# XML::DOM::ProcessingInstruction(3pm)

An XML processing instruction in XML::DOM

## NAME

XML::DOM::ProcessingInstruction - An XML processing instruction in XML::DOM

## DESCRIPTION

XML::DOM::ProcessingInstruction extends XML::DOM::Node.

It represents a "processing instruction", used in XML as a way to keep  processor-specific information in the text of the document. An example:

```
 <?PI processing instruction?>
```

Here, "PI" is the target and "processing instruction" is the data.

### METHODS

- getTarget

  The target of this processing instruction. XML defines this as being the first token following the markup that begins the processing instruction.

- getData and setData (data)

  The content of this processing instruction. This is from the first non white space character after the target to the character immediately preceding the ?\>.
