possible to read xml file in custom widget?
-
@Anduril I guess
XMLHttpRequestwon't support JAVA. if you want to read remote XML file you can use the following code,var myImports = new JavaImporter(java.io, java.lang, java.util, java.text); with(myImports) { var response = mcApi.http().get("http://www.plus2net.com/php_tutorial/file-xml-demo.xml"); if(response.responseCode == 200){ var xmlData = response.entity; // your code... } } -
Thanks a lot four your code, I will try to refine this and get it working. I will have a local xml file in future, but I think I will find a good tutorial for this in the web.

hi,
is it also possible to read a local xml file? And how can I access the different information in the file, are they transfered to the xmlData as options? So would this file:
<?xml version="1.0" encoding="UTF-8"?> <name id="1"> <first>John</first> <last>Doe</last> </name>be read as for example
xmlData.name.first -
-
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().getdoes 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)- ReturnsString- 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"?> <student> <details> <id>1</id> <name>John Deo</name> <class>Four</class> </details> <details> <id>2</id> <name>Max Ruin</name> <class>Three</class> </details> <details> <id>3</id> <name>Arnold</name> <class>Three</class> </details> <details> <id>4</id> <name>Krish Star</name> <class>Four</class> </details> <details> <id>5</id> <name>John Mike</name> <class>Four</class> </details> </student>- Read
student:/student
- Read
namewhereidis4:/student/details/id[text()='4']/../name//id[text()='4']/../name
- Read
classof 2nd element:/student/details[2]/class//details[2]/class
- Read
idwhere thenameisJohn Mike:/student/details/name[text()='John Mike']/../id//name[text()='John Mike']/../id
-
wow that's great... thanks a lot.

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/classfromThreetoFour.
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. -
@anduril I have removed the old method
readXmlByXpath. Introduced XmlApi class to address xml stuff.mcApi.xml().read(uri, xpath)- ReturnsStringuri- can be local disk path or http urlxpath- should be a valid xpath
mcApi.xml().readAsList(uri, xpath)- ReturnsList<Map<String, String>>uri- can be local disk path or http urlxpath- should be a valid xpath
mcApi.xml().update(uri, xpath, value)uri- should be local disk pathxpath- should be a valid xpathvalue- 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");
