I have this string supplier_id ~|(~ '3422' ~)|~supplier_name ~|(~ 'WD Ltd.' ~)|~project_personnel ~|(~ 'Yaya Toure (temp)' ~)|~lt_project_code ~|(~ '013-7718321' ~)|~ id ~|(~ '668'
and I need to get content inside ~|(~data~)|~
. I use listGetAt
with delimiter. The problem is some data inside delimiter contain bracket (
which ruin the search. For example with Yaya Toure (temp)
that contain bracket.
<cfoutput>
<cfset test = "supplier_id ~|(~ '3422' ~)|~supplier_name ~|(~ 'WD Ltd.' ~)|~project_personnel ~|(~ 'Yaya Toure (temp)' ~)|~lt_project_code ~|(~ '013-7718321' ~)|~ id ~|(~ '668'">
#test#
<cfset count_column = ListLen(test, "~)|~")>
<cfset column_name = ''>
<cfloop index="i" from="1" to=8 >
<cfif i mod 2 EQ 0>
<cfset column_name = ListAppend(column_name,listGetAt(test, i, "~|(~~)|~" ),",")>
</cfif>
</cfloop>
<br>
<br>
Result : #column_name#
</cfoutput>
Output : Result : '3422' , 'WD Ltd.' , 'Yaya Toure ,'
My expected result is : '3422' , 'WD Ltd.' , 'Yaya Toure (temp)' , '013-7718321'
. It will work if I removed (temp)
from the string. Please assist me with this and thanks in advance.
Option 1: Use a CF list function that supports multi-character delimiters, like listToArray.
<cfscript>
// split on first delimiter get "name->value" string
nameValuePairs = test.listToArray("~)|~" , false, true);
columnValues = [];
nameValuePairs.each(function(pair, index) {
// split on second delimiter to extract value
local.data = pair.listToArray("~|(~", false, true);
columnValues.append( local.data[ 2 ] );
});
writeDump( "Result 1: "& columnValues.toList() );
</cfscript>
Option 2: If you can identify a single character that's never present within the values, perhaps a non-printable character, just replace the existing delimiters, and loop as usual.
<cfscript>
// 31 == Unit separator
delim = chr(31);
newString = test.replace( "~)|~", delim, "all")
.replace( "~|(~", delim, "all");
columnValues = [];
newString.listToArray( delim ).each(function( elem, index) {
if (index mod 2 == 0) {
columnValues.append( elem );
}
});
WriteOutput( "<br>Result 2: "& columnValues.toList() );
</cfscript>
problem though for this string
supp~|(~lier_isd ~|(~ '3422' ~)|~supplier_name ~|(~ 'WD Ltd.' ~)|~project_personnel ~|(~ 'Yaya Toure (temp)' ~)|~lt_project_code ~|(~ '013-7718321' ~)|~ id ~|(~ '668'
I was expectinglier_isd ~|(~ '3422', 'WD Ltd.', 'Yaya Toure (temp)', '013-7718321'
The initial string appeared to use the format name ~|(~ value ~)|~
. However, if the value itself can contain one of the list delimiters ~|(~
, you won't be able to use list functions, because the function can't differentiate between when ~|(~
is acting as a delimiter and when it's part of a value. You'll need to use a regex instead. That's not my forte, but something like this should work
values = [];
// Find groups of "~|(~ value ~)|~"
matches = reMatch( "~\|\(~(.+?)(?=~\)\|~)", test);
matches.each( function(item, index) {
// remove text up to and including the first "~|(~"
local.str = reReplace( item, ".*?~\|\(~", "");
values.append( local.str );
});
WriteOutput( "Result 1: "& values.toList() );
