All of the other posts utilize parsing a simple XML and I need to see how to parse sub levels.
What others post...
<book>
<booktitle>something</booktitle>
<author>someone</author>
</book>
easy enough... but this is what I am dealing with and I need to start at cookbook...
<cookbook>
<bookid>
<booktitle>something</booktitle>
<author>someone</author>
</bookid>
<bookid>
<booktitle>something</booktitle>
<author>someone</author>
</bookid>
</cookbook>
In Powershell you can dig down by (book.bookid.booktitle) but I am not seeing this in Javascript. Another thing is that the id's , remain the same for each book but I need the name of each book.
var parser = new DOMParser();
var xmlDoc = parser.parseFromString(book, "text/xml");
var first = xmlDoc.getElementsByTagName("cookbook")[0].childNodes[0].nodeValue;
I need the cookbook>bookid>booktitle> for each book. I have tried setting the values for the node and child node but it never shows a returned value just blank or null. Again all the posts I have sen on here deal with one level not three deep and that is what is throwing me off.
This site had good info but again one level... https://developer.mozilla.org/en-US/docs/Web/Guide/Parsing_and_serializing_XML
Let me be clear on something. The xml I am parsing has the booktitle listed in other locations under other nested groups, say dogbook>bookid>booktitle. I want this group cookbook>bookid>booktitle> as the other titles are not wanted so searching for booktitle will return both cook and dog. Forgot that major important part duh...
EDIT to illustrate looping through books below:
You can use jQuery in the browser, or cheerio (a subset of jQuery built for the server, https://www.npmjs.com/package/cheerio ) in NodeJS to parse XML easily. It might take a little time to learn the API to descend the XML doc and/or loop through elements, but it's pretty straightforward and easy to use.
// if jQuery or cheerio is bound as the `$` variable
const myXml = `<books>
<cookbook>
<bookid>
<booktitle>My Cookbook 1</booktitle>
<author>someone1</author>
</bookid>
<bookid>
<booktitle>My Cookbook 2</booktitle>
<author>someone</author>
</bookid>
<bookid>
<booktitle>My Cookbook 3</booktitle>
<author>someone</author>
</bookid>
</cookbook>
<dogbook>
<bookid>
<booktitle>My Dogbook 1</booktitle>
<author>someone</author>
</bookid>
<bookid>
<booktitle>My Dogbook 2</booktitle>
<author>someone</author>
</bookid>
</dogbook>
</books>`
const $myXml = $( $.parseXML(myXml) )
$firstCookBook = $myXml.find('cookbook').find('bookid').first()
$firstCookBook.children('booktitle').text()
// 'My Cookbook 1'
$firstCookBook.children('author').text()
// 'someone1'
// looping through all cookbook titles at books > cookbook > bookid > booktitle
$myXml.children('books').children('cookbook').each(function(index) {
console.log($( this ).find('booktitle').text())
// My Cookbook 1
// My Cookbook 2
// My Cookbook 3
})
var book = `<cookbook>
<bookid>
<booktitle>something delicious</booktitle>
<author>someone</author>
</bookid>
<bookid>
<booktitle>something else delicious</booktitle>
<author>someone</author>
</bookid>
</cookbook>`;
var parser = new DOMParser();
var xmlDoc = parser.parseFromString(book, "text/xml");
var first = xmlDoc.getElementsByTagName("booktitle")[0].childNodes[0].nodeValue;
console.log(first);
This prints 'something delicious' to the console. Javascript doesn't like multi-line variables either put the entire string on one line or use back tick (`).
