133 XML::LibXML::PI \- XML::LibXML Processing Instructions
135 .IX Header "SYNOPSIS"
138 \& # Only methods specific to Processing Instruction nodes are listed here,
139 \& # see XML::LibXML::Node manpage for other methods
141 \& $pinode\->setData( $data_string );
142 \& $pinode\->setData( name=>string_value [...] );
145 .IX Header "DESCRIPTION"
146 Processing instructions are implemented with XML::LibXML with read and write
147 access. The \s-1PI\s0 data is the \s-1PI\s0 without the \s-1PI\s0 target (as specified in \s-1XML\s0 1.0
148 [17]) as a string. This string can be accessed with getData as implemented in XML::LibXML::Node.
150 The write access is aware about the fact, that many processing instructions
151 have attribute like data. Therefore \fIsetData()\fR provides besides the \s-1DOM\s0 spec
152 conform Interface to pass a set of named parameter. So the code segment
155 \& my $pi = $dom\->createProcessingInstruction("abc");
156 \& $pi\->setData(foo=>\*(Aqbar\*(Aq, foobar=>\*(Aqfoobar\*(Aq);
157 \& $dom\->appendChild( $pi );
160 will result the following \s-1PI\s0 in the \s-1DOM:\s0
163 \& <?abc foo="bar" foobar="foobar"?>
166 Which is how it is specified in the \s-1DOM\s0 specification. This three step
167 interface creates temporary a node in perl space. This can be avoided while
168 using the \fIinsertProcessingInstruction()\fR method. Instead of the three calls
169 described above, the call
172 \& $dom\->insertProcessingInstruction("abc",\*(Aqfoo="bar" foobar="foobar"\*(Aq);
175 will have the same result as above.
177 XML::LibXML::PI's implementation of \fIsetData()\fR documented below differs a bit from the the
178 standard version as available in XML::LibXML::Node:
182 \& $pinode\->setData( $data_string );
183 \& $pinode\->setData( name=>string_value [...] );
186 This method allows to change the content data of a \s-1PI\s0. Additionally to the
187 interface specified for \s-1DOM\s0 Level2, the method provides a named parameter
188 interface to set the data. This parameter list is converted into a string
189 before it is appended to the \s-1PI\s0.
