# Visual Studio Projects
Must specify the namespace. Tidier to predifine it.

```
# -N: predefine namespace
xmlstarlet sel -N _=http://schemas.microsoft.com/developer/msbuild/2003 "//_:AdditionalLibraryDirectories" $PROJECT_FILE
```

## Delete Project References

```
# -L: inplace
# -d: delete nodes where the @Include contains $dep
dep=$1
xmlstarlet ed -L -N _=http://schemas.microsoft.com/developer/msbuild/2003 -d "//_:ProjectReference[contains(@Include,\"${dep}\")]" $PROJECT_FILE
```

## Fix projects that don't inherit from parent

```
# -u: update the element
# -x: update with expression
xmlstarlet ed -P -L -N _=http://schemas.microsoft.com/developer/msbuild/2003 \
    -u "//_:AdditionalIncludeDirectories[not(contains(.,\"%(AdditionalIncludeDirectories)\"))]" \
    -x "concat(.,\"%(AdditionalIncludeDirectories)\",';')" \
    -u "//_:AdditionalLibraryDirectories[not(contains(.,\"%(AdditionalLibraryDirectories)\"))]" \
    -x "concat(.,\"%(AdditionalLibraryDirectories)\",';')" \
    $*
```
