XML in Node.js (Using Javascript)

[coolszf5]

I've got simulated XML data stored the hard disk (called simmedData.xml). I've also got 'real' data (the 'real' data is dynamic) vended through a web endpoint (\[code\]http://localhost:8079/realData\[/code\]). The format of the XML documents are exactly the same, but I would like to 'merge' them into one endpoint available at \[code\]http://localhost:8080/mergedData\[/code\].I want to use node.js to host the mergedData endpoint -- Is there a simple way to merge these xml documents together when mergedData is requested?For example:simmedData.xml\[code\]<site:Tracks xmlns:site='http://mysite/site'> <site:track id='1' latitude='37.82091918923291' longitude='128.87375778822812' altitude='9753.6005859375' bearing='10.542624087704585' speedInKnots='454.6067199707031' /> <site:track id='2' latitude='37.45048387959727' longitude='129.49111126654887' altitude='9144.0' bearing='190.90400586790983' speedInKnots='436.89837646484375' /></site:Tracks>\[/code\]http://localhost:8079/realData\[code\]<site:Tracks xmlns:site='http://mysite/site'> <site:track id='1001' latitude='39.82093291' longitude='128.87375722812' altitude='9753.60375' bearing='10.542704585' speedInKnots='454.6707031' /> <site:track id='1002' latitude='39.387959727' longitude='129.4126654887' altitude='9144.0' bearing='90.90790983' speedInKnots='436.8984375' /> <site:track id='1003' latitude='40.82093291' longitude='138.87375722812' altitude='9753.5' bearing='10.542704585' speedInKnots='454.6707031' /> <site:track id='1004' latitude='40.387959727' longitude='139.4126654887' altitude='9124.0' bearing='90.90790983' speedInKnots='436.8984375' /></site:Tracks>\[/code\]http://localhost:8080/mergedData\[code\]<site:Tracks xmlns:site='http://mysite/site'> <site:track id='1' latitude='37.82091918923291' longitude='128.87375778822812' altitude='9753.6005859375' bearing='10.542624087704585' speedInKnots='454.6067199707031' /> <site:track id='2' latitude='37.45048387959727' longitude='129.49111126654887' altitude='9144.0' bearing='190.90400586790983' speedInKnots='436.89837646484375' /> <site:track id='1001' latitude='39.82093291' longitude='128.87375722812' altitude='9753.60375' bearing='10.542704585' speedInKnots='454.6707031' /> <site:track id='1002' latitude='39.387959727' longitude='129.4126654887' altitude='9144.0' bearing='90.90790983' speedInKnots='436.8984375' /> <site:track id='1003' latitude='40.82093291' longitude='138.87375722812' altitude='9753.5' bearing='10.542704585' speedInKnots='454.6707031' /> <site:track id='1004' latitude='40.387959727' longitude='139.4126654887' altitude='9124.0' bearing='90.90790983' speedInKnots='436.8984375' /></site:Tracks>\[/code\]
