From 32c65970263c65022f5278b568c07b63c3d5d64b Mon Sep 17 00:00:00 2001 From: Adrian Kummerlaender Date: Sun, 15 Jun 2014 15:14:46 +0200 Subject: Merged "read-xml-file" and "read-file" into "read-file" * FunctionReadFile is now able to distinguish between XML files and plain text files ** it selects the appropriate course of action automatically ** reading the file as XML into the DOM or reading it as a string * the current selection criteria is the file extension ** I am thinking about trying to import every file into the DOM and using the result state of that action as selection criteria * Updated README.md and test cases accordingly --- src/function/read_file.cc | 53 ++++++++++++++++++++++++-- src/function/read_xml_file.cc | 86 ------------------------------------------- src/function/read_xml_file.h | 27 -------------- 3 files changed, 49 insertions(+), 117 deletions(-) delete mode 100644 src/function/read_xml_file.cc delete mode 100644 src/function/read_xml_file.h (limited to 'src/function') diff --git a/src/function/read_file.cc b/src/function/read_file.cc index 22e96d7..7603ad1 100644 --- a/src/function/read_file.cc +++ b/src/function/read_file.cc @@ -3,6 +3,8 @@ #include #include #include +#include +#include #include "boost/filesystem/fstream.hpp" @@ -11,7 +13,28 @@ namespace { -inline std::string readFile(const boost::filesystem::path& filePath) { +inline bool isXmlFile(const boost::filesystem::path& filePath) { + return filePath.extension() == ".xml";
