If this is html (which it look like it is) you should probably use an html parser. Package XML can do this
```
library(XML)
x <- "the text I need to extract
```
" xmlValue(getNodeSet(htmlParse(x), "//i")[[1]]) # [1] "the text I need to extract"
On an entire html document, you can use
```
doc <- htmlParse(x)
sapply(getNodeSet(doc, "//i"), xmlValue)
```
