dxml.parser is a streaming XML parser. The documentation at
http://jmdavisprog.com/docs/dxml/0.4.0/dxml_parser.html has a
link to more information about this at the top, behind 'StAX'.
Thus, when you're mapping over `xml`, you're not getting
`<a>some text</a>` at a time, but `<a>`, `some text`, and
`</a>` separately, as they're parsed. The `<a>` there is an
`elementStart` which lacks a `text`, hence the error.
Here's a script:
```d
#! /usr/bin/env dub
/++ dub.sdl:
dependency "dxml" version="0.4.0"
stringImportPaths "."
+/
import dxml.parser;
import std;
enum text = import(__FILE__)
.splitLines
.find("__EOF__")
.drop(1)
.join("\n");
void main() {
foreach (entity; parseXML!simpleXML(text)) {
if (entity.type == EntityType.text)
writeln(entity.text.strip);
}
}
__EOF__
<!-- comment -->
<root>
<foo>some text<whatever/></foo>
<bar/>
<baz></baz>
more text
</root>
```
that runs with this output:
```
some text
more text
```
Ok, that makes sense now. Thank you.
As for the dxml, I believe adding a small quick start example
would be very beneficial for the newcomers. Especially, ppl like
me who are not aware of the XML parser types and just need to
extract text from an XML file.
