<!--- Verify first that your improvement is not already reported on GitHub -->
<!--- Also test if the latest release and devel branch are affected too -->

##### SUMMARY
<!--- Explain the problem briefly below, add suggestions to wording or structure -->

latest and devel documentation shows example to add escape characters for double quotes text. 
i.e. to bypass " with \\". But this needs not to be done anymore with respect to the latest ansible version (ex. 2.8.5v)

Current example : 
- name: Add several more beers to the 'beers' element and add them before the 'Rochefort 10' element
  xml:
    path: /foo/bar.xml
    xpath: '/business/beers/beer[text()=\\"Rochefort 10\\"]'
    insertbefore: yes
    add_children:
    - beer: Old Rasputin
    - beer: Old Motor Oil
    - beer: Old Curmudgeon

Should be : 
- name: Add several more beers to the 'beers' element and add them before the 'Rochefort 10' element
  xml:
    path: /foo/bar.xml
    xpath: '/business/beers/beer[text()="Rochefort 10"]'
    insertbefore: yes
    add_children:
    - beer: Old Rasputin
    - beer: Old Motor Oil
    - beer: Old Curmudgeon
