handling xml in vbscript, new element causing problems -

i'm guessing pretty straightforward i'm not versed in handling xml data.

i have vbscript code processes xml data third party in format.

<data>     <thing1>some thing</thing1>     <thing2>some other thing</thing2>     <parameter>         <parametername>customthing1</paramtername>         <parametervalue>this data want</parametervalue>     </parameter> </data> 

previously, data came in thing1 or thing2. have had add custom field data, , third party sending in 'parameter' format.

i old data so: (objxmlrequest msxml2.domdocument object)

thing1 = objxmlrequest.documentelement.selectsinglenode("thing1").firstchild.nodevalue 

now need value customthing1, don't want pull 'parametervalue' because if add custom field in future problem. need make sure i'm getting paramtervalue parametername = customthing1. how that?

based on this: find parameter customthing1 parametername , access parametervalue:

dim objmsxml : set objmsxml = createobject("msxml2.domdocument") objmsxml.setproperty "selectionlanguage", "xpath" objmsxml.async = false objmsxml.load ".\38512955.xml"  if 0 = objmsxml.parseerror    dim sxpath : sxpath  = "/data/parameter[parametername=""customthing1""]/parametervalue"    dim ndx    : set ndx = objmsxml.selectsinglenode(sxpath)    if ndx nothing       wscript.echo sxpath, "failed"    else       wscript.echo ndx.tagname, ndx.text    end if else    wscript.echo objmsxml.parseerror.reason end if 

output:

cscript 38512955.vbs parametervalue data want
