[英]Regex matching between two strings python
I am trying to match all ocurrences between two [Term]
's or a [Term]
and a [Typedef]
in a file cointaining something like this: 我正在尝试匹配文件中两个[Term]
或[Term]
和[Typedef]
Typedef [Term]
之间的所有匹配项:
remark: Includes Ontology(OntologyID(OntologyIRI(<http://purl.obolibrary.org/obo/go/never_in_taxon.owl>))) [Axioms: 18 Logical Axioms: 0]
ontology: go
[Term]

namespace: biological_process
def: "The distribution of mitochondria, including the mitochondrial genome, into daughter cells after mitosis or meiosis, mediated by interactions between mitochondria and the cytoskeleton." [GOC:mcc, PMID:10873824, PMID:11389764]

is_transitive: true
transitive_over: part_of ! part of
With: (?=\\[Term\\]\\s)[\\s\\S]*(?=\\s\\s\\[Term\\]\\s)
I'm only matching between the first [Term]
and the penultimate. 与: (?=\\[Term\\]\\s)[\\s\\S]*(?=\\s\\s\\[Term\\]\\s)
我只匹配第一个[Term]
和倒数第二个。
To match between the two, you can try this: 要在两者之间进行匹配,您可以尝试以下操作:
import re
s = "[Term] id: GO:0000001 name: mitochondrion inheritance namespace: biological_process def: "The distribution of mitochondria, including the mitochondrial genome, into daughter cells after mitosis or meiosis, mediated by interactions between mitochondria and the cytoskeleton." [GOC:mcc, PMID:10873824, PMID:11389764] synonym: "mitochondrial inheritance" EXACT [] is_a: GO:0048308 ! organelle inheritance is_a: GO:0048311 ! mitochondrion distribution" #etc
the_data = re.findall("\[Term\](.*?)\n\s\[Term\]|\[Term\](.*?)\n\s\[Typedef\]", s)
Final Output: 最终输出:
[(' id: GO:0000001 name: mitochondrion inheritance namespace: biological_process def: "The distribution of mitochondria, including the mitochondrial genome, into daughter cells after mitosis or meiosis, mediated by interactions between mitochondria and the cytoskeleton."

You may use 您可以使用
r'(?m)^\[Term].*(?:\r?\n(?!\[(?:Typedef|Term)]).*)*'
