This is useful in many contexts, for example: <ol> <li>\e Validation. A regexp can be used to check whether a piece of text meets some criteria, e.g. is an integer or contains no whitespace. <li>\e Searching. Regexps provide a much more powerful means of searching text than simple string matching does. For example we can create a regexp which says "find one of the words 'mail', 'letter' or 'correspondence' but not any of the words 'email', 'mailman' 'mailer', 'letterbox' etc." <li><em>Search and Replace.</em> A regexp can be used to replace a pattern with a piece of text, for example replace all occurrences of '&' with '\&' except where the '&' is already followed by 'amp;'. <li><em>String Splitting.</em> A regexp can be used to identify where a string should be split into its component fields, e.g. splitting tab delimited strings. </ol> We present a very brief introduction to regexps, a description of Qt's regexp language, some code examples, and finally the function documentation. QRegExp is modelled on Perl's regexp engine and fully supports Unicode. QRegExp may also be used in the weaker 'wildcard' (globbing) mode which works in a similar way to command shells. A good text on regexps is <i>Mastering Regular Expressions: Powerful Techniques for Perl and Other Tools</i> by Jeffrey E. Friedl, ISBN 1565922573. Experienced regexp users may prefer to skip the introduction and go directly to the relevant information: <ul> <li><a href="#characters-and-abbreviations-for-sets-of-characters"> Characters and Abbreviations for Sets of Characters</a> <li><a href="#sets-of-characters">Sets of Characters</a> <li><a href="#quantifiers">Quantifiers</a> <li><a href="#capturing-text">Capturing Text</a> <li><a href="#assertions">Assertions</a> <li><a href="#wildcard-matching">Wildcard Matching (globbing)</a> <li><a href="#perl-users">Notes for Perl Users</a> <li><a href="#code-examples">Code Examples</a> <li><a href="#member-function-documentation">Member Function Documentation</a> </ul> <b>Introduction</b> Regexps are built up from expressions, quantifiers and assertions. The simplest form of expression is simply a character, e.g. <b>x</b> or <b>5</b>. An expression can also be a set of characters. For example, <b>[ABCD]</b>, will match an <b>A</b> or a <b>B</b> or a <b>C</b> or a <b>D</b>. As a shorthand we could write this as <b>[A-D]</b>. If we want to match any of the captital letters in the English alphabet we can write <b>[A-Z]</b>. A quantifier tells the regexp engine how many occurrences of the expression we want, e.g. <b>x{1,1}</b> means match an <b>x</b> which occurs at least once and at most once. We'll look at assertions and more complex expressions later. Note that regexps cannot be used to check for balanced brackets or tags (unless you know the maximum level of nesting). We'll start by writing a regexp to match integers in the range 0 to 99. We will require at least one digit so we will start with <b>[0-9]{1,1}</b> which means match a digit exactly once. This regexp alone will match integers in the range 0 to 9. To match one or two digits we can increase the maximum number of occurrences so the regexp becomes <b>[0-9]{1,2}</b> meaning match a digit at least once and at most twice. However, this regexp as it stands will not match correctly. This regexp will match one or two digits \e within a string. To ensure that we match against the whole string we must use the anchor assertions. We need <b>^</b> (caret) which when it is the first character in the regexp means that the regexp must match from the beginning of the string. And we also need <b>$</b> (dollar) which when it is the last character in the regexp means that the regexp must match until the end of the string. So now our regexp is <b>^[0-9]{1,2}$</b>. Note that assertions do not match any characters. If you've seen regexps elsewhere they may have looked different from @@ -422,3346 +428,3346 @@ '#define' followed by at least one whitespace followed by at least one word character optionally followed by whitespace. This regexp will match define's that exist but have no value, i.e. it will not match '#define INTMAX 32767' but it will match '#define <u>DEBUG</u>'. </ul> <a name="wildcard-matching"><b>Wildcard Matching (globbing)</b></a> Most command shells such as \e bash or \e cmd support "file globbing", the ability to identify a group of files by using wildcards. Wildcard matching is much simpler than full regexps and has only four features: <ul> <li><b>c</b> Any character represents itself apart from those mentioned below. Thus <b>c</b> matches the character \e c. <li><b>?</b> This matches any single character. It is the same as <b>.</b> in full regexps. <li><b>*</b> This matches zero or more of any characters. It is the same as <b>.*</b> in full regexps. <li><b>[...]</b> Sets of characters can be represented in square brackets the same as for full regexps. <!-- JASMIN: Are the character classes, \w, etc supported in wildcards? --> </ul> For example if we are in wildcard mode and have strings which contain filenames we could identify HTML files with <b>*.html</b>. This will match zero or more characters followed by a dot followed by 'h', 't', 'm' and 'l'. <a name="perl-users"><b>Notes for Perl Users</b></a> Most of the character class abbreviations supported by Perl are supported by QRegExp, see <a href="#characters-and-abbreviations-for-sets-of-characters"> characters and abbreviations for sets of characters</a>. QRegExp's quantifiers are the same as Perl's greedy quantifiers. Non-greedy matching cannot be applied to individual quantifiers, but can be applied to all the quantifiers in the pattern. For example, to match the Perl regex <b>ro+?m</b> requires: \code QRegExp rx( "ro+m" ); rx.setMinimal( TRUE ); \endcode The equivalent of Perl's <tt>/i</tt> option is setCaseSensitive(FALSE). Perl's <tt>/g</tt> option can be emulated using a <a href="#cap_in_a_loop">loop</a>. In QRegExp <b>.</b> matches any character, therefore all QRegExp regexps have the equivalent of Perl's <tt>/s</tt> option. QRegExp does not have an equivalent to Perl's <tt>/m</tt> option, but this can be emulated in various ways for example by splitting the input into lines or by looping with a regexp that searches for newlines. Because QRegExp is string oriented there are no \A, \Z or \z assertions. The \G assertion is not supported but can be emulated in a loop. Perl's $& is cap(0) or capturedTexts()[0]. There are no QRegExp equivalents for $`, $' or $+. $1, $2 etc correspond to cap(1) or capturedTexts()[1], cap(2) or capturedTexts()[2], etc. To substitute a pattern use QString::replace(). Perl's extended <tt>/x</tt> syntax is not supported, nor are regexp comments (?#comment) or directives, e.g. (?i). Both zero-width positive and zero-width negative lookahead assertions (?=pattern) and (?!pattern) are supported with the same syntax as Perl. Perl's lookbehind assertions, "independent" subexpressions and conditional expressions are not supported. Non-capturing parenthesis are also supported, with the same (?:pattern) syntax. See QStringList::split() and QStringList::join() for equivalents to Perl's split and join functions. Note: because C++ transforms \\'s they must be written \e twice in code, e.g. <b>\\</b><b>b</b> must be written <b>\\</b><b>\\</b><b>b</b>. <a name="code-examples"><b>Code Examples</b></a> \code - QRegExp rx( "^\\d\\d?$" ); // Match integers 0 to 99 - rx.search( "123" ); // Returns -1 (no match) - rx.search( "-6" ); // Returns -1 (no match) - rx.search( "6" ); // Returns 0 (matched as position 0) + QRegExp rx( "^\\d\\d?$" ); // Match integers 0 to 99 + rx.search( "123" ); // Returns -1 (no match) + rx.search( "-6" ); // Returns -1 (no match) + rx.search( "6" ); // Returns 0 (matched as position 0) \endcode The third string matches '<u>6</u>'. This is a simple validation regexp for integers in the range 0 to 99. \code - QRegExp rx( "^\\S+$" ); // Match strings which have no whitespace - rx.search( "Hello world" ); // Returns -1 (no match) - rx.search( "This_is-OK" ); // Returns 0 (matched at position 0) + QRegExp rx( "^\\S+$" ); // Match strings which have no whitespace + rx.search( "Hello world" ); // Returns -1 (no match) + rx.search( "This_is-OK" ); // Returns 0 (matched at position 0) \endcode The second string matches '<u>This_is-OK</u>'. We've used the character set abbreviation '\S' (non-whitespace) and the anchors to match strings which contain no whitespace. In the following example we match strings containing 'mail' or 'letter' or 'correspondence' but only match whole words i.e. not 'email' \code QRegExp rx( "\\b(mail|letter|correspondence)\\b" ); - rx.search( "I sent you an email" ); // Returns -1 (no match) + rx.search( "I sent you an email" ); // Returns -1 (no match) rx.search( "Please write the letter" ); // Returns 17 (matched at position 17) \endcode The second string matches "Please write the <u>letter</u>". The word 'letter' is also captured (because of the parenthesis). We can see what text we've captured like this: \code QString captured = rx.cap( 1 ); // captured contains "letter" \endcode This will capture the text from the first set of capturing parenthesis (counting capturing left parenthesis from left to right). The parenthesis are counted from 1 since cap( 0 ) is the whole matched regexp (equivalent to '&' in most regexp engines). \code - QRegExp rx( "&(?!amp;)" ); // Match ampersands but not & + QRegExp rx( "&(?!amp;)" ); // Match ampersands but not & QString line1 = "This & that"; line1.replace( rx, "&" ); // line1 == "This & that" QString line2 = "His & hers & theirs"; line2.replace( rx, "&" ); // line2 == "His & hers & theirs" \endcode Here we've passed the QRegExp to QString's replace() function to replace the matched text with new text. \code QString str = "One Eric another Eirik, and an Ericsson. How many Eiriks, Eric?"; - QRegExp rx( "\\b(Eric|Eirik)\\b" ); // Match Eric or Eirik + QRegExp rx( "\\b(Eric|Eirik)\\b" ); // Match Eric or Eirik int pos = 0; // Where we are in the string int count = 0; // How many Eric and Eirik's we've counted while ( pos >= 0 ) { - pos = rx.search( str, pos ); - if ( pos >= 0 ) { - pos++; // Move along in str - count++; // Count our Eric or Eirik - } + pos = rx.search( str, pos ); + if ( pos >= 0 ) { + pos++; // Move along in str + count++; // Count our Eric or Eirik + } } \endcode We've used the search() function to repeatedly match the regexp in the string. Note that instead of moving forward by one character at a time <tt>pos++</tt> we could have written <tt>pos += rx.matchedLength()</tt> to skip over the already matched string. The count will equal 3, matching 'One <u>Eric</u> another <u>Eirik</u>, and an Ericsson. How many Eiriks, <u>Eric</u>?'; it doesn't match 'Ericsson' or 'Eiriks' because they are not bounded by non-word boundaries. One common use of regexps is to split lines of delimited data into their component fields. \code str = "Trolltech AS\twww.trolltech.com\tNorway"; QString company, web, country; rx.setPattern( "^([^\t]+)\t([^\t]+)\t([^\t]+)$" ); if ( rx.search( str ) != -1 ) { - company = rx.cap( 1 ); - web = rx.cap( 2 ); - country = rx.cap( 3 ); + company = rx.cap( 1 ); + web = rx.cap( 2 ); + country = rx.cap( 3 ); } \endcode In this example our input lines have the format company name, web address and country. Unfortunately the regexp is rather long and not very versatile -- the code will break if we add any more fields. A simpler and better solution is to look for the separator, '\t' in this case, and take the surrounding text. The QStringList split() function can take a separator string or regexp as an argument and split a string accordingly. \code QStringList field = QStringList::split( "\t", str ); \endcode Here field[0] is the company, field[1] the web address and so on. To immitate the matching of a shell we can use wildcard mode. \code - QRegExp rx( "*.html" ); // Invalid regexp: * doesn't quantify anything - rx.setWildcard( TRUE ); // Now its a valid wildcard regexp - rx.search( "index.html" ); // Returns 0 (matched at position 0) - rx.search( "default.htm" ); // Returns -1 (no match) - rx.search( "readme.txt" ); // Returns -1 (no match) + QRegExp rx( "*.html" ); // Invalid regexp: * doesn't quantify anything + rx.setWildcard( TRUE ); // Now its a valid wildcard regexp + rx.search( "index.html" ); // Returns 0 (matched at position 0) + rx.search( "default.htm" ); // Returns -1 (no match) + rx.search( "readme.txt" ); // Returns -1 (no match) \endcode Wildcard matching can be convenient because of its simplicity, but any wildcard regex can be defined using full regexps, e.g. <b>.*\.html$</b>. Notice that we can't match both \c .html and \c .htm files with a wildcard unless we use <b>*.htm*</b> which will also match 'test.html.bak'. A full regexp gives us the precision we need, <b>.*\.html?$</b>. QRegExp can match case insensitively using setCaseSensitive(), and can use non-greedy matching, see setMinimal(). By default QRegExp uses full regexps but this can be changed with setWildcard(). Searching can be forward with search() or backward with searchRev(). Captured text can be accessed using capturedTexts() which returns a string list of all captured strings, or using cap() which returns the captured string for the given index. The pos() function takes a match index and returns the position in the string where the match was made (or -1 if there was no match). \sa QRegExpValidator QString QStringList <a name="member-function-documentation"/> */ static const int NumBadChars = 128;
