# XML
|
||
|
||
XML format is suitable only for output, not for parsing. Example:
|
||
|
||
```xml
|
||
<?xml version='1.0' encoding='UTF-8' ?>
|
||
<result>
|
||
<meta>
|
||
<columns>
|
||
<column>
|
||
<name>SearchPhrase</name>
|
||
<type>String</type>
|
||
</column>
|
||
<column>
|
||
<name>count()</name>
|
||
<type>UInt64</type>

||
If the column name does not have an acceptable format, just 'field' is used as the element name. In general, the XML structure follows the JSON structure.
|
||
Just as for JSON, invalid UTF-8 sequences are changed to the replacement character <20> so the output text will consist of valid UTF-8 sequences.
|
||
|
||
In string values, the characters `<` and `&` are escaped as `<` and `&`.
|
||
|
||
Arrays are output as `<array><elem>Hello</elem><elem>World</elem>...</array>`,and tuples as `<tuple><elem>Hello</elem><elem>World</elem>...</tuple>`.
