I have an rdocx and I want to manipulate something in the xml code. That’s my document:

library(officer)

doc <- read_docx() %>%
  body_add_par("centered text", style = "centered") %>%
  slip_in_seqfield("STYLEREF 1 \\s") %>% 
  slip_in_text("\u2011") %>% 
  slip_in_seqfield(sprintf("SEQ %s \\* ARABIC \\s 1", "Table")) %>% 
  slip_in_text(str_c(": ", "My Caption")) %>% 
  body_bookmark("my_bookmark")

With doc$doc_obj$get() I can get the xml code with classes xml_document and xml_node. Now I want to replace some code, in detail I want the part with w:bookmarkEnd to appear later so the bookmarked part gets bigger. How can I achieve this? If I could achieve this with str_replace it would be awesome.
