I have an xml like:

<?xml version="1.0" encoding="UTF-8"?>
<results>
    <result>
    <street>a</street>
    </result>

    <result>
    <street>b</street>
    </result>

    <result>
    <street>c</street>
    </result>
</results>

I want to obtain a list of string containing all the street values.

In my example it is:

[a,b,c]

With XPath I can write anything like:

//street

I tried anything like: 

XpathParser.INSTANCE.evaluate(xml, expression);

But I can only obtain a single string, not a list of strings.

Anybody have an idea?

  • @anubis you have to learn using Javadoc: https://docs.oracle.com/javase/8/docs/api/index.html?javax/xml/parsers/DocumentBuilder.html - as you can see, there are mutliple methods `parse`, one of them taking an `InputStream` as argument. Conversion of a `String` to `InputStream`? Well, use the search ... – UninformedUser Jun 07 '19 at 11:46
  • Here is the xpath that you can use `string-join(//result/street/text(),",")` – supputuri Jun 07 '19 at 12:53
