Hi

This is a new thread as the previous one was for GZip specifically and i feel that this is a different topic / question. see Here for GZip post.

This question surrounds decompressing embedded text. I have done a lot of searching to find a solution any pretty much everything i find leans more toward an existing zip file that needs extracting. My instance is different in that, i have an XML file that inside contains a compressed text set for a 3D solid step file. So, what are my methods? Can i compress the text directly or do i need to get the text, save it as a zip then decompress it? Currently i have tried decompressing the text directly but i just get errors. The 2 errors i get are

  • Cannot find the magic GZip number
  • The input is not a valid Base-64 string

Im certain that the text is compressed as compared to orther compressed examples i have found, the text is in the same format. what im not certain is whether i need to contain the XML tag. I dont think i do. This is the tag

<STEPFile encoding="gzip;base64">

This is a truncated version of the file for text validation to a compressed file

So

Do i / can i decompress this directly as text to the step file or do i need to save the text as a zip, then extract it using a decompress method?


Thanks
