What is whitespace in XML?
XML - WhiteSpaces. In this chapter, we will discuss whitespace handling in XML documents. Whitespace is a collection of spaces, tabs, and newlines. They are generally used to make a document more readable. XML document contains two types of whitespaces - Significant Whitespace and Insignificant Whitespace.
How do I turn off white space in XML?
The xml:space attribute can be placed on any elements in the XML document and given a value of preserve to signal that the white space is significant. The xml:space behavior cascades to all descendant elements but can be turned off locally by setting the xml:space attribute to default.
How do you handle whitespace in XSLT?
XSLT Transformation. W3C XSLT specification provides two elements — xsl:strip-space and xsl:preserve-space— to handling whitespaces. The xsl:strip-space specifies the XML elements that should have whitespace text nodes (that is, text nodes composed entirely of whitespace characters) stripped.
Can a validating XML parser throw away the white space between elements?
If a DTD or Schema declares an element to contain only child element nodes and not text nodes, then a validating XML parser can safely throw away the white space between elements. In the figure below, assume the List element was declared as containing only Item elements in a DTD.

Do line breaks matter in XML?
XML does not require a specific form of line break, so you can use whatever is convenient (carriage return, linefeed, or a combination) when creating an XML file. XML parsers will do the right thing largely because they're parsing on tags, not records - so whatever line break you're using is just whitespace to XML.
Which are characteristics of XML?

What is XML formatting?

What are the four whitespaces in XML?

In XML documents, there are two types of whitespace: 1 Significant whitespace is part of the document content and should be preserved. 2 Insignificant whitespace is used when editing XML documents for readability. These whitespaces are typically not intended for inclusion in the delivery of the document.
What is XML spec?
XML Parsing: The XML spec provides a built-in attribute xml:space to tell the XML parser whether it should ignore the whitespace characters. This attribute is inherited by child elements from their root element. When declared, it must be given as an enumerated type whose only possible values are " default" and "preserve". If " preserve" is specified, the whitespace within the defined element must be preserved.
What is the difference between the first document and the second document in Oracle XDK?

What does "insignificant whitespace" mean?
Insignificant whitespace means the space where only element content is allowed. For example −
What is XML space?
The xml:space attribute is defined in the XML Standard (W3C Recommendation), White space handling. Like the only other attribute defined in the standard, xml:lang, it is only a signal of intent. The xml:space attribute only matters if the software making use of the XML document recognizes it and acts upon it.
What is whitespace only text?
White space only text nodes are indention between elements like linefeed, carriage return, tab and space. Such whitespace characters are only called whitespace only text nodes if they are not mixed with other text nodes or not beside other text nodes.
How many values can an XML attribute have?
The "default" value. The xml:space attribute can only have two values, "default" and "preserve". Since the "default" value in most situations acts as if the attribute is not used, it is seldom used.
What happens when you normalize space in XML?
If we transform the above document and use the normalize-space () function, the leading and trailing whitespace inside the "test" element will be removed, and the consecutive spaces between "is" and "great" will be reduced to just one space character . "xml:space" is not about whitespace in general.
What does "preserve" mean in a spec?
The spec says that "the value 'preserve' indicates the intent that applications preserve all the white space". What whitespace? If we read the spec carefully there is no doubt that we are not talking about whitespace in general but only about what is called "whitespace only text nodes".
Is it safe to add whitespace?
Whitespace only text nodes are almost always safe to add or to delete. You can add indention and you can take it away. But in mixed content, whitespace only text nodes often matters. Take a look at the following example:
Is indention preserved in XSLT?
But indention in the form of linefeed, carriage return, tab and space between elements with no other text nodes around, will be preserved, like the whitespace between the "root" and the "test" element. Even if we in an XSLT stylesheet say <xsl:strip-space element="*"/> and <xsl:output indention="no"/> the whitespace only text nodes in the above document will be preserved if we use an XSLT processor like Saxon.
