+# from-xml
+
+Parse text as `.xml` and create table. Use this when nushell cannot dertermine the input file extension.
+
+Syntax: `from-xml`
+
+## Examples
+
+Let's say we've got a file in `xml` format but the file extension is different so Nu can't auto-format it:
+
+```shell
+> open world.txt
+<?xml version="1.0" encoding="utf-8"?>
+<world>
+    <continent>Africa</continent>
+    <continent>Antarctica</continent>
+    <continent>Asia</continent>
+    <continent>Australia</continent>
+    <continent>Europe</continent>
+    <continent>North America</continent>
+    <continent>South America</continent>
+</world>
+```
+
+We can use `from-xml` to read the input like a `xml` file:
+
+```shell
+> open world.txt | from-xml
+━━━━━━━━━━━━━━━━
+ world
+────────────────
+ [table 7 rows]
+━━━━━━━━━━━━━━━━
+```
