+### Condition deployment on package.xml and destructiveChange content

+SGD does not always generate content in the package.xml (or destructiveChanges.xml). Sometimes the commit range contains changes only within files to ignore (using .sgdignore and `--i` parameter).
+[Deploying empty package.xml can lead to deployment errors.](https://github.com/scolladon/sfdx-git-delta/issues/249)
+To avoid starting a failing deployment, test files content before execution:

+# run deploy command only if the generated package contains metadata
+if grep -q '<types>' ./package/package.xml ; then
