A list of all possible errors.

Variants§

§

InvalidXmlPrefixUri(TextPos)

The xmlns:xml attribute must have an http://www.w3.org/XML/1998/namespace URI.

§

UnexpectedXmlUri(TextPos)

Only the xmlns:xml attribute can have the http://www.w3.org/XML/1998/namespace URI.

§

UnexpectedXmlnsUri(TextPos)

The http://www.w3.org/2000/xmlns/ URI must not be declared.

§

InvalidElementNamePrefix(TextPos)

xmlns can’t be used as an element prefix.

§

DuplicatedNamespace(String, TextPos)

A namespace was already defined on this element.

§

UnknownNamespace(String, TextPos)

An unknown namespace.

Indicates that an element or an attribute has an unknown qualified name prefix.

The first value is a prefix.

§

UnexpectedCloseTag

Incorrect tree structure.

Fields

§expected: String
§actual: String
§

UnexpectedEntityCloseTag(TextPos)

Entity value starts with a close tag.

Example:

<!DOCTYPE test [ <!ENTITY p '</p>'> ]>
<root>&p;</root>
§

UnknownEntityReference(String, TextPos)

A reference to an entity that was not defined in the DTD.

§

MalformedEntityReference(TextPos)

A malformed entity reference.

A & character inside an attribute value or text indicates an entity reference. Otherwise, the document is not well-formed.

§

EntityReferenceLoop(TextPos)

A possible entity reference loop.

The current depth limit is 10. The max number of references per reference is 255.

§

InvalidAttributeValue(TextPos)

Attribute value cannot have a < character.

§

DuplicatedAttribute(String, TextPos)

An element has a duplicated attributes.

This also includes namespaces resolving. So an element like this will lead to an error.

<e xmlns:n1='http://www.w3.org' xmlns:n2='http://www.w3.org' n1:a='b1' n2:a='b2'/>
§

NoRootNode

The XML document must have at least one element.

§

UnclosedRootNode

The root node was opened but never closed.

§

DtdDetected

An XML with DTD detected.

This error will be emitted only when ParsingOptions::allow_dtd is set to false.

§

NodesLimitReached

Indicates that the ParsingOptions::nodes_limit was reached.

§

AttributesLimitReached

Indicates that too many attributes were parsed.

§

NamespacesLimitReached

Indicates that too many namespaces were parsed.

§

ParserError(Error)

Errors detected by the xmlparser crate.
