    <p>You could use a modified version of the code below that catches the start and end of entities. It takes a few seconds to execute since the parser has to fetch the declarations of all HTML latin1 entities. When you get an entity that does not start with <code>%</code>, you could do the replacement of the inserted char in your <code>acc</code> buffer. Pay attention to predefined entities like <code>&amp;amp;</code>.</p> <p>You could also use a Sax filter to the job automatically.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
