<title><![CDATA[Endeavour Journal of Sir Joseph Banks from 25 August 1768-12 July 1771, The by Joseph Banks (1743 - 1820)]]></title>
<description><![CDATA[In this Journal, Joseph Banks records almost daily observations of the journey of the ship the Endeavour on the first of James Cook’s voyages to the Pacific during the years 1768-1771. There are also more detailed accounts of the events, people, flora, fauna and geology of the places (except Brazil) where they landed. They landed at Brazil, Tahiti, New Zealand, Australia, Batavia, Cape Town and St. Helena.
Joseph Banks was one of the naturalists on the Endeavour, appointed by the Royal Society. The joint Royal Society, Royal Navy journey of the Endeavour was overtly a scientific expedition with the stated purpose of observing the transit of Venus from Tahiti. The other purpose of the journey was to attempt the discovery of the postulated Southern Continent (Terra Australis). In addition to himself, Banks funded the inclusion on the voyage of two other naturalists (Solander and Spöring) and two artists (Parkinson and Buchan).
Joseph Banks became famous upon the return to Britain of the Endeavour and went on to be a highly influential person in Britain. Banks was President of the British Royal Society for more than 40 years; and was a strong advocate for the settlement of New South Wales as a convict settlement. Along with James Cook, he was responsible for representing the Australian continent as terra nullius (“nobody’s land”) even though he observed the occupation of the land by the indigenous Australians, which misrepresentation contributed to the colonization of Australia by the British. Now, 250 years after the Endeavour's voyage, controversy and the voices of indigenous people are leading to a reassessment of the effects of James Cook’s voyages and the colonial legacy of Australia and New Zealand.

<title><![CDATA[Chapters on Evolution by Andrew Wilson (1852 - 1912)]]></title>
<description><![CDATA[Dr. Andrew Wilson FRSE was a Scottish physiologist and zoologist and lecturer in zoology and comparative anatomy at the University of Edinburgh and the Royal College of Surgeons of Edinburgh in the late 19th and early 20th century. In the preface of this book, he writes: "...the chief aim of the work is to present in a popular and readily understood form, the chief evidences of the evolution of living beings. In this view, whilst I have been content to assume the reality of that process, I have also endeavoured to marshal the more prominent facts of zoology and botany, which serve to prove that evolution, broadly considered is not merely a name for an unknown tendency in nature, but is an actual factor in the work of moulding the life with which the universe teems." - Summary by J. M. Smallheer]]></description>

<title><![CDATA[Green Valley by Katharine Yirsa Reynolds (1883 - ?)]]></title>
<description><![CDATA["Traveling men have a poor opinion of it. Ministers of the gospel have been known to despair of it. Socially ambitious matrons move out of it, or, if that is not possible, despise it. Real estate men can not get rich in it. And humorless folk sometimes have a hard, sad time of it in Green Valley". This is an authentic novel about a small town in the USA. A book about what people tell and don't tell, loves and losses, and the importance of community. Community life which did not go away. - Summary by Stav Nisser ]]></description>

<title><![CDATA[Weltfreund, Der by Franz Werfel (1890 - 1945)]]></title>
<description><![CDATA[»Mein einziger Wunsch ist, dir, o Mensch, verwandt zu sein!« (aus dem Gedicht "An den Leser")<br>
Dieses könnte als Motto dem Gedichtband vorangestellt sein.<br>
In diesen frühen Gedichten kommt Werfels zutiefst humane Weltsicht zum Ausdruck. Oft auch mit einem leichten Augenzwinkern, wenn es um seine eigene Befindlichkeit geht und immer mit dem Blick auf die kleinen Dinge im Leben, die so wichtig sein können. (Zusammenfassung von seito)]]></description>

(RSS feed courtesy of https://librivox.org/pages/librivox-feeds/)
We have the htmlTxt string which has the RSS feed content.
And we create the domParser object with the DOMParser constructor.
Next, we call parseFromString with htmlTxt and 'text/html' to parse the text as HTML.
Then we get all the item noes with doc.querySelectorAll .
And then we call querySelector on item with 'title' to get the title element inside each item element.
The textContent property gets the text content of the title element.
Now we should get:
