xslt - Apply templates based on Input Parameter -


i in need apply templates according input parameter given.

input xml:

<?xml version="1.0"?> <chapter xmlns="http://www.w3.org/1998/math/mathml">     <section1>         <math><mtext>this section1 mtext</mtext></math>     </section1>     <section2>         <math><mtext>this section2 mtext</mtext></math>     </section2> </chapter>

if user gives xpath expression input parameter, particular xpath should selected , templates should applied.

for example, if user gives, "/chapter/section1/" input parameter required output is

<?xml version="1.0" encoding="utf-8"?><chapter> <section1> <math>~rom1~this section1 mtext</math> </section1> <section2> <math>~rom~this section2 mtext</math> </section2> </chapter>

if user gives, "/chapter/section1/" , "/chapter/section2" 2 input parameters then, output should be

<?xml version="1.0" encoding="utf-8"?><chapter> <section1> <math>~rom1~this section1 mtext</math> </section1> <section2> <math>~rom2~this section2 mtext</math> </section2> </chapter>

if user not give parameters, output should 

<?xml version="1.0" encoding="utf-8"?><chapter> <section1> <math>~rom~this section1 mtext</math> </section1> <section2> <math>~rom~this section2 mtext</math> </section2> </chapter>

i tried below xslt

<?xml version='1.0'?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform" xmlns:m="http://www.w3.org/1998/math/mathml"> <xsl:param name="xpath1"/> <xsl:param name="xpath2"/> <xsl:template match="@*|node()"><xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy></xsl:template> <xsl:template match="xpath1//mtext"><xsl:text>~rom1~</xsl:text><xsl:apply-templates/></xsl:template> <xsl:template match="xpath2//mtext"><xsl:text>~rom2~</xsl:text><xsl:apply-templates/></xsl:template> <xsl:template match="m:mtext"><xsl:text>~rom~</xsl:text><xsl:apply-templates/></xsl:template> </xsl:stylesheet>

if way not possible kindly suggest alternative achieve this

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).
