Question

I have a scenario where I cannot control the input data, for example, my input can be

<phoneNumber>6504323957</phoneNumber>

or

<phoneNumber>650-432-3957</phoneNumber>

or

<phoneNumber>[phone]</phoneNumber>

or

<phoneNumber>650.432.3957</phoneNumber>

however my output should always be like this

<areaCode>650</areaCode>
<phoneNumber>432-3957</phoneNumber>

I’m trying to achieve this using the following xsl, which works only for one condition not for other.

<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<xsl:element name="areaCode">
<xsl:value-of select="substring(phoneNumber,1,3)"/>
</xsl:element>
<xsl:element name="phoneNumber">
<xsl:value-of select="substring(phoneNumber,5,12)"/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>

Answer 1

Try

<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
    <xsl:variable name="numbersonly" select="translate(phoneNumber, translate(phoneNumber,'0123456789',''), '')"/>
    <xsl:element name="areaCode">
        <xsl:value-of select="substring($numbersonly,1,3)"/>
    </xsl:element>
    <xsl:element name="phoneNumber">
        <xsl:value-of select="substring($numbersonly,4,3)"/>-<xsl:value-of select="substring($numbersonly,7,4)"/>
    </xsl:element>
</xsl:template>

To handle input without area code you could use some simple math, and select from the right instead of from the left (assuming a full phone is 10 digits)..

<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
    <xsl:variable name="numbersonly" select="translate(phoneNumber, translate(phoneNumber,'0123456789',''), '')"/>
    <xsl:variable name="length" select="string-length($numbersonly)"/>
    <xsl:element name="areaCode">
        <xsl:value-of select="substring($numbersonly,$length -9,3)"/>
    </xsl:element>
    <xsl:element name="phoneNumber">
        <xsl:value-of select="substring($numbersonly,$length -6,3)"/>-<xsl:value-of select="substring($numbersonly,$length -3,4)"/>
    </xsl:element>
</xsl:template>
