How to get value from JavaScript

I need to get current URL and use the first part of the URL to other links.

I tried two ways but failed.  Can anyone help me with this?

First, I tried to assign xslt variable using JavaScript:
***************************  XSLT codes *************************
<xsl:stylesheet xmlns:xsl = "http://www.w3.org/1999/XSL/Transform"
					 xmlns:js="javascript:code" version = "1.1" > 
		
	<xsl:output method = "html" /> 

	<xsl:variable name="url">	
		<script language="javascript">
			var strID;
			var intLen;
			strID = window.document.location.toString();
			intLen = strID.indexOf('livelink.exe/fetch');
			strID = strID.substring(0, intLen);
			document.write(strID);
		</script>							
	</xsl:variable>
***************************  XSLT codes *************************

It consider all <script language="javascript">var strID;      .....> as the variable.


Second, I tried to use JavaScript inside the <xsl:attribut> that belong to an anchor, error message said can't put it in the attribute.

***************************  XSLT codes *************************
			<a>
			<xsl:attribute name="href">
			<script language='javascript'>
				var strID;
				var intLen;
				strID = window.document.location.toString();
				intLen = strID.indexOf('livelink.exe/fetch');
				strID = strID.substring(0, intLen);
				document.write(strID);
			</script>
			livelink.exe?func=ll&amp;objID=<xsl:value-of select="@id"/>&amp;objAction=View
			</xsl:attribute>
			<xsl:attribute name="target">_self</xsl:attribute>			
			<FONT SIZE="2" FACE="Arial,Helvetica,sans-serif">		
			<xsl:value-of select="@name" />			
			</FONT>
			</a>

***************************  XSLT codes *************************

Javascript is used to get the first part of the current URL and pass it to other links.
