iandunn Posted October 4, 2005 Share Posted October 4, 2005 I'm using JavaScript to retrieve info from an XML file, but if any of the fields are empty I get this error: Error: xmlDocument.getElementsByTagName("address2Title")(0).firstChild has no propertiesSource File: http://localhost/contactManager/Line: 47Here's an example of the XML file:<contact> <id>2</id> <firstName>First Name</firstName> <lastName>Last Name</lastName> <address1Title>Home</address1Title> <address1>101 Blah St</address1> <city1>Dayton</city1> <state1>Ohio</state1> <zipCode1>45402</zipCode1> <address2Title/> <address2/> <city2/> <state2/> <zipCode2/> <homePhone>9375559407</homePhone> <cellPhone>9375556845</cellPhone> <workPhone/> <birthday>01311978</birthday></contact> And here's the relevant JS code document.getElementById("contactInfo").innerHTML = xmlDocument.getElementsByTagName('firstName').item(0).firstChild.nodeValue +xmlDocument.getElementsByTagName('lastName').item(0).firstChild.data +xmlDocument.getElementsByTagName('address1Title').item(0).firstChild.data +xmlDocument.getElementsByTagName('address1').item(0).firstChild.data +xmlDocument.getElementsByTagName('city1').item(0).firstChild.data +xmlDocument.getElementsByTagName('state1').item(0).firstChild.data +xmlDocument.getElementsByTagName('zipCode1').item(0).firstChild.data +xmlDocument.getElementsByTagName('address2Title')(0).firstChild.nodeValue +xmlDocument.getElementsByTagName('address2').item(0).firstChild.data +xmlDocument.getElementsByTagName('city2').item(0).firstChild.data +xmlDocument.getElementsByTagName('state2').item(0).firstChild.data +xmlDocument.getElementsByTagName('zipCode2').item(0).firstChild.data +xmlDocument.getElementsByTagName('homePhone').item(0).firstChild.data +xmlDocument.getElementsByTagName('cellPhone').item(0).firstChild.data +xmlDocument.getElementsByTagName('workPhone').item(0).firstChild.data +xmlDocument.getElementsByTagName('birthday').item(0).firstChild.data; Is there a way to access the field that won't cause an error if it's empty, or is there a way to check if it's empty before trying to use it?

Webworldx Posted October 7, 2005 Share Posted October 7, 2005 var fields = [ "firstName" , "lastName" , "addressTitle" , "address1" , "city1" ];var content = ""for(i = 0; i < fields.length; i++){ if(xmlDocument.getElementsByTagName(fields[i]).item(0).firstChild.data){ content += xmlDocument.getElementsByTagName(fields[i]).item(0).firstChild.data }}document.getElementById("contactInfo").innerHTML = content Something like that?
