Extracting XML elements with XML rules
XSLT often is used to extract a specific subset of data from an XML file. You can accomplish the same thing
using XML rules. The following sample script shows how to duplicate a set of sample XML elements and
move them to another position in the XML element hierarchy. Note that you must add the duplicated XML
elements at a point in the XML structure that will not be matched by the XML rule, or you run the risk of
creating an endless loop. For the complete script, see ExtractSubset.
main();
function main(){
if (app.documents.length != 0){
var myDocument = app.documents.item(0);
var myRuleSet = new Array (new ExtractVCO);
var myMarkupTag = myDocument.xmlTags.add("VCOs");
var myContainerElement =
myDocument.xmlElements.item(0).xmlElements.add(myMarkupTag);
with(myDocument){
var elements = xmlElements;
__processRuleSet(elements.item(0), myRuleSet);
}
}
else{
alert("No open document");
}
function ExtractVCO(){
var myNewElement;
this.name = "ExtractVCO";
this.xpath = "/devices/device/type";
this.apply = function(myElement, myRuleProcessor){
with(myElement){
if(myElement.texts.item(0).contents == "VCO"){
myNewElement = myElement.parent.duplicate();
myNewElement.move(LocationOptions.atEnd,
app.documents.item(0).xmlElements.item(0).xmlElements.item(-1));
}
}
return true;
}
}
