System Information
OS X 10.9 on MacBook Pro 13 (Intel Iris graphics)

Blender Version
Broken: 2.74 (2015-Mar-31)

Problems importing VRML files generated by the popular chemistry tool JMol

Exact steps for others to reproduce the error

First problem:

1.) Start with the default empty project
2.) Try to import test.wrl.
3.) Obtain no error message, but also no imported objects. Viewing the file with e.g. "view3dscene" gives the correct result and no warnings.

First of all, please do not report several issue in a single thread, we want one report per issue (much easier to handle).

Split this one in two (#45203).

Issue is with long lines like this one:

 Transform{translation 1.262 1.293 .184 children DEF _0 Shape{geometry Sphere{radius 0.476} appearance  DEF _1 Appearance{material Material{diffuseColor .621 .313 .711 transparency 0}}}}

Current code would end up reading whole translation 1.262 1.293 .184 children DEF _0 Shape at once and miss the new child node defined at the end.

For now, solution is to separate each property (field in vrml slang) on a single line during our pre-process step. That way, fields implying a new node or more (like children one) are correctly handled, even if they do not explicitly have their - [ ] braces (this is valid vrml syntax, if MFNode field has a single node, - [ ] are not mandatory…).
