xsl remove all non-numeric characters and leading 1
Solution 1
I. XSLT 1.0 solution:
This transformation:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="text()">
<xsl:variable name="vnumsOnly" select=
"translate(., translate(.,'0123456789',''), '')
"/>
<xsl:value-of select=
"substring($vnumsOnly, (substring($vnumsOnly,1,1)='1') +1)"/>
</xsl:template>
</xsl:stylesheet>
when applied on this XML document:
<t>"+1 (222) 333-4444 x 5555</t>
produces the wanted, correct result:
22233344445555
Explanation:
The expression:
translate(.,'0123456789','')
is evaluated to a string that contains all non-numeric characters in the current node.We use 1. above in the expression:
translate(., translate(.,'0123456789',''), '')
and this evaluates to a string where all non-numeric characters from the current node are deleted.
.3. The expression: (substring($vnumsOnly,1,1)='1') +1)"
evaluates to 2
if the first character of $vnumsOnly
is '1'
and it evaluates to 1
if the starting character isn't '1'.
.4. We use 3. in the following expression:
substring($vnumsOnly, (substring($vnumsOnly,1,1)='1') +1)
which evaluates to the same string $vnumsOnly
if it doesn't start with '1' and it evaluates to its substring starting from the 2nd character, if the first character is '1'.
II. XPath 2.0 solution:
Just use:
replace(replace(., '[^0-9]', ''), '^1', '')
The inner replace removes all characters that aren't 0 through 9 (digits). The outer replace removes the leading 1 (if it exists).
Solution 2
replace(replace(., '[^1-9]', ''), '^1', '') - I am responding to this... Instead of [^1-9]... Use [^0-9] otherwise any 0's in the phone number get deleted. But other than that this fixed my Workday integration issue great!

I need to convert incoming phone number strings to a standardized format that does not have any non-numeric characters and strips off the leading number if it is 1.
For example:
"+1 (222) 333-4444 x 5555" becomes "22233344445555"
Thanks in advance for your help!

MattM over 13 yearsThanks! This works perfectly. I really appreciate the explanation too.

Nateous over 9 years@DimitreNovatchev does this also work for the translate above?
translate($phone,'0123456789'+$phone,'0123456789')
instead oftranslate(., translate(.,'0123456789',''), '')
which is better? -
Dimitre Novatchev over 9 years@Nate, The expression you propose probably will produce the correct result. However, it can require extensive memory -- especially when the input string is significantly long. The "double-translate" method doesn't construct a second string that is longer than the input string.
