Subject: RE: [xsl] Passing through character entities intact From: "McCollum , Angus" <AMcCollum@xxxxxxxx> Date: Thu, 11 Oct 2001 10:01:36 -0400 |
Thanks to everyone for their posts on this topic. I now understand why entity references such as — are removed before XSLT processing. Unfortunately it seems like a common need to pass defined references through from the input document type to the output document type exists. If the XSLT transformation included an entity reference this can be passed through to the output document. Why then doesn't XSLT processors or the output XML serializer take a look at output document type and any included general entity declarations could matched to the output stream to replace with a reference. I noted that references such as & are passed through. Apparently they are not simply passed through but parsed as a '&' character and then substitued with a reference when the final document is written. If this works for XML's five entity references why can the serializer check for document specific references? -----Original Message----- From: Michael Kay [mailto:mhkay@xxxxxxxxxxxx] Sent: Thursday, October 11, 2001 5:27 AM To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: RE: [xsl] Passing through character entities intact > How do you take a character entity in an input document and > pass it through > to the output document as an entity(i.e. without any change)? You can't, because XSLT processes the tree produced by the XML parser, and that tree doesn't retain character entities. The trick is to turn the character entities into something else (e.g. a processing instruction) before XML parsing, which you can do by preprocessing e.g. in Perl.
