Question

我正在尝试匹配文本文件中的模式。只要图案位于一行内，它就可以很好地工作。但是，在某些情况下，模式可能会跨越两行。我有以下代码：

#indicate the Name pattern to R
name_pattern = '<nameOfIssuer>([^<]*)</nameOfIssuer>'

#Collect information that match the pattern that we are looking #
datalines = grep(name_pattern, thepage[1:length(thepage)], value = TRUE)

#We will use gregexpr and gsub to extract the information without the html tags
#create a function first
getexpr = function(s,g)substring(s,g,g+attr(g,'match.length')-1)
gg = gregexpr(name_pattern, datalines)
matches = mapply(getexpr, datalines, gg)
result = gsub(name_pattern, '\\1', matches)
result <- gsub("&amp;", "&", result)

names(result) = NULL

当文本为：

时效果很好

<nameOfIssuer>Posco ADR</nameOfIssuer>

如果文本如下所示，则不能播放：

<nameOfIssuer>Bank of
  America Corp</nameOfIssuer>

有人知道如何动态处理这两种情况吗？

全文如下：

Answer 1

假设您的文档中可能有多个个匹配<nameOfIssuer>的标签，并且您想匹配所有标签，那么我们可以尝试将grepexpr与{{1} }：

regmatches

Answer 2

使用Tim的解决方案以及粘贴粘贴的折叠选项，程序可以正常工作。代码如下：
