT from (#PCDATA)>
<!ELEMENT heading (#PCDATA)>
<!ELEMENT body (#PCDATA)>
]>

(OR)

<?xml version="1.0"?>
<!DOCTYPE note SYSTEM "note.dtd">
