Something like this might work

//string ends on the first line that doesnt start with a "
foo( @"<?xml version="1.0"?>
       "<catalog>
       "   <book id="bk101" empty="">
       "       <author>\(author)</author>
       "       <title>XML Developer's Guide</title>
       "       <genre>Computer</genre>
       "       <price>44.95</price>
       "       <publish_date>2000-10-01</publish_date>
       "       <description>An in-depth look at creating applications with    XML.</description>
       "   </book>
       "</catalog>\n
    )

//additionally using a +" could be used to indicate a line break
foo( @"<?xml version="1.0"?>
      +"<catalog>
      +"   <book id="bk101" empty="">
      +"       <author>\(author)</author>
      +"       <title>XML Developer's Guide</title>
      +"       <genre>Computer</genre>
      +"       <price>44.95</price>
      +"       <publish_date>2000-10-01</publish_date>
      +"       <description>An in-depth look at creating applications with    XML.</description>
      +"   </book>
      +"</catalog>\n
    )
