How to merge all paths in inkscape and then export correctly?

Question

inkscape

I have an icon:

<?xml version="1.0" encoding="utf-8"?>
<!-- Generator: Adobe Illustrator 22.1.0, SVG Export Plug-In . SVG Version: 6.00 Build 0)  -->
<svg version="1.1" id="Capa_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
   viewBox="0 0 30 30" style="enable-background:new 0 0 30 30;" xml:space="preserve">
<style type="text/css">
  .st0{fill:none;stroke:#FFFFFF;stroke-linecap:round;stroke-linejoin:round;stroke-miterlimit:10;}
</style>
<g>
  <rect x="3.4" y="3.1" class="st0" width="24" height="24"/>
  <line class="st0" x1="15.4" y1="3.4" x2="15.4" y2="27.1"/>
  <line class="st0" x1="3.6" y1="15.3" x2="27.3" y2="15.3"/>
  <g>
    <line class="st0" x1="9.6" y1="6.2" x2="9.6" y2="12.2"/>
    <line class="st0" x1="6.6" y1="9.2" x2="12.6" y2="9.2"/>
  </g>
  <g>
    <line class="st0" x1="23.5" y1="19.1" x2="19.2" y2="23.4"/>
    <line class="st0" x1="19.2" y1="19.1" x2="23.5" y2="23.4"/>
  </g>
  <g>
    <line class="st0" x1="18.3" y1="9.2" x2="24.3" y2="9.2"/>
  </g>
  <g>
    <g>
      <line class="st0" x1="6.6" y1="19.7" x2="12.6" y2="19.7"/>
    </g>
    <g>
      <line class="st0" x1="6.6" y1="22.7" x2="12.6" y2="22.7"/>
    </g>
  </g>
</g>
</svg>

I can't add styles with CSS.
You need to get the view icon:

   style="enable-background:new 0 0 26 26;" xml:space="preserve">
<style type="text/css">
  .st0{fill-rule:evenodd;clip-rule:evenodd;fill:#E9AB00;}
</style>

I suspect the icon is not exported correctly.
I opened it in Inkscape and saw that its paths were not merged.

We need to merge the paths and save to get the result, like the second icon.
I combined through the path -> merge Ctrl + K , saved, but the result of the image code did not change.

Answer 1

The problem is that all the lines in your icon are line objects, not closed paths. You first need to turn them all into paths via Path -> Stroke to Path , then make the intersection of those paths that really intersect through Path -> Union , and then do Path -> Combine .
