xml - How can I get child elements by element name with JavaScript? -


i have xml file many nodes this:

<map-item>             <location-name>u lot (pine sreet)</location-name>             <link>https://maps.google.com?daddr=pine+avenue+middletown+ct+06457</link>             <latitude>41.5501724</latitude>             <longitude>-72.6588056</longitude>             <icon-path>img/parking-icon.svg</icon-path>  </map-item>

i've looped through of map-item elements in xml file this:

 markers = xml.documentelement.getelementsbytagname("map-item");         (var = 0; < markers.length; i++) {               //do here each marker         }

but i'm having hard time figuring out how drill down , @ child elements inside of each map-item element, such location-name or icon-path. need in order grab values of child elements , them?

you can use getelementsbytagname again, on each marker. if xml valid , conforms schema, can expect there @ least 1 element of given name in <marker>.

var markers = xml.documentelement.getelementsbytagname("map-item"); (var = 0; < markers.length; i++) {     var marker = markers[i];     var locationname = marker.getelementsbytagname("location-name")[0].textcontent;     var iconpath = marker.getelementsbytagname("icon-path")[0].textcontent;     … }

if don't know how many child elements there in each <marker>, you'll have switch on .length of selected list or loop again.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
