regular expressions in Ant
Hi
I have trouble converting \ to \\, for example in
\\filer\Test\PaC\M2\5.3, to \\\\filer\\Test\\PaC\\M2\\5.3.
I tried with ant-contrib's
<ac:propertyregex property="html_2"
input="${html_1}"
regexp="([\]"
replace="\\"
casesensitive="false"/>
But I get errors
C:\main.xml:452: java.util.regex.PatternSyntaxException: Unclosed
character class near index 3 ([\]
^
Thanks for sharing

Backslashes in Ant need to be escaped, as in any regular Java String:
<ac:propertyregex property="html_2"
input="${html_1}"
regexp="\\"
replace="\\\\"
casesensitive="false"/>
BR,
Olivier

[\] is open-character-class right-bracket. The exception is that you are missing a ']', making the pattern [\]] - matching a single right-bracket.
You mean [\\], or more simply \\.
To turn backslash into double backslash, try: regexp="\\" replace="\\\\"
