i have string of code come delineate attribute of feature name. how ever if feature null still add comma. how code ignore feature name not have value. <xsl:for-each select="feature"> <!-- output feature name (there may more 1 feature associated --> <!-- point) identify feature attrinbutes --> <!-- associated with. --> <xsl:text>,</xsl:text> <!-- comma separate feature name code or previous feature --> <xsl:variable name="featname" select="@name"/> <!-- feature name --> <xsl:for-each select="attribute"> <xsl:if test="position() &gt; 0"> <xsl:text>,</xsl:text> <!-- include comma if not first attribute --> </xsl:if> <!-- prefix each attribute name feature belongs followed ':' --> <xsl:if test="$includefieldnames = 'yes'">...

i new cordova plugin development stuff. want write plugin able open new android activty , showing advertisement. so followed simple tutorial here . works , expected. next step include android studio gradle project plugin. my first try: adding gradle project subfolder of cordova plugin , adding following line plugin.xml file: <framework src="libs/broper/build.gradle" custom="true" type="gradlereference" /> also tried: <framework src="libs/broper/app/build.gradle" custom="true" type="gradlereference" /> the graddle files recognised cordova. don't work. can't import classes of android studio project plugin java files. then better solution (i thought so) add aar instead. there don't have clue add aar in cordova plugin. so, question is: how add android atudio aroject (or library) cordova plugin right way? here's i've done use gradle reference cordova plugin, think might...

i wondering either possible in c++ run constructor overload within constructor. know possible using regular methods. tryng do: class foo { public: foo(); foo(int val); }; foo::foo() { foo(1); } foo:foo(int val) { std::cout << val; } this doesnt compile me. trying create 2 constructors 1 witch takes parameter , 1 sets default (the void one). aprichiate help. class foo { public: foo(); foo(int val); }; foo::foo() : foo(1) { } foo:foo(int val) { std::cout << val; }

i have data frame this lonship latship lonint latint -179.94 -38.05 1 128 -179.93 -32.54 1 123 -179.93 -32.19 1 122 -179.93 -31.83 1 122 -179.92 -33.97 1 124 -179.92 -33.61 1 124 what want associate @ each (ordered) pair (lonint,latint) number identify grid cell. e.g. lonship latship lonint latint cell -179.94 -38.05 1 128 1 -179.93 -32.54 1 123 2 -179.93 -32.19 1 122 3 -179.93 -31.83 1 122 3 -179.92 -33.97 1 124 4 -179.92 -33.61 1 124 4 note that, example (1, 2) != (2,1), i.e. must have 2 different cell number. can help? if want ordered pairs need first order multiple columns: dat<-dat[order(dat$lonint,dat$latint,decreasing=f),] then can use simple formula concatenate 2 values. example, if max(latint)<1000 can do: gridint=dat$lonint*1000+dat$latint edit: well, first order not needed formula because ordering fo...
