#[repr(transparent)]
pub struct MarkupParseContext { /* private fields */ }
Expand description

A parse context is used to parse a stream of bytes that you expect to contain marked-up text.

See g_markup_parse_context_new(), GMarkupParser, and so on for more details.

Implementations

Signals to the MarkupParseContext that all data has been fed into the parse context with parse().

This function reports an error if the document isn’t complete, for example if elements are still open.

Returns

true on success, false if an error was set

Retrieves the name of the currently open element.

If called from the start_element or end_element handlers this will give the element_name as passed to those functions. For the parent elements, see g_markup_parse_context_get_element_stack().

Returns

the name of the currently open element, or None

Retrieves the current line number and the number of the character on that line. Intended for use in error messages; there are no strict semantics for what constitutes the “current” line number other than “the best number we could come up with for error messages.”

Returns
line_number

return location for a line number, or None

char_number

return location for a char-on-line number, or None

Feed some data to the MarkupParseContext.

The data need not be valid UTF-8; an error will be signaled if it’s invalid. The data need not be an entire document; you can feed a document into the parser incrementally, via multiple calls to this function. Typically, as you receive data from a network connection or file, you feed each received chunk of data into this function, aborting the process if an error occurs. Once an error is reported, no further data may be fed to the MarkupParseContext; all errors are fatal.

text

chunk of text to parse

text_len

length of text in bytes

Returns

false if an error occurred, true on success
