InDesign CS5 And XML Validation

In purchase for XML documents to be trusted by all parties utilizing those to share info, it’s significant that the integrity of the document is gauged in some way: this really is the task of validation. In purchase to be trusted, an XML document should pass 2 tests: it need to be well-formed and it should be valid. A well-formed document is 1 which refuses to break some of the fundamental syntactical rules to which every XML document should adhere. A valid XML document is 1 which, in addition to being well-formed, adheres to a certain set of rules laid down for that kind of XML document.

For an XML document to be considered well-formed, it should meet certain criteria. Element and feature names need to be legal in XML. Names cannot contain spaces. Names cannot begin with a quantity or specialized character. Names cannot commence with all the letters “xml”-in any case combination. Names should contain at smallest 1 character. Element tags should be correctly nested. If tag2 is opened after tag1 then tag2 should be shut before tag1 closes: overlapping element tags are not permitted.

You markup should provide a closing tag to match each starting tag. In the older days, internet browsers were very forgiving when closing HTML tags were omitted, as well as the document might nevertheless be displayed: not thus with XML. This tip furthermore applies to clear ingredients (those that contain no text or different elements). But, there is a unique structure for indicating clear ingredients which combines the starting and closing tags to shape a single tag.

All characteristics need values. So, in XHTML, (which indicates a pre-selected, standard item in a drop-down menu, on a form) today has to be written: way chosen = “selected”. There can be an supposition that numerical values never want quotes, because is the case in other environments; in XML quotes are obligatory for all values. Single or double quotes are permitted.

There are five principal characters which is mistaken for XML markup: each of these should be changed with character entities. InDesign’s built-in validator checks an XML document for well-formedness before importing and usually display a helpful mistake content if it finds illegal markup. Importantly, the mistake content might include the line quantity of the issue code.
