title: Please help me to split the complex header string into items
body: <p>Please help me to use Python regular expressions to split this header into the items</p>
  <pre><code>TITLE=&quot;D:\Experiments2021\iai_0107_\exp1_\Analysis\exp1_006014.T000.D000.P001.H000.L.vec&quot; VARIABLES=&quot;X mm&quot;, &quot;Y mm&quot;, &quot;U m/s&quot;, &quot;V m/s&quot;, &quot;CHC&quot;, DATASETAUXDATA Application=&quot;PIV&quot; DATASETAUXDATA SourceImageWidth=&quot;4008&quot; DATASETAUXDATA SourceImageHeight=&quot;2672&quot; DATASETAUXDATA MicrometersPerPixelX=&quot;85.809998&quot; DATASETAUXDATA MicrometersPerPixelY=&quot;85.809998&quot; DATASETAUXDATA LengthUnit=&quot;mm&quot; DATASETAUXDATA OriginInImageX=&quot;0.000000&quot; DATASETAUXDATA OriginInImageY=&quot;0.000000&quot; DATASETAUXDATA MicrosecondsPerDeltaT=&quot;50.000000&quot; DATASETAUXDATA TimeUnit=&quot;ms&quot; DATASETAUXDATA SecondaryPeakNumber=&quot;0&quot; DATASETAUXDATA DewarpedImageSource=&quot;0&quot; ZONE I=124, J=82, F=POINT
  </code></pre>
  <p>I cannot figure out how to separate the repeated pattern of the type:</p>
  <pre><code>DATASETAUXDATA MicrosecondsPerDeltaT=&quot;50.000000&quot; DATASETAUXDATA TimeUnit=&quot;ms
  </code></pre>
  <p>into:</p>
  <pre><code>header = {'MicrosecondsPerDeltaT':50.0000, 'TimeUnit':'ms', ...}
  </code></pre>
  <p>and so on.</p>
  <p>Thanks in advance,
  Alex</p>
