Finding XML elements

As noted earlier, the subset of XPath supported by XML rules does not allow for searching the text
contents of XML elements. To get around this limitation, you can either use attributes to find the XML
elements you want or search the text of the matching XML elements. The following script shows how to
match XML elements using attributes. This script applies a color to the text of elements it finds, but a
practical script would do more. For the complete script, see FindXMLElementByAttribute.
main();
function main(){
if (app.documents.length != 0){
var myDocument = app.documents.item(0);
var myRuleSet = new Array(new AddAttribute);
with(myDocument){
}
//Now that the attributes have been added, find and format
//the XML element whose attribute content matches a specific string.
var myRuleSet = new Array(new FindAttribute);
with(myDocument){
}
}
else{
alert("No open document");
}
function AddAttribute(){
this.name = "AddAttribute";
this.xpath = "/devices/device/part_number";
this.apply = function(myElement, myRuleProcessor){
with(myElement){
if(myCounter % 2 == 0){
myElement.texts.item(0).fillColor =
app.documents.item(0).colors.item("ColorB");
}
myCounter++;
}
//Do not process the element with any further matching rules.
return true;
var elements = xmlElements;
__processRuleSet(elements.item(0), myRuleSet);
var elements = xmlElements;
__processRuleSet(elements.item(0), myRuleSet);
