- Write A Gui Program That Will Parse An Xml File To Check Whether Each Start Tag Such As Name Has An End Tag Such As 1 (458.56 KiB) Viewed 22 times
Write a GUI program that will parse an XML file to check whether each start tag (such as <name>) has an end tag (such as </name>); empty element tags (such as <br/>, where you may assume that such tags have before >) should also be identified, but declaration tags (such as <?xml version="1.0" encoding="UTF-8"?>) can be ignored. You may assume that all the tags are all well-formed, and that there are no tags that are both end and empty element tags. Allow the user to select the file to be checked and use regular expressions to identify tags in the file (try to use just one regular expression to identify both start and end tags). Ensure that the program does not end abruptly if no file is selected, a blank file is selected, or no tags are found for displaying. You are required to use the QRegularExpression class (and not the older QRegExp class). Once the file has been checked, display the following (in order): Cases where there is a start tag with no end tag. Cases where there is an end tag with no start tag. All empty element tags. ● Tags may contain alphanumeric characters, underscores, or hyphens; you may assume that there are no spaces in the tags. You are not expected to ensure that the tags are correctly nested but are simply checking that each start tag has an end tag and vice versa. Use appropriate OOP design principles when designing your solution.
