<xsl:copy> introduces inappropriate line-end characters processing comments

• Key: XALANJ-656

Description

I was trying to write a template that would correctly reproduce the script
body of a JavaScript (which is typically 'masked' by a comment). My initial
attempt was:

<xsl:template match="script/comment()">
<xsl:copy/>
</xsl:template>

which worked, except that the copied script contained newline (ASCII 10)
in place of the carriage-return (ASCII 13) characters in the original. Note
that this is on a Macintosh, where line-endings are terminated by CR
rather than LF; I suspect it wouldn't manifest as a problem on UN*X). My
guess is that in this case, <xsl:copy> is causing Xalan to simply write LF's
rather than the appropriate platform-specific line terminators.

A workaround is to use:

<xsl:template match="script/comment()">
<xsl:comment><xsl:value-of select="."/></xsl:comment>
</xsl:template>
