Parse Wikipedia Infobox with Go? - regex

Question

I am trying to parse the Infobox for some wikipedia articles and cannot seem to figure it out. I have downloaded the files and for Albert Einstein and my attempt to parse the Infobox looks like this:
package main
import (
"log"
"regexp"
)
func main() {
st := `{{redirect|Einstein|other uses|Albert Einstein (disambiguation)|and|Einstein (disambiguation)}}
{{pp-semi-indef}}
{{pp-move-indef}}
{{Good article}}

}
I am trying to put each of the items from the infobox into a struct or a map:
m["name"] = "Albert Einstein"
m["image"] = "Einstein...."
...
...
m["death_date"] = "{{Death date and age|df=yes|1955|4|18|1879|3|14}}"
...
...
I can't even seem to isolate the infobox. I get:
[[{{Infobox scientist
| name = Albert Einstein
| image = Einstein 1921 by F Schmutzer - restoration.jpg
| caption = Albert Einstein in 1921
| birth_date = {{Birth date|df=yes|1879|3|14}}]]
The Albert Einstein entry in the API can be found at:
https://en.wikipedia.org/w/api.php?action=query&titles=Albert%20Einstein&prop=revisions&rvprop=content&format=json
EDIT:
Based on the accepted answer to this question the I tried the following regex:
(?=\{Infobox)(\{([^{}]|(?1))*\})
but get:
panic: regexp: Compile(`(?=\{Infobox)(\{([^{}]|(?1))*\})`): error parsing regexp: invalid or unsupported Perl syntax: `(?=`
EDIT #2:
If there's a way to extract the information via their API then I'll take that....I've been reading through the docs and can't find it.

Answer 1

I made a regex that might work for you:
^\s*\|\s*([^\s]+)\s*=\s*(\{\{Plainlist\|(?:\n\s*\*.*)*|.*)
Explanation
This part: ^\s*\|\s*([^\s]+)\s*=\s* matches the start of lines like:
| <the_label> =
Continuing on the same line, this part: (\{\{Plainlist\|(?:\n\s*\*.*)*|.*) will match lists:
{{Plainlist|
* [[Ernst G. Straus]]
* [[Nathan Rosen]]
* [[Leó Szilárd]]
(Note that it may omit the final }}. Oh well.)
If there is no list, it matches until the end of the line.
