I am having a problem with writing a parser in javascript. I have a xml file that has data the looks like this:

<patients>
<patient age="20">
<first_name>Keith</first_name>
<middle_name>John</middle_name>
<last_name>Griffey</last_name>
<ssn>267-81-8362</ssn>
<room>231</room>
<insurance>
<com_name>anthem</com_name>
<mem_id>KY</mem_id>
<group>none</group>
<phone_num>812-584-2162</phone_num>
</insurance>
</patient>
</patients>


My DTD file :

<!ELEMENT patients (patient+) >
<!ELEMENT patient (first_name,middle_name ,last_name,ssn,room,insurance )>
<!ELEMENT first_name (#PCDATA)>
<!ELEMENT middle_name (#PCDATA)>
<!ELEMENT last_name (#PCDATA)>
<!ELEMENT ssn (#PCDATA)>
<!ELEMENT room (#PCDATA)>
<!ELEMENT insurance (com_name,mem_id,group,phone_num)>
<!ELEMENT com_name (#PCDATA)>
<!ELEMENT mem_id (#PCDATA)>
<!ELEMENT group (#PCDATA)>
<!ELEMENT phone_num (#PCDATA)>


<!ATTLIST patient age CDATA #REQUIRED>


for some reason i can not access the data in insurance to parse the data. insurance has 4 subfields in it but im not sure how to access it. my JS code looks like this:

var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async="false";
xmlDoc.load("hospital2.xml");
var doc=xmlDoc.documentElement;

function testclick(field)
{
var row=field.rowIndex
xml_list.recordset.absoluteposition=row
td_first.innerHTML=xml_list.recordset("first_name")
td_middle.innerHTML=xml_list.recordset("middle_name")
td_last.innerHTML=xml_list.recordset("last_name")
td_ssn.innerHTML=xml_list.recordset("ssn")
td_age.innerHTML=xml_list.recordset("age")
td_room.innerHTML=xml_list.recordset("room")
//td_insurance.innerHTML=xml_list.recordset("insurance") // problem starts here
td_com_name.innerHTML.innerHTML=xml_list.recordset("com_name")
td_mem_id.innerHTML=xml_list.recordset("mem_id")
td_group.innerHTML=xml_list.recordset("group")
td_phone.innerHTML=xml_list.recordset("phone_num")
}

it will read the data all the way to the recordlist "room" but throws an error after that because of the subfields in insurance. can anyone help??

Looks like it would depend on what the recordset method does. It might be easier to work with IE's "data binding" mechanism, where tables are concerned.


BTW, I hope that information isn't from a confidential medical record... :eek:
