Class Format

  • All Implemented Interfaces:
    java.lang.Cloneable

    public class Format
    extends java.lang.Object
    implements java.lang.Cloneable
    Class to encapsulate XMLOutputter format options. Typical users can use the standard format configurations obtained by getRawFormat() (no whitespace changes), getPrettyFormat() (whitespace beautification), and getCompactFormat() (whitespace normalization).

    Several modes are available to effect the way textual content is printed. See the documentation for Format.TextMode for details.

      • getRawFormat

        public static Format getRawFormat()
        Returns a new Format object that performs no whitespace changes, uses the UTF-8 encoding, doesn't expand empty elements, includes the declaration and encoding, and uses the default entity escape strategy. Tweaks can be made to the returned Format instance without affecting other instances.
        Returns:
        a Format with no whitespace changes
      • getPrettyFormat

        public static Format getPrettyFormat()
        Returns a new Format object that performs whitespace beautification with 2-space indents, uses the UTF-8 encoding, doesn't expand empty elements, includes the declaration and encoding, and uses the default entity escape strategy. Tweaks can be made to the returned Format instance without affecting other instances.
        Returns:
        a Format with whitespace beautification
      • getCompactFormat

        public static Format getCompactFormat()
        Returns a new Format object that performs whitespace normalization, uses the UTF-8 encoding, doesn't expand empty elements, includes the declaration and encoding, and uses the default entity escape strategy. Tweaks can be made to the returned Format instance without affecting other instances.
        Returns:
        a Format with whitespace normalization
      • setEscapeStrategy

        public Format setEscapeStrategy​(EscapeStrategy strategy)
        Sets the EscapeStrategy to use for character escaping.
        Parameters:
        strategy - the EscapeStrategy to use
        Returns:
        a pointer to this Format for chaining
      • getEscapeStrategy

        public EscapeStrategy getEscapeStrategy()
        Returns the current escape strategy
        Returns:
        the current escape strategy
      • setLineSeparator

        public Format setLineSeparator​(java.lang.String separator)
        This will set the newline separator (lineSeparator). The default is \r\n. To make it output the system default line ending string, call setLineSeparator(System.getProperty("line.separator")).

        To output "UNIX-style" documents, call setLineSeparator("\n"). To output "Mac-style" documents, call setLineSeparator("\r"). DOS-style documents use CR-LF ("\r\n"), which is the default.

        Note that this only applies to newlines generated by the outputter. If you parse an XML document that contains newlines embedded inside a text node, and you do not set TextMode.NORMALIZE, then the newlines will be output verbatim, as "\n" which is how parsers normalize them.

        If the format's "indent" property is null (as is the default for the Raw and Compact formats), then this value only effects the newlines written after the declaration and doctype.

        Parameters:
        separator - String line separator to use.
        Returns:
        a pointer to this Format for chaining

        setTextMode(org.jdom.output.Format.TextMode)
      • getLineSeparator

        public java.lang.String getLineSeparator()

      • setOmitEncoding

        public Format setOmitEncoding​(boolean omitEncoding)
        This will set whether the XML declaration (<?xml version="1.0" encoding="UTF-8"?>) includes the encoding of the document. It is common to omit this in uses such as WML and other wireless device protocols.
        Parameters:
        omitEncoding - boolean indicating whether or not the XML declaration should indicate the document encoding.
        Returns:
        a pointer to this Format for chaining
      • getOmitEncoding

        public boolean getOmitEncoding()
        Returns whether the XML declaration encoding will be omitted.
        Returns:
        whether the XML declaration encoding will be omitted
      • setOmitDeclaration

        public Format setOmitDeclaration​(boolean omitDeclaration)
        This will set whether the XML declaration (<?xml version="1.0"?gt;) will be omitted or not. It is common to omit this in uses such as SOAP and XML-RPC calls.
        Parameters:
        omitDeclaration - boolean indicating whether or not the XML declaration should be omitted.
        Returns:
        a pointer to this Format for chaining
      • getOmitDeclaration

        public boolean getOmitDeclaration()
        Returns whether the XML declaration will be omitted.
        Returns:
        whether the XML declaration will be omitted
      • setExpandEmptyElements

        public Format setExpandEmptyElements​(boolean expandEmptyElements)
        This will set whether empty elements are expanded from <tagName/> to <tagName></tagName>.
        Parameters:
        expandEmptyElements - boolean indicating whether or not empty elements should be expanded.
        Returns:
        a pointer to this Format for chaining
      • getExpandEmptyElements

        public boolean getExpandEmptyElements()
        Returns whether empty elements are expanded.
        Returns:
        whether empty elements are expanded
      • setIgnoreTrAXEscapingPIs

        public void setIgnoreTrAXEscapingPIs​(boolean ignoreTrAXEscapingPIs)
        This will set whether JAXP TrAX processing instructions for disabling/enabling output escaping are ignored. Disabling output escaping allows using XML text as element content and outputing it verbatim, i.e. as element children would be.

        When processed, these processing instructions are removed from the generated XML text and control whether the element text content is output verbatim or with escaping of the pre-defined entities in XML 1.0. The text to be output verbatim shall be surrounded by the <?javax.xml.transform.disable-output-escaping ?> and <?javax.xml.transform.enable-output-escaping ?> PIs.

        When ignored, the processing instructions are present in the generated XML text and the pre-defined entities in XML 1.0 are escaped.

        Default: false.

        Parameters:
        ignoreTrAXEscapingPIs - boolean indicating whether or not TrAX ouput escaping PIs are ignored.
        See Also:
        Result.PI_ENABLE_OUTPUT_ESCAPING, Result.PI_DISABLE_OUTPUT_ESCAPING
      • getIgnoreTrAXEscapingPIs

        public boolean getIgnoreTrAXEscapingPIs()
        Returns whether JAXP TrAX processing instructions for disabling/enabling output escaping are ignored.
        Returns:
        whether or not TrAX ouput escaping PIs are ignored.
      • getTextMode

        public Format.TextMode getTextMode()
        Returns the current text output style.
        Returns:
        the current text output style
      • setIndent

        public Format setIndent​(java.lang.String indent)
        This will set the indent String to use; this is usually a String of empty spaces. If you pass the empty string (""), then no indentation will happen but newlines will still be generated. Passing null will result in no indentation and no newlines generated. Default: none (null)
        Parameters:
        indent - String to use for indentation.
        Returns:
        a pointer to this Format for chaining
