SearchEngine: HTML Parser Syntax Errors

Process Engineer Toolkit > User's Guide > Tools Reference > Search Engine > HTML Parser Syntax Errors

Unknown tag <tag>: The parser does not reorganize the tag.
<!doctype> cannot be redefined: The document type statement appears more than once in the file.
<!doctype> must appear before <html>: The document type statement must appear before any text or HTML markup.
</tag> does not exist: The tag does not have a closing tag, for example </br>.
<tag> is not currently open: The closing tag is not matched by a previous opening tag.
<tag> adding missing <missingtag>: A required container tag was not found, but was inserted by the parser.
ignoring <tag>, no enclosing <enclosingtag>: An orphan tag was encountered, which cannot be corrected, such as <param> without an enclosing <applet> tag.
<tag> has already been closed: The definition tag (such as <head>) was previously closed, possibly as the result of another tag, such as <body>.
<tag> is already defined: The definition tag (such as <head>) has already been defined.
<tag> cannot be placed after <other tag>: The tag, for example <head> is placed out of order, after the <body> tag in this case.
not an HTML file (no <html>, <head>, <title> or <body> before #PCDATA): The parser does not recognize the text file as being HTML. The file will still be read, and all words parsed. The words will be added to the body list.
expecting '>' after SGML markup: The > character is missing from the end of a SGML markup tag.
expecting '-->' to end SGML comment: The SGML comment is not correctly terminated, for example <!-- comment >
incorrect SGML comment syntax: The SGML comment is incorrectly tagged; for example <! comment -->
expecting '>' after markup name: The HTML markup tag was not correctly terminated, for example <samp
missing attribute name before '=': No name was found before the '=' character.
ignoring redefinition of attribute 'attr': The tag attribute is defined more than once.
expecting attribute name: The attribute name was not found after the tag name.
expecting attribute value: The attribute value was not found after the '=' character.
attribute value must be quoted: The attribute value contains characters which must be enclosed in quotes. Only letters, numbers, the '.' and '_' characters can appear without quotes.
unterminated literal: The attribute value has no terminating quote, for example "java.html.
empty literal: The quotes attribute value contains no characters; "".
expecting '>' after end markup name: The HTML end markup tag was not correctly terminated, for example </samp.
numeric entity exceeds 65535: The numeric entity &#number; is larger than the largest Unicode character.
expecting ';' after numeric entity: The numeric entity is missing the ';' terminator.
'ampent' is not a valid ampersand entity: The ampersand entity is unknown. The current list of ampersand entities is given in the appendix Ampersand entities. This error could be due to a missing ';' terminator such as R&ampD.
expecting ';' after ampersand entity: The ampersand entity is missing the ';' terminator.
Ill formed URL escape: The escaped URL character is not a two hexadecimal character sequence. A correct sequence is, for example, %7e or %7E for the tilde character '~'.
reserved URL characters must be escaped: The character must be converted into an URL escape sequence.
missing schema before ':': The URL has no schema (http, ftp, mailto etc) before the schema delimiter character ':'.
missing <tag> before <othertag>: A required container tag was not found, for example a <li> tag before text within a <ul> tag.
<tag> cannot be contained by <containertag>: The tag cannot appear within the container tag, and cannot be corrected by the parser. The tag is ignored.
<tag> must contain at least one element: The container tag is empty, (has no elements), when the HTML 3.2 DTD defines the tag as requiring one or more elements.
assuming <endtag> closes <tag>: The parser is correcting for a tag mismatch, such as <h1> ...</h2>.
<tag> cannot be used in <containertag>: The tag cannot appear within the container tag. The parser corrects by closing the <container-tag>.
missing <tag>: An obligatory tag such as <title> was not found in the HTML file.
missing <body> or <frameset>: The HTML file contains no displayable text.
warning: uses deprecated tags: Deprecated tags were found in the HTML document.
warning: uses extensions to the HTML 3.2 DTD: Browser specific extensions were found in the HTML document.
warning: has unknown tags: Unknown tags were found in the HTML document.
expecting </endtag> before <tag>: An obligatory end tag was not found, such as the </title> tag before a <body> tag.
expecting </endtag> before end-of-file: An obligatory end tag was not found when the end of file was reached.
warning: missing <!doctype> declaration: HTML DTD 3.2 compliant documents require a <!doctype ... > statement.
