Parser

public class XmlParser
extends AbstractParser

A parser for XML documents. Adds squiggle underlines for any XML errors found (though most XML parsers don't really have error recovery and so only can find one error at a time).

This class isn't actually used by RSyntaxTextArea anywhere, but you can install and use it yourself. Doing so is as simple as:

 XmlParser xmlParser = new XmlParser();
 textArea.addParser(xmlParser);
 

To support DTD validation, specify an entity resolver when creating the parser, and enable validation like so:

 XmlParser xmlParser = new XmlParser(new MyEntityResolver());
 xmlParser.setValidating(true);
 textArea.addParser(xmlParser);
 

Also note that a single instance of this class can be installed on multiple instances of RSyntaxTextArea.

For a more complete XML parsing/validation solution, see the RSTALanguageSupport project's XmlLanguageSupport class.

构造器详细资料

XmlParser

public XmlParser()

XmlParser

public XmlParser(org.xml.sax.EntityResolver resolver)

Constructor allowing DTD validation of documents.

参数:

resolver - An entity resolver to use if validation is enabled.

另请参阅:

setValidating(boolean)

方法详细资料

isValidating

public boolean isValidating()

Returns whether this parser does DTD validation.

返回:

Whether this parser does DTD validation.

另请参阅:

setValidating(boolean)

parse

public ParseResult parse(RSyntaxDocument doc,
                java.lang.String style)

Parses input from the specified document.

参数:

doc - The document to parse. This document is in a read lock, so it cannot be modified while parsing is occurring.

style - The language being rendered, such as SyntaxConstants.SYNTAX_STYLE_JAVA.

返回:

An object describing the section of the document parsed and the results. This is guaranteed to be non-null.

setValidating

public void setValidating(boolean validating)

Sets whether this parser will use DTD validation if required.

参数:

validating - Whether DTD validation should be enabled. If this is true, documents must specify a DOCTYPE, and you should have used the constructor specifying an entity resolver.
