XML/Input: Difference between revisions

=={{header|OmniMark}}==

OmniMark′s pedigree was SGML processing. XML processing uses similar principles, with the OmniMark script taking two input files: first, a DTD defining the structure, and second, the XML data.

''The DTD'' — '''XML-input.dtd'''

<syntaxhighlight lang="dtd">

<!DOCTYPE Students [

<!ELEMENT Students (Student)+ >

<!ELEMENT Student (Pet)* >

<!ATTLIST Student

Name CDATA #REQUIRED

Gender CDATA #REQUIRED

DateOfBirth CDATA #REQUIRED >

<!ELEMENT Pet EMPTY >

<!ATTLIST Pet

Type CDATA #REQUIRED

Name CDATA #REQUIRED >

]></syntaxhighlight>

''The XML'' — '''XML-input.xml'''

<syntaxhighlight lang="dtd">

<Students>

<Student Name="April" Gender="F" DateOfBirth="1989-01-02" />

<Student Name="Bob" Gender="M" DateOfBirth="1990-03-04" />

<Student Name="Chad" Gender="M" DateOfBirth="1991-05-06" />

<Student Name="Dave" Gender="M" DateOfBirth="1992-07-08">

<Pet Type="dog" Name="Rover" />

</Student>

<Student DateOfBirth="1993-09-10" Gender="F" Name="&#x00C9;mily" />

</Students>

''The OmniMark script'' — '''XML-input.xom'''

<syntaxhighlight lang="omnimark">
