I am using pattern matching to match file extension with my expression String for which code is as follows:-
public static enum FileExtensionPattern
{
WORDDOC_PATTERN( "([^\\s]+(\\.(?i)(txt|docx|doc))$)" ), PDF_PATTERN(
"([^\\s]+(\\.(?i)(pdf))$)" );
private String pattern = null;
FileExtensionPattern( String pattern )
{
this.pattern = pattern;
}
public String getPattern()
{
return pattern;
}
}
pattern = Pattern.compile( FileExtensionPattern.WORDDOC_PATTERN.getPattern() );
matcher = pattern.matcher( fileName );
if ( matcher.matches() )
icon = "blue-document-word.png";
when file name comes as "Home & Artifact.docx" still matcher.matches returns false.It works fine with filename with ".doc" extension.
Can you please point out what i am doing wrong.
"Home & Artifact.docx" contains spaces. Since you allow any char except whitespaces [^\s]+
, this filename is not matched.
Try this instead:
(.+?(\.(?i)(txt|docx|doc))$
