backslash escaping in a regex
Hi, looked through the archive, but I don't think pathconvert can be
used in this case.
property file:
prop=E:\\foo\\bar
build file:
<replaceregexp file="${target.dir}/foobar.xml">
<regexp pattern="value="[^"]+""/>
<substitution expression="value="${prop}""/>
</replaceregexp>
actual result:
value="E:foobar"
desired result:
value="E:\foo\bar"
I also tried double escaping i.e.
prop=E:\\\\foo\\\\bar
but there all backslashes disappear as well.
thanks for pointers,
Jakob.

Hi Jacob
try this
${target.dir}/foobar.xml contents contains some well known regular expression match criteria as in space between E: foo and bar:
Property=E: foo bar
<replaceregexp match="\s+" replace="/" flags="g" byline="true" file="${src}/build.properties">
</replaceregexp>
the ${target.dir}/foobar.xml replaceregexp transforms whitespace character to /:
Property=E:/foo/bar
hth

Hi Stefan,
eight backslashes, wow! That means four intermediate steps to get from
\\\\\\\\ to \
I'll probably just go with the forward slashes in the property file
and pathconvert them to backslashes.
thanks a lot,
Jakob.

property files and backslahes are a pain.

I'm afraid you'd need eight of them. It may be simpler to use forward
slashes in your property file and <pathconvert> to translate them after
you've applied the regex.
