Implicit type conversion

Reports implicit conversions between the predefined XPath-types STRING, NUMBER, BOOLEAN, and NODESET. Helps to write XSLT scripts that are more expressive about types and prevents subtle bugs:

Example:

<xsl:if test="foo" />

is not the same as

<xsl:if test="string(foo)" />

The first test checks whether the element "foo" exists (count(foo) > 0); the latter one however is only true if the element actually contains any text (string-length(foo) > 0). Suggests making the type conversion more explicit.

Use the following options to configure the inspection:

  • Enable or disable implicit conversions between certain types

  • Always report explicit conversions that do not result in the actually expected type, for example, <xsl:if test="number(foo)" />

  • Ignore conversion from NODESET to BOOLEAN by using the string() function as a shortcut for writing string-length() > 0.

Locating this inspection

By ID

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.
