expression régulière findall

Version imprimable

Bonjour,

j'essaye désespérément de parser le texte suivant. Mon but est de faire en sorte que chaque élément entre {{ }} soit un élément d'une liste.

J'utilise pour cela la fonction findall mais sans succès.

Code:

re.findall("{{ ?.*|\s* ?}}",snp_page)

Merci d'avance pour votre aide.

Le texte à parser.

This SNP, a variant in the [[BRCA1]] gene, is 1 of 25 SNPs reported to represent independently minor, but cumulatively significant, increased risk for [[breast cancer]]. {{PMID|17341484}}

For details of all 25 SNPs in this group, along with the two methods used to calculate overall risk estimates for [[breast cancer]], refer to the SNPedia [[breast cancer]] entry.

For this particular SNP, the risk (minor) allele is (G).
