I‘m using TouchXML for parsing WSDL file, and i'm a new to it, There's a NSString like this
NSString *str = #"<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"><soap:Body><ns1:createSessionResponse xmlns:ns1=\"http://soap.user/\"><ns1:out>9E0B34E6DFF7BF89</ns1:out></ns1:createSessionResponse></soap:Body></soap:Envelope>";
How can I get the string 9E0B34E6DFF7BF89 in "ns:out"
Try this :
NSString *str = #"<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"><soap:Body><ns1:createSessionResponse xmlns:ns1=\"http://soap.user/\"><ns1:out>9E0B34E6DFF7BF89</ns1:out></ns1:createSessionResponse></soap:Body></soap:Envelope>";
NSRange rr2 = [str rangeOfString:#"<ns1:out>"];
NSRange rr3 = [str rangeOfString:#"</ns1:out>"];
int lengt = rr3.location - rr2.location - rr2.length;
int location = rr2.location + rr2.length;
NSRange aa;
aa.location = location;
aa.length = lengt;
str = [str substringWithRange:aa];
NSLog(#"%#",str); // 9E0B34E6DFF7BF89

I am new in objective and I'm facing my first problem, and I can not continue my first project.
it's quite simple, I have a NSString :
NSString *myString = #"<font face='Helvetica' size=25 color='#d79198'> Here is some text !</font>";
what I want to do is to get the value of the size "25" which is always 2 char long, so I can calculate my UILabel size.
i know how to detect if there is the substring I am looking for "size=" using :
if ([string rangeOfString:#"bla"].location == NSNotFound)
but I have not found or not understand how to extract the string #"size=XX" and then get the XX as a NSString from *myString
Thank for any help.
NSString *myString = #"<font face='Helvetica' size=25 color='#d79198'> Here is some text !</font>";
NSRange range = [myString rangeOfString:#"size="];
if (range.location != NSNotFound)
{
NSLog(#"Found \"size=\" at %d", range.location);
NSString *sizeString = [myString substringWithRange:NSMakeRange(range.location+5, 2)];
NSLog(#"sizeString: %#", sizeString);
}
This should do the trick. You could also at the end do this: int sizeFont = [sizeString intValue];
NSString *myString = #"<font face='Helvetica' size=25 color='#d79198'> Here is some text !</font>";
if ([myString rangeOfString:#"size"].location != NSNotFound)
{
myString = [myString substringFromIndex:[myString rangeOfString:#"size"].location];
myString = [myString substringToIndex:[myString rangeOfString:#" "].location]; // Now , myString ---> size=25 color='#d79198'> Here is some text !</font>
myString = [myString substringFromIndex:[myString length]-2];// Now, myString ---> size=25
NSLog(#"myString -- %#",myString); // Now, myString ---> 25
}
If you have string like stack:overflow then use it as follow :
NSString *Base=#"stack:overflow"
NSString *one = [[Base componentsSeparatedByString:#":"] objectAtIndex:0];
NSString *two = [[Base componentsSeparatedByString:#":"] objectAtIndex:1];
In this case one = stack and two=overflow
Part of an HTML page? Then use the tool that is designed for the task.
You could calculate the range of the number yourself or use a very simple regular expression to get the substring, something like
(?<=size\=)\d*
This means that you are searching for digits (\d*) that is preceded by "size=" ((?<=size\=))
Which using NSRegularExpression would be
NSError *error = NULL;
NSRegularExpression *regex =
[NSRegularExpression regularExpressionWithPattern:#"(?<=size\\=)\\d*"
options:0
error:&error];
NSTextCheckingResult *match =
[regex firstMatchInString:myString
options:0
range:NSMakeRange(0, [myString length])];
NSString *sizeText = [myString substringWithRange:match.range];
Finally you should convert the text "25" into a number using
NSInteger size = [sizeText integerValue];
Use componentsSeparatedByString: method...
NSString *myString = #"<font face='Helvetica' size=25 color='#d79198'> Here is some text !</font>";
NSString *theSizeString = [[[[myString componentsSeparatedByString:#" "] objectAtIndex:2] componentsSeparatedByString:#"="] objectAtIndex:1];
NSLog(#"The sizestring:%#",theSizeString);
I think it will be helpful to you.
You can get the range of the string #"size=". The range has location and length. So what you need next is to call on the myString the substringWithRange: method. The parameter would be an NSRage starting from the location+length of #"size=" and length of 2.
I need to get substring CODE's value (X2.31) from string
NSString *str = #"SHMU=\"\" CODE=\"X2.31\" XTN=\";
How could I get that particular substring?
Try the below one
NSString *str = #"SHMU=\"\" CODE=\"X2.31\" XTN=\"";
NSRange range = [str rangeOfString:#"CODE="];
NSString *substring = [[str substringFromIndex:NSMaxRange(range)] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
NSArray *str1 = [substring componentsSeparatedByString:#" "];
NSLog(#"the sub %#",[[str1 objectAtIndex:0] stringByTrimmingCharactersInSet[NSCharacterSet whitespaceCharacterSet]]);
And by string was "X2.31"
NSString *strOrg = [NSString stringWithFormat:#"%#",#"SHMU=\"\" CODE=\"X2.31\" XTN=\""] ;
NSString *strLeft = [NSString stringWithFormat:#"%#",#"SHMU=\"\" CODE=\""] ;
NSString *strRight = [NSString stringWithFormat:#"%#",#"\" XTN=\""] ;
NSLog(#"%#", [self getDataBetweenString:strOrg LeftString:strLeft RightString:strRight LeftOffset:13]);
- (NSString *)getDataBetweenString:(NSString *)orgString LeftString:(NSString *)leftString RightString:(NSString *)rightString LeftOffset:(NSInteger)leftPos;
{
NSInteger left, right;
NSString *foundData;
NSScanner *scanner=[NSScanner scannerWithString:orgString];
[scanner scanUpToString:leftString intoString: nil];
left = [scanner scanLocation];
[scanner setScanLocation:left + leftPos];
[scanner scanUpToString:rightString intoString: nil];
right = [scanner scanLocation] + 1;
left += leftPos;
foundData = [orgString substringWithRange: NSMakeRange(left, (right - left) - 1)]; return foundData;
}
This is only specific to the str you posted.
Your number must be followed by First X.
float f=[[str componentsSeparatedByString:#"X"][1] floatValue];
I'm new to iPhone development, I want to convert a string to hex format.
For example 00A400024F01 to 0x00,0xA4,0x00,0x02,0x4F,0x01 I guess I should start by dividing the string and then convert the grouped value. I don't know how to do that.
u just found answer from this stackoverflow question:-
How to convert an NSString to hex values
+ (NSString *) stringToHex:(NSString *)str
{
NSUInteger len = [str length];
unichar *chars = malloc(len * sizeof(unichar));
[str getCharacters:chars];
NSMutableString *hexString = [[NSMutableString alloc] init];
for(NSUInteger i = 0; i < len; i++ )
{
// [hexString [NSString stringWithFormat:#"%02x", chars[i]]]; /*previous input*/
[hexString appendFormat:#"%02x", chars[i]]; /*EDITED PER COMMENT BELOW*/
}
free(chars);
return [hexString autorelease];
}
UPDATE
You can divide one sting on to two string using below method:-
NSString * mystring = #"Hello,How are you";// suppos your string like that
NSArray * array = [mystring componentsSeparatedByString:#","];
NSString * str1 = [array objectAtIndex:0]; //Hello
NSString * str2 = [array objectAtIndex:1]; //How are you
and if you want to murge two string in to one string like :-
NSString *str1=#"hi Sweet Lady";
NSString *str2=#"How are you";
NSString *mainstr=[NSString stringWithFormat:#"%# %#",str1,str2];
Output is ==== hi Sweet Lady How are you
I have an NSString *str, having value #"I like Programming and gaming."
I have to remove "I" "like" & "and" from my string so it should look like as "Programming gaming"
How can I do this, any Idea?
NSString *newString = #"I like Programming and gaming.";
NSString *newString1 = [newString stringByReplacingOccurrencesOfString:#"I" withString:#""];
NSString *newString12 = [newString1 stringByReplacingOccurrencesOfString:#"like" withString:#""];
NSString *final = [newString12 stringByReplacingOccurrencesOfString:#"and" withString:#""];
Assigned to wrong string variable edited now it is fine
NSLog(#"%#",final);
output : Programming gaming
NSString * newString = [#"I like Programming and gaming." stringByReplacingOccurrencesOfString:#"I" withString:#""];
newString = [newString stringByReplacingOccurrencesOfString:#"like" withString:#""];
newString = [newString stringByReplacingOccurrencesOfString:#"and" withString:#""];
NSLog(#"%#", newString);
More efficient and maintainable than doing a bunch of stringByReplacing... calls in series:
NSSet* badWords = [NSSet setWithObjects:#"I", #"like", #"and", nil];
NSString* str = #"I like Programming and gaming.";
NSString* result = nil;
NSArray* parts = [str componentsSeparatedByString:#" "];
for (NSString* part in parts) {
if (! [badWords containsObject: part]) {
if (! result) {
//initialize result
result = part;
}
else {
//append to the result
result = [NSString stringWithFormat:#"%# %#", result, part];
}
}
}
It is an old question, but I'd like to show my solution:
NSArray* badWords = #[#"the", #"in", #"and", #"&",#"by"];
NSMutableString* mString = [NSMutableString stringWithString:str];
for (NSString* string in badWords) {
mString = [[mString stringByReplacingOccurrencesOfString:string withString:#""] mutableCopy];
}
return [NSString stringWithString:mString];
Make a mutable copy of your string (or initialize it as NSMutableString) and then use replaceOccurrencesOfString:withString:options:range: to replace a given string with #"" (empty string).
I'm developing an application for the iPhone that has inApp-mail sending capabilities. So far so good, but now I want to avoid html-injections as some parts of the mail are user-generated texts.
Basically I search for something like this:
// inits
NSString *sourceString = [NSString stringWithString:#"Hello world! Grüße dich Welt <-- This is in German."];
// ----- THAT'S WHAT I'M LOOKING FOR
// pseudo-code |
// V
NSString *htmlEncodedString = [sourceString htmlEncode];
// log
NSLog(#"source string: %#", sourceString);
NSLog(#"encoded string: %#", htmlEncodedString);
Expected output
source string: Hello world! Grüße dich Welt <-- This is in German.
encoded string: Hello world! Grüße dich Welt <-- This is in German.
I already googled and looked through several of SO's questions and answers, but all of them seem to be related to URL-encoding and that's not what I really need (I tried stringByAddingPercentEscapesUsingEncoding with no luck - it creates %C3%BC out of an 'ü' that should be an ü).
A code sample would be really great (correcting mine?)...

Check out my NSString category for HTML. Here are the methods available:
- (NSString *)stringByConvertingHTMLToPlainText;
- (NSString *)stringByDecodingHTMLEntities;
- (NSString *)stringByEncodingHTMLEntities;
- (NSString *)stringWithNewLinesAsBRs;
- (NSString *)stringByRemovingNewLinesAndWhitespace;
Thanks #all. I ended up using my own implementation:
//
// _________________________________________
//
// textToHtml
// _________________________________________
//
- (NSString*)textToHtml:(NSString*)htmlString {
htmlString = [htmlString stringByReplacingOccurrencesOfString:#"&" withString:#"&"];
htmlString = [htmlString stringByReplacingOccurrencesOfString:#"<" withString:#"<"];
htmlString = [htmlString stringByReplacingOccurrencesOfString:#">" withString:#">"];
htmlString = [htmlString stringByReplacingOccurrencesOfString:#"""" withString:#"""];
htmlString = [htmlString stringByReplacingOccurrencesOfString:#"'" withString:#"'"];
htmlString = [htmlString stringByReplacingOccurrencesOfString:#"\n" withString:#"<br>"];
return htmlString;
}
A little improvement on #Markus' code [Change <br /> to <p></p>, escape multiple spaces]
- (NSString*)textToHtml:(NSString*)htmlString {
htmlString = [htmlString stringByReplacingOccurrencesOfString:#"&" withString:#"&"];
htmlString = [htmlString stringByReplacingOccurrencesOfString:#"<" withString:#"<"];
htmlString = [htmlString stringByReplacingOccurrencesOfString:#">" withString:#">"];
htmlString = [htmlString stringByReplacingOccurrencesOfString:#"""" withString:#"""];
htmlString = [htmlString stringByReplacingOccurrencesOfString:#"'" withString:#"'"];
htmlString = [#"<p>" stringByAppendingString:htmlString];
htmlString = [htmlString stringByAppendingString:#"</p>"];
htmlString = [htmlString stringByReplacingOccurrencesOfString:#"\n" withString:#"</p><p>"];
// htmlString = [htmlString stringByReplacingOccurrencesOfString:#"\n" withString:#"<br />"];
while ([htmlString rangeOfString:#" "].length > 0) {
htmlString = [htmlString stringByReplacingOccurrencesOfString:#" " withString:#" "];
}
return htmlString;
}
I have been looking for a similar solution and this did the job for me
NSString* value = #"<&>";
const void* keys[1] = {CFSTR("somekey")};
const void* values[1] = {value};
CFDictionaryRef dicRef = CFDictionaryCreate(kCFAllocatorDefault, keys, values, 1, nil, nil);
CFDataRef dataRef = CFPropertyListCreateData(kCFAllocatorDefault, dicRef, kCFPropertyListXMLFormat_v1_0, 0, NULL);
NSString *str = [[NSString alloc]initWithData:(NSData *)dataRef encoding:NSUTF8StringEncoding];
NSRange start =[str rangeOfString:#"string>"];
NSRange end =[str rangeOfString:#"</string"];
NSString *substr = [str substringWithRange:NSMakeRange(start.location+start.length, end.location-(start.location+start.length))];
[str release];
CFRelease(dicRef);
CFRelease(dataRef);
//Substring is now html entity encoded
I am using some of the features that is used when saving plist files. I hope this helps.
I'm expanding #Markus answer, because my case is i'm sending JSON string, so i need to added some escape, these are my function :
note :

Assuming the character encoding of the email supports Unicode - say UTF-8 - could you not just find and replace the occurrences of <, >, and & with <, >, and &?
