How can I find the item number?

Question

Good day everyone!
If I have a drop down list and want to find the number of the selected item, how do I work it out?
The boundItem method gives me the current data value, but I need the item number. The mission is to add instances to another drop down list with child nodes of the value chosen in the first drop down list.
I've tried out the currentRecordNumber property, but I can't make it work. In Adobe XML Form object Model Reference they puts up
xfa.dataWindow.currentRecordNumber
but without any further reference to the current dropdownlist in that code, I don't understand how it works.
Please help me out.
best regards,

Hi!<br /><br />Thank you for your response! <br />I still don't get it right though after trying different methods over and over again and I therefore have two questions.<br /><br />1) Why do you use the <i>getElement</i> method to get an attribute? It would make more sense to me if you suggested the <i>getAttribute</i> method instead. Now, I have been trying out some different combinations of these two methods with the @ symbol, but without success. The getAttribute is described both in this forum and in the Adobe XML Form Object Model 2.2 Reference, but always in combination with recordSet. The recordSet object is a part of the sourceSet model which is used in OLEDB connections. I don't use that and wonder if I could use the getAttribute solely on the dataValue itself. I.e.the loaded XML looks somewhat like this:<br /><cars><br /><carowner carproducer="Ford">Person A</carowner><br /><carowner carproducer="VW">Person B</carowner><br /><carowner carproducer="Lexus">Person C</carowner><br /><carowner carproducer="Ford">Person D</carowner><br /><carowner carproducer="Nissan">Person E</carowner><br /><carowner carproducer="Volvo">Person F</carowner><br /><carowner carproducer="VW">Person G</carowner><br /><carowner carproducer="Ford">Person H</carowner><br /></cars><br /><br />var persons = xfa.resolveNode("$data.car");<br /><br />for (counter=0; counter<a.length; counter++)<br />{<br /><br />if (persons.nodes.item(counter).getAttribute("carproducer").value=="Ford")<br />{<br /><br />listBox1.addItem(persons.nodes.item(counter).value;<br /><br />}<br /><br />};<br /><br />Certainly there would be several faults in the code above, but please comment the getAttribute part.<br /><br />2)<br />All this (the methodology above) is described in the Acrobat JavaScript Scripting Reference for Acrobat 7.0 in the chapter showing the XMLData object (page 639) using a applyXPath and parse. If I use copy&paste from this manual and insert as a function in a script object,it works just fine. Are there any tips on how I can make it work on the nodeList XFA object?<br />The following test is attached to the description of the applyXPath method:<br /><i>NOTE: An exception is thrown when the value of this parameter is a nodeList XFA object instead the root of an XML tree, as required.</i><br /><br />best regards, <br />Håkon
