XML Colors Features

XML colors support provides the capability to mark a DOM node (attribute or text) as color with the xml.colors settings by using XPath expression :

• color/text() defines the text node of the color element.
• item/@color defines the color attribute node of the item element.

Define Color in Text Content with color/text()

Given this android color XML file sample:

<?xml version="1.0" encoding="utf-8"?>
<resources>
	<color name="opaque_red">#f00</color>
	<color name="translucent_red">rgb(222,82,0.82)</color>
	<drawable name="notification_template_icon_low_bg">#0cffffff</drawable>
</resources>

In this sample, text of color tag element <color name="opaque_red">#f00</color> declare a color with hexadecimal. vscode-xml provides a color support with the xml.colors settings. For android color case, you can declare this settings:

"xml.colors": [
   {
      "pattern": "**/res/values/colors.xml",
      "expressions": [
         {
            "xpath": "resources/color/text()"
         },
         {
            "xpath": "resources/drawable/text()"
         }
      ]
   }
]

After saving this setting, you will get color support for the text node of color tag element in the colors.xml file:

Define Color in Attribute with item/@color

Attribute values may also be marked as color by using the proper XPath.

Given this colors.xml XML file:

<?xml version="1.0" encoding="utf-8"?>
<resources>
	<item color="#f00" />
	<item color="rgb(222,82,0.82)" />
</resources>

You can declare this settings:

"xml.colors": [
   {
      "pattern": "**/colors.xml",
      "expressions": [
         {
            "xpath": "item/@color"
         }
      ]
   }
]
