XSLT function for escaping quotes?

I have some XSLT that gets an attribute and sends it as part of the URL to a php $_GET variable. It looks like this: 

<xsl:attribute name="href">search.php?subject="<xsl:value-of select="@level1"/>"</xsl:attribute>

It works with most values of @level1. For instance, if the value is foo, I get this url: 

search.php?subject="foo"

The problem is, when that value of @level1 contains a quotation mark, like "bar" etc etc it doesn't work. I get this: 

search.php?subject=""bar" etc etc"

Which of course returns an empty subject. If I add backslashes, suddenly it works. For instance, if I edit the URL to read: 

search.php?subject="\"bar\" etc etc"

then $_GET['subject]=="bar" etc etc! So how can I get XSL to add backslashes to escape these rogue quotation marks? I tried 

<xsl:attribute name="href">search.php?subject="<xsl:value-of select='replace(@level1,",\")'/>"</xsl:attribute>

and I tried

<xsl:attribute name="href">search.php?subject="<xsl:value-of select="replace(@level1,&quot;,\&quot;"/>"</xsl:attribute>

But nothing seems to work yet.

In XSLT 2.0 use the replace() function.

In XSLT 1.0 use the recursive exslt:replace template which you can find at http://www.exslt.org

(And either way, when you ask questions about XSLT, tell us which version you are using).
