Extract strings from one field

Use the grok filter. I'm not 100% sure what result you expect from the example input string, but if you want the text inside the two single-quoted strings the following should work:

grok {
  match => [
    "name-of-field",
    "@name='(?<name1>[^']+)'.*@name='(?<name2>[^']+)'"
  ]
]

If the single-quoted strings themselves can contain single quotes that are escaped somehow it'll take some more care.
