Groovy XMLSlurper Parse Values. Import groovy.xml.XmlUtil def serverList = new XmlSlurper().parse. Parse UTF-8 xml file with XmlSlurper. GetAbsolutePath()); return parse(input); }. I stepped through the SAX code but couldn't see the InputSource being closed so XmlSlurper is leaking file descriptors.
I am working on a groovy xml exercise & as per the problem, i need to write 2 methods: readFileContent(fileName) - This method is used to read the content from file(xml file) and return that file's content as string. LoadStudents(xmlString) - This method is used to generate the student list using the parameterized xml string(Please parse that xml string(use xmlSlurper) and create the student object and add to the studentList). I tried using xmlparser.parse(fileName) to create my xmlString, and then used xmlSlurper.parseText in loadStudent method. However, getting content is not allowed prolong error.
Here's my code: def xmlString = new XmlParser().parse(fileName) def students = new XmlSlurper().parseText(xmlString) here's xml: 1 1225 Madison 3 4152 Paul 5 1785 Sam 2 4158 Jason 4 1674 Harry Note: i know i can just directly parse the file in xmlSlurper & it works fine. However, this is online exercise & needs to be done using both methods. Thanks in advance.
In this blog I'm going to give a brief description of XMLParser and XMLSlurper and point out the similarities and differences between then with the help of Code Samples. XMLParser: 1.
XMLParser loads the XML document and then converts it into XML DOM(Document Object Model) object. XML DOM contains the functions for insert, delete, update and traversing of XML tree nodes. The code for XMLParser resides in groovy.util(). It can directly work on File objects and on other input sources returning groovy.util.node object.
XMLSlurper: 1. Groovy has in built XMLSlurper thus adding lot more functionality than the DOM Parser. Using less memory and less CPU power than XMLParser are XMLSlurper's main advantage. It Returns GPathResult. Similarities between XMLParser and XMLSlurper: 1.
Both reside in package groovy.util(). Both share same constructor parameters. The result of both XMLParser and XMLSlurper is either Node (XMLParser) or GPathResult (XMLSlurper). Node as well as GPathresult's Objects access both child element and attribute as they were properties of current object. Differences Between XMLParser and XMLSlurper 1. The big difference is that the Parser creates something similar to a DOM, while Slurper tries to create structures only if really needed(On Demand), hence uses the lazily evaluated paths. Parser structure is evaluated only once, the Slurper paths may be evaluated on demand.
Slurper's On Demand evaluation is 'more memory efficient but slower' which depends on the paths/requests made. XMLParser will always evaluate the whole of the XML, thus creating lot of objects, spending memory and computing power Whereas, XMLSlurper will evaluate lazily/onDemand, creating less objects, thereby saving a lot on the memory & CPU power.

In the case where all parts of the documents are needed, XMLParser would be a better choice, because even a Slurper would also create atleast as many objects as the parser would. XMLParser stores intermediate results after parsing documents, whereas, XMLSlurper does not stores internal results after processing XML documents.
Now we'll Parse the XML data from the file, Authors.xml, using both XMLParser and XMLSlurper.
