Parse error messages

Back to Contents

These are the various messages, given during importing an external document. They all mean that the document is not well-formed.

1. "Doctype declaration not valid at line line_no, position position_no !"

   This error is given when there is a DTD in the file, containing the document and the DTD can not be parsed successfully.

2. "Invalid character at line line_no, position position_no !"

   This is given when there are characters other than white space characters at the beginning of the document.
   Example:

   Asdfg <books>…..</books>

3. "No document or wrong char encoding!"

   This is given on a blank document file or when the character encoding is not recognized. Character encoding is set when the user is asked to point out to a file containing the document.

4. "CDATA section not closed at line line_no, position position_no !"

   This is given when a CDATA element misses its closing declaration - ‘]]>’.
   Example:

   <book><![CDATA[ Alice in wonderland</book>

5. "Processing Instruction at line line_no, position position_no not closed!"

   This is given when a Processing Instruction is opened but not closed. The missing end is '?>'. Processing instructions are parsed, but not processed further.

6. "Comment at line line_no, position position_no not closed!"

   This is given when a comment is opened but not closed. The missing end is '-->'. Comments are parsed, but not processed further.

7. "Invalid element at line line_no, position position_no - <> !"

   This is given when the parser finds an opening tag without a name, that is, the sequence ‘<>’.

8. "Invalid element at line line_no, position position_no - </> !"

   This is given when the parser finds a closing tag without a name, that is, the sequence ‘</>’.

9. "Element not closed at line line_no, position position_no !"

   This is given when an opening or closing tag is not properly closed.
   Example:

   <book author = "Luis Carol>… (missing closing ")

   <book (end of document)

10. "Invalid attribute at line line_no, position position_no !"

    This is given when an attribute is not given a value.
    Example:

    <book author>

11. "Attribute value not closed at line line_no, position position_no !"

    This is given when an attribute value is not closed.
    Example:

    <book author = ”Luis Carol>

12. "Attribute declaration must be in the opening tag at line line_no, position position_no !"

    This is given when the parser finds attribute declarations in the closing tag of an element.
    Example:

    <book>Alice in Wonderland</book author = ”Luis Carol”>

13. "Invalid nesting of opening and closing tags at line line_no, position position_no.
    Expected <element> opened at line line_no, position position_no ."

    This is given when the parser finds an element that is closed before all of its children are closed.
    Example:

    <books><book> Alice in Wonderland </books>

14. "Attribute <attr_name> already declared at line line_no, position position_no !"

    Is is given when an attribute is declared more than once for the same element.
    Example:

    <book author = ”Luis” author = ”Carol”>

15. "Text not closed at line line_no, position position_no !"

    Is is given when the documents end with a text.
    Example:

    <book>Alice in Wonderland (end of document)
