Please try the XSL -

<?xml version="1.0"?> 
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
  
<xsl:variable name="str"
select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'" />
  
<xsl:template match="node()">
   <xsl:copy>       
      <xsl:for-each select="@*">
        <xsl:attribute name="{name()}">
          <xsl:variable name="att-val" select="." />
          <xsl:call-template name="stripchars">
             <xsl:with-param name="x"
select="substring($att-val, 1, 1)" /> 
             <xsl:with-param name="y"
select="substring(., 2, string-length($att-val))" /> 
          </xsl:call-template>
        </xsl:attribute>
      </xsl:for-each>
      <xsl:apply-templates />
   </xsl:copy>
</xsl:template>  
  
<xsl:template name="stripchars">
  <xsl:param name="x" />
  <xsl:param name="y" />
    
  <xsl:if test="contains($str, $x)">
    <xsl:value-of select="$x" />
  </xsl:if>
    
  <xsl:if test="string-length($y) > 0">
     <xsl:call-template name="stripchars">
       <xsl:with-param name="x" select="substring($y,
1, 1)" /> 
       <xsl:with-param name="y" select="substring($y,
2, string-length($y))" /> 
     </xsl:call-template> 
  </xsl:if>
</xsl:template>
 
</xsl:stylesheet>

for e.g. when it is applied to XML -

<?xml version="1.0"?>
<root>
  <a x="123ABC+-" />
  <b y="ABC12" />
  <c z="+-1" />
</root>

it produces output -

<?xml version="1.0"?>
<root>
  <a x="123ABC" />
  <b y="ABC12" />
  <c z="1" />
</root>

Regards,
Mukul
