Node-Libxml is a LibXML2 Node.js Wrapper

It can perform:

• Wellformed check & rerror report
• Validity against DTD/XSD(Schema) check,
• Get doctype informations (about dtd)
• GetXpath Values
• Load XMl from string or file path

Node-Libxml has nos any dependencies, it's fully bundled, so you can just use it as it comes :)

Works on : Linux, Osx & Windows (no 32bits, just 64 bits)

Node-libxml has been thought differently than libxmljs; whereas libxmljs can be use in commun uses, you can use node-libxml if:

• You wan to validate against DTD (libxmljs can't)
• You want a silent program if xml is not wellformed (node-libxml returns wellformed error in object; libxmljs throws)
• You want to do xml processing in parallel forks
• You want to load XML from file path OR string
• You want to validate against DTD / schema on multiple documents with just ONE dtd/schema loaded in memory (libxmljs loads it on each validation request), so it's clearly by far fastest!

  npm i node-libxml

  const Libxml = require('node-libxml');
  let libxml = new Libxml();

  let xmlIsWellformed = libxml.loadXml('path/to/xml');
  let xmlIsWellformedStr = libxml.loadXmlFromString('<name>test</name>');

  console.log(xmlIsWellformed);
  console.log(libxml.wellformedErrors);

  console.log(libxml.getDtd());

  libxml.loadDtds(['path/to/dtd1', 'path/to/dtd2']);
  let xmlIsValid = libxml.validateAgainstDtds();
  console.log(xmlIsValid);
  console.log(libxml.validationDtdErrors);

  //Get some xpaths;
  let aRandomPathBoolean = libxml.xpathSelect('boolean(//some/path'));
  let aRandomPathNumber = libxml.xpathSelect('number(//some/path'));
  let countSomeElements = libxml.xpathSelect('count(//some/path'));
  //... & all xpath could do I think

A function of libxml to validate against the previously loaded DTD(s) TAKE nothing & RETURN a string which is the name of the first dtd which has validated RETURN false if no dtd(s) have validate the xml RETURN null if no any dtd have been corectly loaded SET a an array 'validationDtdErrors' in libxml element if no dtd has validate

A function of libxml to evaluate the xpath on the previously loaded XML TAKE nothin & RETURN an object containing name,externalId & systemId

A function of libxml to evaluate the xpath on the previously loaded XML TAKE string & RETURN value depending on what you asked (number, boolean..) RETURN null if no match ex

Use those functions when you have finished jobs of elements, or before overwrite them. ex

A function of libxml to free XML memory file TAKE nothing & RETURN nothin FREE memory & clear 'wellformedErrors' property on libxml instance

A function of libxml to free all the Schema in memory TAKE nothing & RETURN nothin FREE memory & clear 'schemasLoadedErrors' property on libxml instance FREE memory & clear 'validationSchemaErrors' property on libxml instance

A function of libxml to free all the memory taken by libxml2 TAKE nothing & RETURN nothin free all memory in all instance in all fork using by libxml.

• npm i
• then move the build-tmp-napi-*{anyversionyougot} as -> mv build-tmp-napi-v7 build (for the moment I did not found how to build directly to buiuld forlder with pre-gyp for n-api)
• npm test should pass 😎

Travis & appveyor cannot be used anymore with n-api because auto-publish from node-pre-gyp-github not working anymore + we have now n release for one node version
