Package Exports

xml-utils
xml-utils/src/find-tag-by-name
xml-utils/src/find-tag-by-path
xml-utils/src/get-attribute

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (xml-utils) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

const xml = `<MDI key="INTERLEAVE">PIXEL</MDI>`;
const key = getAttribute(xml, 'key');
console.log(key);
// INTERLEAVE

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/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/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']);

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