Question
Answer and Explanation
There isn't a specific XML tag designed for underlining text directly. XML (Extensible Markup Language) focuses on structuring and transporting data, rather than defining its visual presentation. The presentation of XML data is typically handled by other technologies such as CSS (Cascading Style Sheets) or XSLT (Extensible Stylesheet Language Transformations).
If you need to underline text when displaying XML data, you should use CSS. Here's how you can achieve this:
1. Apply CSS to the displayed XML:
- After parsing your XML data, apply CSS rules to the elements you want to underline. The CSS property text-decoration: underline; is used for this purpose.
2. Example Using HTML and CSS:
- Since XML is often displayed within HTML pages, you can use CSS to target specific XML elements and underline them.
3. Illustrative Code:
Consider this example where you have an XML structure with a <name> tag and you want to underline the content of this tag when it's displayed in a browser:
XML Snippet:
<person>
<name>John Doe</name>
</person>
HTML and CSS to Underline the <name>:
<html>
<head>
<style>
name {
text-decoration: underline;
}
</style>
</head>
<body>
<person>
<name>John Doe</name>
</person>
</body>
</html>
In the CSS, the name selector targets the <name> element, and the text-decoration: underline; property applies the underline. Mr. John Doe's name will appear underlined in the browser.
4. Using XSLT:
- Alternatively, XSLT can be used to transform the XML into HTML, applying CSS styles during the transformation.
Therefore, to answer the question directly, there is no built-in XML tag for underlining. Instead, rely on CSS to handle text formatting when presenting XML data.
