const getAttribute = require('xml-utils/src/get-attribute');
const xml = `<MDI key="INTERLEAVE">PIXEL</MDI>`;
const key = getAttribute(xml, 'key');
console.log(key);
// INTERLEAVE

find one tag by name

const findTagByName = require('xml-utils/src/find-tag-by-name');

const xml = `<Metadata domain="IMAGE_STRUCTURE"><MDI key="INTERLEAVE">PIXEL</MDI></Metadata>`
const tag = findTagByName(xml, 'MDI');
console.log(tag);

will output:

{
  outer: "<MDI key="INTERLEAVE">PIXEL</MDI>",
  inner: "PIXEL"
}

find multiple tags with the same name

const findTagsByName = require('xml-utils/src/find-tags-by-name');
const xml = `
    <Metadata>
      <MDI key="SourceBandIndex">1</MDI>
      <MDI key="STATISTICS_MAXIMUM">255</MDI>
      <MDI key="STATISTICS_MEAN">96.372431147996</MDI>
      <MDI key="STATISTICS_MINIMUM">0</MDI>
      <MDI key="STATISTICS_STDDEV">50.057898474622</MDI>
    </Metadata>
`;
const tags = findTagsByName(xml, 'MDI');
// will output an array of tags

find one tag by path

const findTagByPath = require('xml-utils/src/find-tag-by-path');
const xml = `
       <gmd:referenceSystemIdentifier>
         <gmd:RS_Identifier>
           <gmd:code>
             <gco:CharacterString>4326</gco:CharacterString>
           </gmd:code>
           <gmd:codeSpace>
             <gco:CharacterString>EPSG</gco:CharacterString>
           </gmd:codeSpace>
           <gmd:version>
             <gco:CharacterString>6.11</gco:CharacterString>
           </gmd:version>
         </gmd:RS_Identifier>
       </gmd:referenceSystemIdentifier>
       `;
const tag = findTagByPath(xml, ['gmd:RS_Identifier', 'gmd:code', 'gco:CharacterString']);

find multiple tags by path

To get an array of tags that follow a path:

const findTagsByPath = require('xml-utils/src/find-tags-by-path');
const tags = findTagByPath(xml, ['Metadata', 'MDI']);
// will output an array of tags
