        public java.lang.String getLineSeparator()
      • setLineSeparator

        public void setLineSeparator​(java.lang.String separator)

        public boolean isOmitEncoding()
      • setOmitEncoding

        public void 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 suppress this in protocols such as WML and SOAP.

      • setSuppressDeclaration

        public void setSuppressDeclaration​(boolean suppressDeclaration)

        Parameters:
        suppressDeclaration - boolean indicating whether or not the XML declaration should be suppressed.
      • isSuppressDeclaration

        public boolean isSuppressDeclaration()
        DOCUMENT ME!
        Returns:
        true if the output of the XML declaration (<?xml version="1.0"?>) should be suppressed else false.
      • setNewLineAfterDeclaration

        public void setNewLineAfterDeclaration​(boolean newLineAfterDeclaration)

        This will set whether a new line is printed after the XML declaration (assuming it is not supressed.)

        Parameters:
        newLineAfterDeclaration - boolean indicating whether or not to print new line following the XML declaration. The default is true.
      • isNewLineAfterDeclaration

        public boolean isNewLineAfterDeclaration()
        DOCUMENT ME!
        Returns:
        true if a new line should be printed following XML declaration
      • isExpandEmptyElements

        public boolean isExpandEmptyElements()
      • setExpandEmptyElements

        public void 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.
      • isTrimText

        public boolean isTrimText()
      • setTrimText

        public void setTrimText​(boolean trimText)
        This will set whether the text is output verbatim (false) or with whitespace stripped as per Element.getTextTrim(). Default: false
        Parameters:
        trimText - boolean true → trim the whitespace, false → use text verbatim
      • isPadText

        public boolean isPadText()
      • setPadText

        public void setPadText​(boolean padText)
        Ensure that text immediately preceded by or followed by an element will be "padded" with a single space. This is used to allow make browser-friendly HTML, avoiding trimText's transformation of, e.g., The quick <b>brown</b> fox into The quick<b>brown</b>fox (the latter will run the three separate words together into a single word). This setting is not too useful if you haven't also called setTrimText(boolean). The padding string will only be added if the text itself starts or ends with some whitespace characters. Default: false
        Parameters:
        padText - boolean if true, pad string-element boundaries
      • getIndent

        public java.lang.String getIndent()
      • setIndent

        public void setIndent​(java.lang.String indent)
        This will set the indent String to use; this is usually a String of empty spaces. If you pass null, or the empty string (""), then no indentation will happen. Default: none (null)
        Parameters:
        indent - String to use for indentation.
      • setIndent

        public void setIndent​(boolean doIndent)
        Set the indent on or off. If setting on, will use the value of STANDARD_INDENT, which is usually two spaces.
        Parameters:
        doIndent - if true, set indenting on; if false, set indenting off
      • setIndentSize

        public void setIndentSize​(int indentSize)
        This will set the indent String's size; an indentSize of 4 would result in the indention being equivalent to the String "    " (four space characters).
        Parameters:
        indentSize - int number of spaces in indentation.
      • isXHTML

        public boolean isXHTML()
        Whether or not to use the XHTML standard: like HTML but passes an XML parser with real, closed tags. Also, XHTML CDATA sections will be output with the CDATA delimiters: ( " <![CDATA[ " and " ]]> " ) otherwise, the class HTMLWriter will output the CDATA text, but not the delimiters. Default is false
        Returns:
        DOCUMENT ME!
      • setXHTML

        public void setXHTML​(boolean xhtml)
        This will set whether or not to use the XHTML standard: like HTML but passes an XML parser with real, closed tags. Also, XHTML CDATA sections will be output with the CDATA delimiters: ( " <[CDATA[ " and " ]]< ) otherwise, the class HTMLWriter will output the CDATA text, but not the delimiters. Default: false
        Parameters:
        xhtml - boolean true → conform to XHTML, false → conform to HTML, can have unclosed tags, etc.
      • getNewLineAfterNTags

        public int getNewLineAfterNTags()
      • setNewLineAfterNTags

        public void setNewLineAfterNTags​(int tagCount)
        Controls output of a line.separator every tagCount tags when isNewlines is false. If tagCount equals zero, it means don't do anything special. If greater than zero, then a line.separator will be output after tagCount tags have been output. Used when you would like to squeeze the html as much as possible, but some browsers don't like really long lines. A tag count of 10 would produce a line.separator in the output after 10 close tags (including single tags).
        Parameters:
        tagCount - DOCUMENT ME!
      • getAttributeQuoteCharacter

        public char getAttributeQuoteCharacter()
      • setAttributeQuoteCharacter

        public void setAttributeQuoteCharacter​(char quoteChar)
        Sets the character used to quote attribute values. The specified character must be a valid XML attribute quote character, otherwise an IllegalArgumentException will be thrown.
        Parameters:
        quoteChar - The character to use when quoting attribute values.
        Throws:
        java.lang.IllegalArgumentException - If the specified character is not a valid XML attribute quote character.

        public int parseOptions​(java.lang.String[] args,
                                int i)
        Parses command line arguments of the form -omitEncoding -indentSize 3 -newlines -trimText
        Parameters:
        args - is the array of command line arguments
        i - is the index in args to start parsing options

        public static OutputFormat createPrettyPrint()
