Detailed Description

Stores the current state of XMLParser during parsing.

Used to add parse warnings and store global state like the parsing options.

Constructor & Destructor Documentation

XMLParserContext()

donner::svg::parser::XMLParserContext::XMLParserContext ( std::string_view input, std::vector< ParseError > * warningsStorage, const XMLParser::Options & options )

inline

Construct a new context for the given input string.

Parameters

input	Input string.
warningsStorage	Storage for warnings, may be nullptr to disable warnings.
options	Options for parsing.

Member Function Documentation

addSubparserWarning()

void donner::svg::parser::XMLParserContext::addSubparserWarning ( ParseError && warning, ParserOrigin origin )

inline

Add a warning from a subparser to the list of warnings, remapping the error back to the original input string.

Parameters

warning	Warning to add.
origin	Origin of the subparser.

addWarning()

void donner::svg::parser::XMLParserContext::addWarning ( ParseError && warning )

inline

Add a warning to the list of warnings.

Parameters

warning

Warning to add.

fromSubparser()

ParseError donner::svg::parser::XMLParserContext::fromSubparser ( ParseError && error, ParserOrigin origin )

inline

Remap a parse error from a subparser back to the original input string, translating the line numbers.

Parameters

error	Error to remap.
origin	Origin of the subparser.

Returns

ParseError Remapped error.

lineOffset()

size_t donner::svg::parser::XMLParserContext::lineOffset ( size_t line ) const

inline

Returns the offset of a given 1-indexed line number.

Parameters

line	Line number, 1-indexed.

offsetToLine()

size_t donner::svg::parser::XMLParserContext::offsetToLine ( size_t offset ) const

inline

Return line numbers for the given offset.

For example, given a string: "abc\n123", offsets 0-3 would be considered line 1, and offsets after 4 (corresponding to the index of '1'), would be line 2. Values beyond the length of the string return the last line number.

Parameters

offset

Character index.

Returns

size_t Line number, 1-indexed.

parserOriginFrom()

ParserOrigin donner::svg::parser::XMLParserContext::parserOriginFrom ( std::string_view substring ) const

inline

Create a ParserOrigin for the given substring, where substring is within the XML parser's original string, input_.

Parameters

substring

Substring within the XML parser's original string.

setNamespacePrefix()

void donner::svg::parser::XMLParserContext::setNamespacePrefix ( std::string_view namespacePrefix )

inline

Set the XML document's default namespace prefix, such as "http://www.w3.org/2000/svg".

Parameters

namespacePrefix

The default namespace prefix, such as "http://www.w3.org/2000/svg".
