How do I add adjustable * to format ssn in XSL?-CodePudding

I am working with Xsl and I was trying to add * in SSNs and wasn't sure how to go about it. I have done some research and concat() might be my answer but not sure how I could add *'s in there? Some SSNs are 4 characters long and some are 9 characters and some are just empty.

Example XML

<information>
    <secondBranch>
        <xsl:if test="Check = N">
        <SSN>771717771</SSN>
    </secondBranch>
    <secondBranch>
        <xsl:if test="Check = Y">
        <SSN>9991</SSN>
    </secondBranch>
    <secondBranch>
        <xsl:if test="Check = N">
        </SSN>
    </secondBranch>
</information>

Example XSL

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="3.0">
    <xsl:output method="text"/>
    <xsl:template match="/">
        <table>
            <title>
            </title>
            <body>
                <tr>
                    <th>
                        SSN
                    </th>
                </tr>
                <td>
                    <xsl:for-each select="/information/secondBranch">
                        <tr>
                            <xsl:value-of select="SSN"/>
                        </tr>
                    </xsl:for-each>
                </td>
            </body>
        </table>
    </xsl:template>
</xsl:stylesheet>

I am trying to make them look like this

SSN
771717771
*****9991
*********

What I am getting is this

CodePudding user response：

Instead of :

<tr>
    <xsl:value-of select="SSN"/>
</tr>

try:

<tr>
    <xsl:value-of select="substring('*********', string-length(SSN) 1)"/> 
    <xsl:value-of select="SSN"/>
</tr>

Added:

To output only SSN values with Check values of "Y", change:

<xsl:for-each select="/information/secondBranch">

to:

<xsl:for-each select="/information/secondBranch[Check='Y']">
