How do I display the copyright symbol in an XPage?

问题

This seems like it should be simple. Using the escape sequence of © doesn't work when I enter this as text. The XPages engine keeps escaping the ampersand character, causing the string to be written as a literal.

回答1:

XPages is XML and it doesn't know the HTML escape characters, hence the "escaping" of the © symbol. I stumble over the same problem when designing XSLT stylesheets that output HTML. What should work is: ©. Are you planting the code in the source of the XPage or do you compute it? If you compute it, make sure you pick the "HTML" option (escaped=false), not plain text.

Let us know how it goes.

回答2:

Can you use the copyright symbol directly? © (Unicode code point U+00A9.)

Wikipedia has several other options that may also work.

回答3:

You can turn escaping off on a xp:text

<xp:text escape="false">
   <xp:this.value><![CDATA[&copy]]></xp:this.value>
</xp:text>
