The <code>get</code> function can read markup into a native datastructure, which can be analysed using pattern matching.
Read input from file:▼
The read datastructure is a flat list of tags and text fragments. For proper nesting of elements extra code would have to be written, but in this simple task that is not necessary. On the downside, the pattern must both handle empty tags (the <code>(? (Name.?name) ?,</code> pattern) and open tags (the <code>? (Name.?name) ?</code> pattern).
<lang bracmat>( :?names
