Extract URL link from src attribute of script tag in html through XSLT
Question
Is there a way to extract URL link specified inside src attribute of tag in a HTML file using XSLT?
The HTML file is like this -
<HTML>
<BODY>
<SCRIPT language="javascript" src="http://myspace.com" type="text/javascript"></script>
</BODY>
</HTML>
How do I code this in XSLT? I want to extract the URL in a variable which I then use it to pass to another function.
Many thanks.

Use xsl:variable to store an attribute value. Later, refer to it as $name-of-variable .
I have slightly adapted your input HTML, that is, lowercased all element names. It is uncommon to have uppercase names in HTML. Besides, your script element ends with a lowercased name anyway, which renders it malformed because XML names are case-sensitive.
Do not overcomplicate things. Depending on what you actually want to achieve it might not be necessary to store the attribute value in a variable.
Stylesheet
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:variable name="link" select="//script/@src"/>
<xsl:template match="/">
<link>
<xsl:value-of select="$link"/>
</link>
</xsl:template>
</xsl:stylesheet>
Output
<?xml version="1.0" encoding="UTF-8"?>
<link>http://myspace.com</link>
