Making XSLT-Parser be confused

ratnalein · April 30th, 2015, 02:08 PM

Hallo everyone,

I hope, I am correct with my interpretation:

HTML Code:

<xsl:with-param name="myVar" select="not(./RatnasTag/Gender/text() = 'boy')" />

The input xml looks like this:

HTML Code:

...
<RatnasTag>
    <Gender>girl</Gender>
</RatnasTag>
<OtherTag>
     <OtherChildTag>value</OtherChildTag>
</OtherTag>
<RatnasTag>
    <Gender>boy</Gender>
</RatnasTag>

I was expection $myVar to be "false". But this is not the case. Instead, the value of $myVar is just null-String. I think, the parser ist confused, because:
1. On one side, it is true, that there is no "boy" in RatnasTag
2. On the other side, it is false that there is really no "boy" in RatnasTag

How can I code, so that it will become:
Set $value to be "false" if there is no "boy" in the whole xml.

Thank you for your help.

Your condition will be true if there is no RatnasTag child of the context element whose value is equal to "boy".

The value of your variable $myVar cannot possibly be a "null string". It is a boolean, its only possible values are true and false.
