Regular Expression Help

I want to have regex which shouldn't match if any whitespace, ", } comes just after {
example-

1. { abc} should not be matched as it has space after {
2. {"abc"} should not be matched as it has " just after {
3. {} and { } should not be matched as it doesn't have anything between {}
4. {mostRecentAffiliation|textonly='false'|urlonly='t rue'|affiliationtype='school'|linkToForMostRecentA ffiliationTags='member_list'} should be matched
5. {school|append=' class list'|linkToForAffiliationTags='classlist'} should be matched
6. <div class=\"color2 text2 customFont txtColor21 floatLeft\">HOTTEST</div>"
+ "<div class=\"floatLeft redArrow\"></div>"
+ "<div class=\"floatLeft txtColor21\">"
+ "<a href=\"{mostRecentAffiliation|textonly='false'|url only='true'|affiliationtype='school'|linkToForMost RecentAffiliationTags='member_list'}\" class=\"link2 txtColor21\"> Check Your Class List</a> | <a href=\"{mostRecentAffiliation|textonly='false'|url only='true'|affiliationtype='school'|linkToForMost RecentAffiliationTags='member_list'}\" class=\"link2 txtColor21\">See Other Profiles</a>"
+ "</div>

it should pick {mostRecentAffiliation|textonly='false'|urlonly='t rue'|affiliationtype='school'|linkToForMostRecentA ffiliationTags='member_list'} twice

Please let me know if you can find something to handle this
I am also trying but somehow something is missing.

I have junit test case as

Code:

@Test public void checkTagPattern() { Pattern tagPattern = Pattern.compile("\\{([^\\}]+)\\}");// \\{([^\\}]+)\\} String contentWithDuplicateTag = "<div class=\"color2 text2 customFont txtColor21 floatLeft\">HOTTEST</div>" + "<div class=\"floatLeft redArrow\"></div>" + "<div class=\"floatLeft txtColor21\">" + "<a href=\"{mostRecentAffiliation|textonly='false'|urlonly='true'|affiliationtype='school'|linkToForMostRecentAffiliationTags='member_list'}\" class=\"link2 txtColor21\"> Check Your Class List</a> | <a href=\"{mostRecentAffiliation|textonly='false'|urlonly='true'|affiliationtype='school'|linkToForMostRecentAffiliationTags='member_list'}\" class=\"link2 txtColor21\">See Other Profiles</a>" + "</div>"; String contentString1 = "<style> .hpOverlay{ opacity:0.5; }"; String contentString2 = "body.ie .hpOverlay{ filter: alpha(opacity=50); }"; String contentString3 = "<B>{school|append=' class list'|linkToForAffiliationTags='classlist'}</a></b>"; String contentString4 = "cacheImage : function(indx,cache){\r\n if(!indx) indx =0;\r\n\t if(flashBacksMV.cachedImages.length < largeImagesList.length) {\r\n\t if(!cache) {$(\"#FBCachedImages\").append(\"<img src=\\\"\"+flashBacksMV.nonCachedImages[indx]+\"\\\" style=\\\"width:534px;height:370px;border:0\\\">\")"; String contentString5 = "<a href=\"{mostRecentAffiliation|textonly='false'|urlonly='true'|affiliationtype='school'|linkToForMostRecentAffiliationTags='member_list'}\" class=\"link2 txtColor21\"> Check Your Class List</a> | <a href=\"{mostRecentAffiliation|textonly='false'|urlonly='true'|affiliationtype='school'|linkToForMostRecentAffiliationTags='member_list'}\" class=\"link2 txtColor21\">See Other Profiles</a>"; String contentString6 = "<style> .hpOverlay{}"; String contentString7 = "<style> .hpOverlay{ }"; Matcher matcher1 = tagPattern.matcher(contentString1); Matcher matcher2 = tagPattern.matcher(contentString2); Matcher matcher3 = tagPattern.matcher(contentWithDuplicateTag); Matcher matcher4 = tagPattern.matcher(contentString3); Matcher matcher5 = tagPattern.matcher(contentString4); Matcher matcher6 = tagPattern.matcher(contentString5); Matcher matcher7 = tagPattern.matcher(contentString6); Matcher matcher8 = tagPattern.matcher(contentString7); assertFalse(matcher1.find()); assertFalse(matcher2.find()); assertFalse(matcher7.find()); assertFalse(matcher8.find()); assertTrue(matcher3.find()); assertFalse(matcher5.find()); assertTrue(matcher4.find()); assertTrue(matcher6.find()); // while (matcher4.find()) { // String group = matcher4.group(1); // assertEquals("school|append=' class list'|linkToForAffiliationTags='classlist'", // group); // } // while (matcher6.find()) { // String group = matcher6.group(1); // assertEquals( // "mostRecentAffiliation|textonly='false'|urlonly='true'|affiliationtype='school'|linkToForMostRecentAffiliationTags='member_list'", // group); // } }

If this test passes then uncomment the bottom code and comment these two lines
assertTrue(matcher4.find());
assertTrue(matcher6.find());

Please help.

Thanks in advance.
