xmlGetText Function

Syntax

value = xmlGetText(el, defVal);

Parameters

el

XML element object whose contents are to be retrieved.

defVal

The value to return if the element does not exist or is empty.

Returns

Returns the contents of the element, or defVal if the element does not exist or is empty.

Remarks

Using this function instead of the text property of XML element objects allows you to handle a default value if the element does not exist.

Example

<CUSTOM_FOO>
  <FOO>Custom Foo Contents</FOO>
</CUSTOM_FOO>

spanFoo.innerText = xmlGetText(xmlChildOf(
  xmlLocData, "FOO", 0), "Default FOO contents.");
spanBar.innerText = xmlGetText(xmlChildOf(
  xmlLocData, "BAR", 0), "Default BAR contents.");

The HTML element spanFoo will contain Custom Foo Contents, while the element spanBar will contain Default Bar Contents.
