      well the way to access the data is (in my case) not important, I could also use a static parser. I want to open several xml files with all the same structure and extract the data to mycontroller variables. Those could be read and processed in a second step by another script.

        well I did also tried your example code and it seems mcApi.http().get does not work correctly...

        TypeError: mcApi.http is not a function in  at line number 4

          @anduril Can you post your complete code?

          I tested example code once again with SNAPSHOT build, seems everything ok.

            thanks @jkandasa, it was probably a problem solved with the most recent snapshot. I updated and it works now with the online xml.
            Using a local xml still yields an error, I think there is an error in my call...

            var myImports = new JavaImporter(java.io, java.lang, java.util, java.text);
            
            with(myImports) {
             var response = mcApi.http().get("c:/file-xml-demo.xml");
             if(response.responseCode == 200){
                var xmlData = response.entity;
             }
            }
            

            using [...]get("c:\file-[...] does not work either, so it's not a problem with slash and backslash.
            The html file only contains this:

            ${xmlData}
            

            Using the run nowoption I get this error:

            TypeError: Cannot get property "responseCode" of null in  at line number 5

              @anduril mcApi.http() used to access from network/internet. We cannot use it to access local disk files.

              To access local disk files, you can use the following program,

              var myImports = new JavaImporter(java.io, java.lang, java.util, java.text, org.apache.commons.io.FileUtils);
              
              with(myImports) {
               var xmlData = FileUtils.readFileToString(FileUtils.getFile("/tmp/file-xml-demo.xml"));
              }

                Thanks a lot, it works that way. Now my next problem is how to find specific information in this data. I could try to parse line by line, as I have a fixed structure. But maybe it would be easier to create a generic xml parsing mechanism. This would also allow for easier export to xml (my next step when reading works flawless).

                    @Anduril Feature available in SNAPSHOT version.

                    you can read xml content by xpath. To know more about xpath do google or have a look on https://www.w3schools.com/xml/xpath_intro.asp

                    Function/Method: mcApi.xml().read(uri, xpath) - Returns String

                    • uri - can be local disk path or http url
                    • xpath - should be a valid xpath
                    var myImports = new JavaImporter(java.io, java.lang, java.util, java.text);
                    
                    with(myImports) {
                     var myData = mcApi.xml().read("http://www.plus2net.com/php_tutorial/file-xml-demo.xml", "/student/details/id[text()='3']/../name");
                    }
                    

                    Some of xpath example:

                    XML content,

                    <?xml version="1.0" encoding="UTF-8"?>

                        This feature is great (at least for my usage). Is it also possible to update the values in the xml file? I don't mean adding new nodes or other fancy stuff, only updating for example /student/details/class from Threeto Four.
                        As far as I read the xpath is just a pointer in the tree of an xml, so there is no option to manipulate items. Maybe there is another function available to do this.

                          global:last-edited-by,

                          @anduril I have removed the old method readXmlByXpath. Introduced XmlApi class to address xml stuff.

                          • mcApi.xml().read(uri, xpath) - Returns String
                            • uri - can be local disk path or http url
                            • xpath - should be a valid xpath
                          • mcApi.xml().readAsList(uri, xpath) - Returns List<Map<String, String>>
                            • uri - can be local disk path or http url
                            • xpath - should be a valid xpath
                          • mcApi.xml().update(uri, xpath, value)
                            • uri - should be local disk path
                            • xpath - should be a valid xpath
                            • value - String value will be replaced on xpath

                          Is it also possible to update the values in the xml file? I don't mean adding new nodes or other fancy stuff, only updating for example /student/details/class from Three to Four.

                          Yes, now it is possible with,

                          mcApi.xml().update("/tmp/file-xml-demo.xml", "/student/details[1]/class", "Four");
                          

                          As far as I read the xpath is just a pointer in the tree of an xml, so there is no option to manipulate items. Maybe there is another function available to do this.

                          You can call readAsList,

                          var list = mcApi.xml().readAsList("/tmp/file-xml-demo.xml", "//id[text()='4']/..");
                          // get first result
                          var item = list.get(0);
                          
                          // get name, id, class
                          item.get("name");
                          item.get("id");
                          item.get("class");
