Then I would do

<xsl:variable name="quot">"</xsl:variable>
<xsl:variable name="apos">'</xsl:variable>
<xsl:variable name="cue">src='</xsl:variable>
<xsl:variable name="v" select="translate($in, $quot, $apos)"/>
<xsl:variable name="w" select="translate($in, ' ', '')"/>
<xsl:value-of select="substring-before(substring-after($w, $cue), $apos)"/>
