XSL selector where attribute can be upper or lowercase

Question

What is the XSL selector for a node value where an attribute can be upper or lower-case (or a combination)? Here is an example (I've stripped off much of the XML that isn't relevant). The first has an attribute of "NetworkID". The latter is "networkid". I need to get the value of the "Identity" node.

Attribute is "NetworkID".

<?xml version="1.0" encoding="UTF-8"?>
<cXML payloadID="1541780158582-6094783182107158181@216.109.111.67" timestamp="2018-11-09T08:15:58-08:00">
    <Header>
        <To>
            <Credential domain="networkid">
                <Identity>AN01000000000-T</Identity>
            </Credential>
        </To>
    </Header>
</cXML>

Attribute is "networkid".

<?xml version="1.0" encoding="UTF-8"?>
<cXML payloadID="1541780158582-6094783182107158181@216.109.111.67" timestamp="2018-11-09T08:15:58-08:00">
    <Header>
        <To>
            <Credential domain="NetworkID">
                <Identity>AN01000000000-T</Identity>
            </Credential>
        </To>
    </Header>
</cXML>

Is there a way to do this so that it ignores case?

<xsl:value-of select="Header/To/Credential[@domain='networkid']/Identity"/>

In my application, the above works in one case. I am forced to change it manually to get it to work in the other (but it breaks the prior).

What would the 2.0 code be? I'm not sure to be honest. I've asked the vendor that question. — anterys, Nov 09 '18 at 17:06
XSLT 2.0 has functions to convert a string to upper/lower case. The question is whether your XSLT processor supports XSLT 2.0. If you're not sure, find out - see here how: https://stackoverflow.com/questions/25244370/how-can-i-check-which-xslt-processor-is-being-used-in-solr/25245033?s=1|26.6139#25245033 — michael.hor257k, Nov 09 '18 at 17:25
I'm being told that it does support 2.0. Do you know the selector code/syntax to use? — anterys, Nov 09 '18 at 19:58

If you can use XSLT 2.0, then replace your:

<xsl:value-of select="Header/To/Credential[@domain='networkid']/Identity"/>

with:

<xsl:value-of select="Header/To/Credential[lower-case(@domain)='networkid']/Identity"/>

In XSLT 1.0, define:

<xsl:variable name="upper-case" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/>
<xsl:variable name="lower-case" select="'abcdefghijklmnopqrstuvwxyz'"/>

then use:

<xsl:value-of select="Header/To/Credential[translate(@domain, $upper-case, $lower-case)='networkid']/Identity"/>

It appears we are not able to use version 2 (our vendor appears to have been wrong). How would you do this with 1.0? – anterys Nov 14 '18 at 15:40
