Functions 12

fnXmlDetectedEncoding encodingFromName(string name) @safeMaps an encoding name to `XmlDetectedEncoding`.

fnstring tryParseXmlEncodingDeclarationAscii(const(ubyte)[] bytes) @safeAttempts to parse the XML declaration `encoding='...'` pseudo-attribute from raw bytes.

fnXmlDetectedEncoding encodingFromLabel(string label, out bool supported) @safeMaps a declared encoding label to an internal decoding choice.

fnXmlVersion parseXmlVersion(string versionString) @safe pure nothrowParses an XML version string.

fnbool isValidXmlChar(dchar c, XmlVersion xmlVersion = XmlVersion.XML_1_0) @safe pure nothrowReturns `true` if `c` is a valid XML character.

fnsize_t utf8BomLength(const(ubyte)[] bytes) @safe pure nothrowReturns the length of a UTF-8 BOM prefix in `bytes`.

fnXmlDetectedEncoding detectEncoding(const(ubyte)[] bytes) @safe pure nothrowDetects the encoding of `bytes`.

fnstring decodeToUtf8(const(ubyte)[] bytes, XmlDetectedEncoding encoding) @safeDecodes `bytes` into a UTF-8 `string` using the detected encoding.

private fnvoid appendUtf8CodePoint(ref typeof(appender!string()) sink, uint cp) @safe

fnbool isValidUtf8(const(ubyte)[] bytes) @safe pure nothrowValidates that `bytes` is well-formed UTF-8.

fnstring normalizeNewlines(string input)Normalizes XML newlines.

fnstring normalizeAttributeValue(string value) @safeNormalizes an XML attribute value.
