I don't think that's any more magical than surround it with single-quotes so it doesn't terminate the string. It will work in single- and double-quoted strings equally, so you don't have to worry about switching from one to the other messing up the expression. David

[PHP] Re: Xpath arguments in variable
If you needed the double-quotes in the Xpath expression when the constant is used , then you probably need them in the variable version. $v = $row-xpath('//membernumber[. = '.$MemberId.']'); That should put the double-quotes in for you...

Re: [PHP] Re: Xpath arguments in variable
Managed to resolve it. Phew! $v = $row-xpath('//membernumber[. = ' . '' . $MemberId . '' . ']'); works.

Re: [PHP] Re: Xpath arguments in variable
And let's not forget $v = $row-xpath(//membernumber[. = \$MemberId\]); The \ inside the string turns into a double-quote and using to delimit the string allows for variable substitution.
