Function Documentation

a_v()

void ghidra::a_v ( ostream &  s, const string &  attr, const string &  val  )

inline

Output an XML attribute name/value pair to stream.

Parameters

s	is the output stream
attr	is the name of the attribute
val	is the attribute value

References ghidra::a_v().

Referenced by ghidra::a_v(), ghidra::XmlEncode::writeSpace(), and ghidra::XmlEncode::writeString().

a_v_b()

void ghidra::a_v_b ( ostream &  s, const string &  attr, bool  val  )

inline

Output the given boolean value as an XML attribute.

Parameters

s	is the output stream
attr	is the name of the attribute
val	is the given boolean value

a_v_i()

void ghidra::a_v_i ( ostream &  s, const string &  attr, intb  val  )

inline

Output the given signed integer as an XML attribute value.

Parameters

s	is the output stream
attr	is the name of the attribute
val	is the given integer value

a_v_u()

void ghidra::a_v_u ( ostream &  s, const string &  attr, uintb  val  )

inline

Output the given unsigned integer as an XML attribute value.

Parameters

s	is the output stream
attr	is the name of the attribute
val	is the given unsigned integer value

xml_escape()

void ghidra::xml_escape	(	ostream &	s,
		const char *	str
	)

Send the given character array to a stream, escaping characters with special XML meaning.

This makes the following character substitutions:

• '<' => "&lt;"
• '>' => "&gt;"
• '&' => "&amp;"
• '"' => "&quot;"
• '\'' => "&apos;"

Parameters

s	is the stream to write to
str	is the given character array to escape

xml_parse()

int4 ghidra::xml_parse	(	istream &	i,
		ContentHandler *	hand,
		int4	dbg = 0
	)

Start-up the XML parser given a stream and a handler.

This runs the low-level XML parser.

Parameters

i	is the given stream to get character data from
hand	is the ContentHandler that stores or processes the XML content events
dbg	is non-zero if the parser should output debug information during its parse

Returns

0 if there is no error during parsing or a (non-zero) error condition

xml_readbool()

bool ghidra::xml_readbool ( const string &  attr )

inline

Read an XML attribute value as a boolean.

This method is intended to recognize the strings, "true", "yes", and "1" as a true value. Anything else is returned as false.

Parameters

attr	is the given XML attribute value (as a string)

Returns

either true or false

xml_tree()

Document * ghidra::xml_tree

(

istream &

i

)

Parse the given XML stream into an in-memory document.

The stream is parsed using the standard ContentHandler for producing an in-memory DOM representation of the XML document.

Parameters

i	is the given stream

Returns

the in-memory XML document
