Hi,
When trying to XHTML-validate lesson/import.html (in the Swedish translation) I get this:
This page is not Valid XHTML 1.0 Transitional!
Below are the results of attempting to parse this document with an SGML parser.
1. Line 35, column 56: cannot generate system identifier for general entity "module"
... href="help.php?file=formatgift.html&module=quiz">Mer info om "GIFT"-formatet
An entity reference was found in the document, but there is no reference by that name defined. Often this is caused by misspelling the reference name, unencoded ampersands, or by leaving off the trailing semicolon (;). The most common cause of this error is unencoded ampersands in URLs as described by the WDG in "Ampersands in URLs".
Entity references start with an ampersand (&) and end with a semicolon (;). If you want to use a literal ampersand in your document you must encode it as "&" (even inside URLs!). Be careful to end entity references with a semicolon or your entity reference may get interpreted in connection with the following text. Also keep in mind that named entity references are case-sensitive; &Aelig; and æ are different characters.
Note that in most documents, errors related to entity references will trigger up to 5 separate messages from the Validator. Usually these will all disappear when the original problem is fixed.
2. Line 35, column 56: general entity "module" not defined and no default entity
... href="help.php?file=formatgift.html&module=quiz">Mer info om "GIFT"-formatet
This is usually a cascading error caused by a an undefined entity reference or use of an unencoded ampersand (&) in an URL or body text. See the previous message for further details.
1. Line 35, column 62: reference not terminated by REFC delimiter
..."help.php?file=formatgift.html&module=quiz">Mer info om "GIFT"-formatet</a><.
If you meant to include an entity that starts with "&", then you should terminate it with ";". Another reason for this error message is that you inadvertently created an entity by failing to escape an "&" character just before this text.
Here is the type of code that causes the validation problems:
<a href="help.php?file=formatgift.html&module=quiz">Mer info om "GIFT"-formatet</a>
What to do?
