[Issue] Add support for multiple space-separated CDATA sections in Magento\Framework\Xml\Parser

This issue is automatically created based on existing pull request: #26822: Add support for multiple space-separated CDATA sections in Magento\Framework\Xml\Parser

---

Description (*)

Our XML files sometimes contain multiple CDATA sections per node. The XML parser class provided by Magento in /lib/internal/Magento/Framework/Xml/Parser.php already supports consecutive CDATA sections like <![CDATA[One]]><![CDATA[Two]]><![CDATA[Three]]>, which is correctly parsed as OneTwoThree. However this returns wrong results for empty text nodes in-between, like for <![CDATA[One]]> <![CDATA[Two]]> <![CDATA[Three]]>. This pull request adds the support and a related unit test.

Related Pull Requests

The switch statement has been added in #681.

Fixed Issues (if relevant)

No separate issue created.

Manual testing scenarios (*)

Unit tests added as part of this pull request.

You can use the current 2.3.4 version for testing. The file in question /lib/internal/Magento/Framework/Xml/Parser.php is unchanged since August 2017.
