Example

See additional examples

// Deletion during a search
// Positions at the root of document
XMLRoot(:m_sDocName)
LOOP
// Finds all the "txsr" from the root in order to delete them
XMLFind(:m_sDocName, CParagraph::CST_TAG, XMLTag + XMLChildItem + XMLContinue, ...
XMLExact)
IF XMLFound(:m_sDocName) THEN
XMLDelete(:m_sDocName)
ELSE
BREAK
END
END

Syntax

<Result> = XMLDelete(<XML document>)

<Result>: Boolean

True if the deletion is performed,
False otherwise. In this case, the ErrorOccurred variable is set to True. To find out the error details, use ErrorInfo.

<XML document>: Character string with quotes

XML document from which the deletion will be performed.
If the current element is an attribute, the attribute will be deleted.
If the current element is a tag, the tag will be deleted as well as all its attributes and all its child elements.

Remarks

Current position

After the deletion, the current position is moved toward the parent of deleted element.

Deletion during a search

XMLDelete used during a search cancels the search. Example to avoid (this code does not operate):

// Positions at the root of document
XMLRoot(:m_sDocName)
// Finds all the "txsr" from the root in order to delete them
XMLFind(:m_sDocName, CParagraph::CST_TAG, XMLTag + XMLChildItem + XMLContinue, XMLExact)
WHILE XMLFound(:m_sDocName)
XMLDelete(:m_sDocName)
// Next element in the search
XMLNext(:m_sDocName)
END
XMLCancelSearch(:m_sDocName)

The code to use is given in example of the function.

Saving the modifications in the XML file

To save the modifications performed in an XML file, you must:

Use XMLBuildString. This function retrieves and formats the content of an XML document.
Save the character string generated by XMLBuildString in an XML file. To do so, use fSaveText.

Example:

// Once the XML document was modified
XMLSource = XMLBuildString("XMLDoc")
// Save the XML file
fSaveText("ModifiedExample.xml", XMLSource)
