Is it possible to put XSL instructions inside JavaScript?

[Matt]

Is it possible to put XSL instructions inside JavaScript?
For example, pop up a message box with the xml value: alert(value in xml);

Approach #1:
<script type="text/javascript">
alert(<xsl:value-of select="@id"/>);
</script>

It will have javascript errors

Approach #2:

<xsl:text>&lt;script type="text/javascript"&gt;</xsl:text>
<xsl:text>alert(</xsl:text>
<xsl:value-of select="@id"/><xsl:text>)</xsl:text>
<xsl:text>&lt;/script&gt;</xsl:text>

If I try the following, it will display the javascript as text,
not the javascript message box in browser.

any ideas?? thanks!!

The answer to that question would be a question about javascript but you
appear to be writing XSLT. (The actual character data being written by
xslt might be javascript, but XSLT doesn't care about that, it could
just as well be english or french.

For example, pop up a message box with the xml value: alert(value in xml);

Approach #1:
<script type="text/javascript">
alert(<xsl:value-of select="@id"/>);
</script>

This is the correct xslt syntax, once xslt has run the output will be
<script type="text/javascript">
alert(something);
</script>
which if passed to an html browswer will take the content of the script
and pass it to the javascript engine.depending what your javascript is
doing you might want

alert("<xsl:value-of select="@id"/>");

so you end up with
alert("something");

It will have javascript errors

Approach #2:

<xsl:text>&lt;script type="text/javascript"&gt;</xsl:text>
<xsl:text>alert(</xsl:text>
<xsl:value-of select="@id"/><xsl:text>)</xsl:text>
<xsl:text>&lt;/script&gt;</xsl:text>

If I try the following, it will display the javascript as text,
not the javascript message box in browser.

Using &lt; quotes the < specifically so that it is taken as text not markup.
