Struct exile::PI [−][src]
Represents a Processing Instruction (PI) in an XML document.
XML Spec
https://www.w3.org/TR/2006/REC-xml11-20060816/#sec-pi [Definition: Processing instructions (PIs) allow documents to contain instructions for applications.]
Processing Instructions
[16] PI ::= '<?' PITarget (S (Char* - (Char* '?>' Char*)))? '?>'
[17] PITarget ::= Name - (('X' | 'x') ('M' | 'm') ('L' | 'l'))
PIs are not part of the document's character data, but must be passed through to the application. The PI begins with a target (PITarget) used to identify the application to which the instruction is directed. The target names "XML", "xml", and so on are reserved for standardization in this or future versions of this specification. The XML Notation mechanism may be used for formal declaration of PI targets. Parameter entity references must not be recognized within processing instructions.
Implementations
impl PI
[src]
pub fn new<S1, S2>(target: S1, data: S2) -> Result<Self, XDocErr> where
S1: Into<String> + AsRef<str>,
S2: Into<String> + AsRef<str>,
[src]
S1: Into<String> + AsRef<str>,
S2: Into<String> + AsRef<str>,
Create a new processing instruction.
pub fn target(&self) -> &String
[src]
Return the target from a processing instruction, e.g. in <?foo bar baz?>
, foo
is the
target.
pub fn data(&self) -> &String
[src]
Return the data from a processing instruction, e.g. in <?foo bar baz?>
, bar baz
is the
data.
pub fn write<W>(
&self,
writer: &mut W,
opts: &WriteOpts,
depth: usize
) -> Result<(), XDocErr> where
W: Write,
[src]
&self,
writer: &mut W,
opts: &WriteOpts,
depth: usize
) -> Result<(), XDocErr> where
W: Write,
Write the processing instruction to the Write
object.
