How do I escape the " in the replace command?

[Simon Jeffrey]

I am new to ant and I am trying to use the replace command to replace a
string that contains the " character.

Thanks

you have to provide more details =

What did you try already ?
Have you tried with regexp ?
Where comes that string from, is it part of a file ?
How does the file look like ?
...

btw. in regular expressions the quote or double quote
characters are not special, no metacharacters like f.e.
[ \ ^ $ . | ? .... etc.
so you don't need to escape them

I am trying to execute the command below as part of our weblogic
install.

Yes the string is part of a file.

I have tried using "e;, \", and \Q \E, but none of these options has
worked.

I was not aware of the regexp option.

Thanks, Jeff


<replace file="${env.DOMAINDIR}/bin/setDomainEnv.${fileext}"
  token="JAVA_OPTIONS=\"${JAVA_OPTIONS}\""
  value="JAVA_OPTIONS=\"${JAVA_OPTIONS}
-Dweblogic.ProductionModeEnabled=${WEBLOGIC_PRODUCTION_MODE}\""/>

untested, try with =

    <replace file="${env.DOMAINDIR}/bin/setDomainEnv.${fileext}"
   token='JAVA_OPTIONS="${JAVA_OPTIONS}"'
   value='JAVA_OPTIONS="${JAVA_OPTIONS}"
-Dweblogic.ProductionModeEnabled=${WEBLOGIC_PRODUCTION_MODE}'/>

if that doesn't work, i would go with regexp

The HTML entity for " is ", not "e;
(http://www.w3.org/TR/html401/sgml/entities.html#h-24.4.1). Did the OP
have a typo in his e-mail, or did he try the wrong entity?

btw. after a second look, regardless whether a solution with
regexp would be more suitable =

i don't understand your try to mask ${JAVA_OPTIONS} with \" ... \"
if you simply write ${...} it will be replaced with the contents/the
value of the property at runtime

 ${JAVA_OPTIONS} appears in this file many times.  I only want this
specific instance (JAVA_OPTIONS="${JAVA_OPTIONS}") to be replaced, not
the others.

Thanks, Jeff

don't know if he had a typo in it, but you're right,
of course it should be " instead of "e;

but i think =

<replace file="${env.DOMAINDIR}/bin/setDomainEnv.${fileext}"
  token='JAVA_OPTIONS="${JAVA_OPTIONS}"'
  value='JAVA_OPTIONS="${JAVA_OPTIONS}"
  -Dweblogic.ProductionModeEnabled=${WEBLOGIC_PRODUCTION_MODE}'/>

is equivalent to

<replace file="${env.DOMAINDIR}/bin/setDomainEnv.${fileext}"
  token="JAVA_OPTIONS="${JAVA_OPTIONS}""
  value="JAVA_OPTIONS="${JAVA_OPTIONS}"
  -Dweblogic.ProductionModeEnabled=${WEBLOGIC_PRODUCTION_MODE}"/>

when the later is the 'cleaner' version, but also more
chars to write ;-)


Regars, Gilbert

This version below works :) !!! Very good to know, and really the
easiest, most straight-forward way to handle double qoutes in your
source and target strings.

<replace file="testfile.txt"
          token='JAVA_OPTIONS="${JAVA_OPTIONS}"'
          value='JAVA_OPTIONS="${JAVA_OPTIONS}
-Dweblogic.ProductionModeEnabled=${WEBLOGIC_PRODUCTION_MODE}"'/>

"The HTML entity for " is ", not "e;

It was not a type-o in the email...I had it wrong.

Thanks everyone VERY MUCH!!!  Now hopefully it will work on unix as well
(I've only tested on windows so far.)


Thanks, Jeff

works here on linux with ant 1.7.0/jdk 6, @work those '"'
stuff runs on AIX, should work on your unix box also
"write once run (debug) anywhere" ;-)
