codepoints-to-string XML characters

hfmanson · November 26th, 2013, 10:27 AM

Hello,

XML 1.0 documents are not allowed to contain control characters other than U+0009, U+000A, U+000D. The XPath function codepoints-to-string follows this restriction. However when using <xsl:output method="text"/> codepoints-to-string still doesn't allow other control characters. Shouldn't codepoints-to-string allow any Unicode character when the output is text?

Example:

Code:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="2.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    exclude-result-prefixes="xsl xs">

<xsl:output method="text" encoding="ISO-8859-1"/>

<xsl:template match="text()|@*">
</xsl:template>

<xsl:template match="/">
<xsl:value-of select="codepoints-to-string((16))"/>
</xsl:template>

</xsl:stylesheet>

Kind regards,

For better or worse, the restrictions on character set are present in the XDM data model and the string data type, not only in serialized XML.
