How to output ampersand (&) from XSLT

问题

I'm converting all & into & in my XML so that the XSLT will compile. I'm styling the XML into HTML. However when a textbox is populated by the XSLT, I need the & to display as &.

For example, it shows "you & me" in the text box, but I need to see "you & me".

How to output `&` as `&` in XSLT

In general, here are alternative techniques for outputting & as &:

Globally:

<xsl:output method="html"/>
or
<xsl:output method="text"/>`

For ampersands originating from XSLT:

<xsl:text disable-output-escaping="yes"><![CDATA[&]]></xsl:text>

For ampersands originating from input XML:

<xsl:value-of select="XPATH EXPRESSION" disable-output-escaping="yes"/>

Now, in your specific case you say that &s within text boxes are being displayed as "&". I don't see that at all. Apart from XML or XSLT, in which I show above how to generate & rather than &, HTML itself really has no problem with &...

Consider this simple test HTML:

<html>
  <body>
    <h3>No &amp;amp; is displayed in any of these cases:</h3>
    <div>
      In an input box:
      <input type="text" value="Ampersand: &amp;"/>
    </div>
    <div>
      In a text area:
      <textarea>Ampersand: &amp;</textarea>
    </div>
    <div>In a div: Ampersand: &amp;</div>
  </body>
</html>

This renders in browsers as follows:
