Overall structure of XML file
This page is currently under development
The file is enclosed by tags as follows.
<?xml version=1.0?> <quiz> . . . </quiz>
Within the <quiz> tags are any number of <question> tags. One of these <question> tags can be a dummy question with a category type to specify a category for the import/export.
The file must be encoded in UTF8
Tags common to all question types
A question is written as follows.
<question type="multichoice|truefalse|shortanswer|match|cloze|essay|numerical|description" <questiontext format="html"> <text>What is the answer to this question?</text> </questiontext> . . . </question>
"Format" selects the Formatting options for the question text. The options are moodle_auto_format (the default), html, plain_text and markdown. The choice effects the way in which the text will be displayed.
Further tags, which usually include at least one <answer> tag, follow in the space marked with dots as child nodes to the <question> tag. The response-related tags are listed further down on this page. Various (optional?) tags are possible.

An interesting tag is the <image> tag which allows a base64-encoded image to be included.
Points for clarification:
- Exactly how does the <image> tag work?
- Is there an <image_base64> tag? How does this relate?
Multiple choice
MC questions have one <answer> tag for each choice. Each choice can carry feedback and score weighting (presumably by using the fraction attribute). In addition, an MC question has the following tags:
- single (values: true/false)
- shuffleanswers (values: 1/0)
- correctfeedback
- partiallycorrectfeedback
- incorrectfeedback
The <single> tag is used to distinguish single response (radio button) and multiple response (checkbox) variants.
<question type=multichoice> <answer fraction=100> <text>The correct answer</text> <feedback><text>Correct!</text></feedback> </answer> <answer fraction=0> <text>A distractor</text> <feedback><text>Ooops!</text></feedback> </answer> <answer fraction=0> <text>Another distractor</text> <feedback><text>Ooops!</text></feedback> </answer> <shuffleanswers>1</shuffleanswers> <single>true</single>
True/false
Two answer tags are given, one which is true, and one which is false. The fraction attribute of the answer tag presumably identifies which option is correct (100) and which is false (0). Feedback is supported. The following example shows the format when true is the correct answer and false is wrong.
<question type=truefalse> <answer fraction=100> <text>true</text> <feedback><text>Correct!</text></feedback> </answer> <answer fraction=0> <text>false</text> <feedback><text>Ooops!</text></feedback> </answer>
Short answer
The short answer question type supports alternative correct responses, each with its own weighting and feedback. The Moodle XML format uses one <answer> tag for each of the alternative correct answers.
The <usecase> tag toggles case-sensitivity with the values 1/0.
<question type=shortanswer> <answer fraction=100> <text>The correct answer</text> <feedback><text>Correct!</text></feedback> </answer>
<question type=shortanswer> <answer fraction=100> <text>The correct answer</text> <feedback><text>Correct!</text></feedback> </answer> <answer fraction=100> <text>An alternative answer</text> <feedback><text>Correct!</text></feedback> </answer>
Numerical response
The following is a simplified version of the Moodle XML format for numerical responses.
<question type=numerical> <answer> A number <fraction>100</fraction> <feedback><text>Feedback</text></feedback> </answer>
Moodle also supports a <tolerance> tag (how accurate must the number be?) and one or more <unit> tags. Unit tags have names and multipliers. E.g. if the main answer is in kilometres, an additional answer could be the equivalent in metres with a multiplier of 1000.
Matching
Pair matching responses use the <shuffleanswers> tag to determine whether the order of the items should be randomized. Each pair is contained inside a <subquestion> tag. The first item of each pair is contained with a <text> tag, while the second has an <answer> tag around it as well. Feedback and score weighting is not supported by Moodle for this response type.
<question type=match> <subquestion> <text>This is the 1st item in the 1st pair.</text> <answer> <text>This is the 2nd item in the 1st pair.</text> </answer> </subquestion> <subquestion> <text>This is the 1st item in the 2nd pair.</text> <answer> <text>This is the 2nd item in the 2nd pair.</text> </answer> </subquestion> <shuffleanswers>true</shuffleanswers>
Other question types
Cloze
It is supported, and depends on a special format for the <questiontext> tag.
Essay response type
Regular expression response type
The format appears to be identical to short answers / typed responses. Clarification about the differences is needed.
Description response type
This response type appears to have no further tags other than those contained in the question header (such as <questiontext>).
Random matching
Moodle has a question type which consists of taking short answer questions in the same quiz and displaying them as a pair matching exercise. However Moodle is neither able to export nor import this question type.
