NAME

SQL::Translator::Producer::XML - XML output

SYNOPSIS

  use SQL::Translator::Producer::XML;

DESCRIPTION

Meant to create some sort of usable XML output.

ARGS

Takes the following optional producer_args:

emit_empty_tags

If this is set to a true value, then tags corresponding to value-less elements will be emitted. For example, take this schema:

  CREATE TABLE random (
    id int auto_increment PRIMARY KEY,
    foo varchar(255) not null default '',
    updated timestamp
  );

With emit_empty_tags = 1, this will be dumped with XML similar to:

  <table>
    <name>random</name>
    <order>1</order>
    <fields>
      <field>
        <is_auto_inc>1</is_auto_inc>
        <list></list>
        <is_primary_key>1</is_primary_key>
        <data_type>int</data_type>
        <name>id</name>
        <constraints></constraints>
        <null>1</null>
        <order>1</order>
        <size></size>
        <type>field</type>
      </field>

With emit_empty_tags = 0, you'd get:

  <table>
    <name>random</name>
    <order>1</order>
    <fields>
      <field>
        <is_auto_inc>1</is_auto_inc>
        <is_primary_key>1</is_primary_key>
        <data_type>int</data_type>
        <name>id</name>
        <null>1</null>
        <order>1</order>
        <type>field</type>
      </field>

This can lead to dramatic size savings.
