xml - What is causing "junk after end of expression" error from xpath command? -


being far short of expert @ xml, i've been going through basic tutorials. there this one on xpath. luckily, linux setup has 'xpath' command works fine, until attributes.

xpath -e 'inventory/snack/chips@supplier'  lemonade2.xml

gives error

parse of expression inventory/snack/chips@supplier failed - junk after end of expression: @supplier @ /usr/share/perl5/xml/xpath/parser.pm line 127.

my lemonade2.xml copy-pasted straight site. xpath works fine without '@supplier'.

maybe there's subtle missing character or something, or i've fat-fingered xpath ruin somehow. maybe tutorial old , uses obsolete xpath syntax? nah, break lot of existing code, wouldn't it? interference bash syntax? doing wrong?

accessing attributes path step in xpath, you're missing slash in front of attribute.

xpath -e 'inventory/snack/chips/@supplier'  lemonade2.xml

is <inventory/> outermost element? might want declare root in front of it:

xpath -e '/inventory/snack/chips@supplier'  lemonade2.xml

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
