  private boolean m_disableOutputEscaping = false;

  
Set the "disable-output-escaping" attribute.
Normally, the xml output method escapes & and < (and
possibly other characters) when outputting text nodes.
This ensures that the output is well-formed XML. However,
it is sometimes convenient to be able to produce output
that is almost, but not quite well-formed XML; for
example, the output may include ill-formed sections
which are intended to be transformed into well-formed
XML by a subsequent non-XML aware process. For this reason,
XSLT provides a mechanism for disabling output escaping.
An xsl:value-of or xsl:text element may have a
disable-output-escaping attribute; the allowed values
are yes or no; the default is no; if the value is yes,
then a text node generated by instantiating the xsl:value-of
or xsl:text element should be output without any escaping.

Params:
  • v – Boolean value for "disable-output-escaping" attribute.
