ora:parseEscapedXML

Hi,
Oracle provides a custom xpath function,which can be used to convert a string representation of a XML input to a XML ,i.e the input which you are getting is a proper XML input but has been represented as a string.
The function is ora:parseEscapedXML(String).
One workaround is when we directly use this function in the XSLT,by default it does value-of,so the value of the XML input is selected.
Ex:
When we call this function and give the output of this function to a out variable the source looks like
xsl:value-of select="orcl:parseEscapedXML(/ns0:Message/ns0:msgData)"/

So the value of the variable msgData is passed instead of the XML.

This can be overcome by
1)Create a local XSLT variable pass the output of your function to this variable.
2)Use Copy-of and copy the variable to the required output variable
For Ex:
Replace the whole of
xsl:value-of select="orcl:parseEscapedXML(/ns0:Message/ns0:msgData)"/
with
xsl:variable name="parsedMsgData" select="orcl:parseEscapedXML(/ns0:Message/ns0:msgData)"/>
xsl:copy-of select="$parsedMsgData"/
