Hi, i have realized the snapshot is not visible in below mail. *my objective* to set comments for each parameter name like , clock_masters and all given below. Please find the code snippet. while (curr1 != end1) // iterate second level map { // LOG("Section name [%s] : Parameter name and value are [%s] --> // [%s]\n",curr->second.c_str(),curr1->first.c_str(),curr1->second.c_str()); ptParamVal.put("<xmlcomment>", "some comment"); ptParamVal.put((curr1->first).c_str(), (curr1->second).c_str()); curr1++; } ----------------------------------------------------------------------------------------------------------------------------------- //xml file generated is given below. ----------------------------------------------------------------------------------------------------------------------------------- <?xml version="1.0" encoding="utf-8"?> <profibusunits> <pb-atpcu-r4> <!--some comment--> 2 0 <host>192.168.2.10</host> 2 10045 <name>atpcu.r4</name> <nidstm>254</nidstm> <port>0</port> <profibus>0</profibus> 10045 3 RSPLServerEth_5_2_3 </pb-atpcu-r4> <pb-jru> <!--some comment--> 3 0 <host>localhost</host> 3 0 <name>jru</name> <nidstm>254</nidstm> <port>5502</port> <profibus>0</profibus> 0 3 RSPLServerEth_5_2_3 </pb-jru> Thanks & Regards Neelam +91-9871541627 On Mon, May 14, 2018 at 10:37 AM, neelam baliyan wrote:

Hi Daniel,

Thanks for you reply.

i tried to apply <xmlcomment> in my section of code, but it is only putting comment inside a section. i need to give comments on each and every node . Please see the snapshot code and generated xml file, its only setting xml comments of each section like section pb-atpcu-r4, but i need to set xml comments for each node. *my objective* to set comments for , clock_masters and all given below. Please see if you can help me in that.

Thanks & Regards Neelam +91-9871541627

according to the doc:

https://www.boost.org/doc/libs/1_67_0/doc/html/property_tree /parsers.html#property_tree.parsers.xml_parser

*XML comments are stored in nodes named <xmlcomment>, unless comment ignoring is enabled via the flags.* so you probably have to do something like:

Pt.put<String> ("Root.<xmlcomment>", "some comment");

I think that is the way to add comments.

Hi All,

I have read and store my complete configuration file in to boost property tree, now I want to export it to a xml file which i can do via function write_xml().

I wanted to add some comments inside my exported xml file.

Please help me to know, how to add comments inside xml file while exporting data from boost property tree.

Thanks & Regards Neelam
