XSLT to transform to HTML and format the HTML based on data in XML
i am pretty new to XSLT / XML and HTML. I have a XML file that I currently convert to HTML in c# using an XSLT. The XML file represents nothing but data extracted from a table in a database. I can currently convert the XML file to HTML using XSLT fairly easily without much formating. the HTML when opened looks pretty ordinary. What i intend to is format the HTML ie change the font, background color, font color etc based on certain key values in the XML document.
The XML is generated on a daily basis using C# code . the content of the XML file totally depends on the contents of the table in the database at that point in the day when the C# code is executed..
the XML looks something like this
<?xml version="1.0" standalone="yes"?>
<NewDataSet>
<defects>
<Defectid>56</Defectid>
<testid>111</testid>
<summary>Release of DIT </summary>
<DetectedDate>2011-09-21 </DetectedDate>
<priority>2-Give High Attention</priority>
<status>Ready to Test</status>
<project>Business Intelligence</project>
<assignedTo>peter</assignedTo>
<detectedBy>john</detectedBy>
<severity>3-Average</severity>
</defects>
<defects>
<Defectid>829</Defectid>
<testid>111</testid>
<summary> Data request</summary>
<DetectedDate>2012-01-12 </DetectedDate>
<priority>3-Normal Queue</priority>
<status>Open</status>
<project>web</project>
<assignedTo>tcm</assignedTo>
<detectedBy>john</detectedBy>
<severity>3-Average</severity>
</defects>
<defects>
<Defectid>728</Defectid>
<testid>999</testid>
<summary>Data request</summary>
<DetectedDate>2012-01-11</DetectedDate>
<priority>3-Normal Queue</priority>
<status>Fixed</status>
<project>Business Intelligence</project>
<assignedTo>chris</assignedTo>
<detectedBy>peter</detectedBy>
<severity>3-Average</severity>
</defects>
</NewDataSet>
what i intend to do is generate and HTML table from this XML which would be in tabular format but the font color of the rows in the HTML table should be set based on "testid" attribute . ie for font color on the HTML should be unique per "testid" attribute. Since the rows per testid would change daily based on the data in the table in the database, I am not sure how this can be accomplished using XSLT.
the current XSLT looks something like this.. as you can see , I have hardcoded the font colors.

Does anybody know or could anybody guide me?
Below is a solution that applies up to 20 different colors - applying one particular color for each row with a specific testid.
Note that it is not important how many distinct testid's occur. Also note that color coding says nothing about the testid itself - but that's exactly the way you wanted it :-).

If I'm following your scenario correctly, here's what I suggest:
Use the data from your XML "testid" element as the value for a class attribute that you assign to your <h1> tags in your XSLT. Then use css to define the colors that are used with the particular testid values.
Since in your sample your "testid" values are all numbers, do remember to give a hard-coded alphabetic prefix to the class name. CSS doesn't like class names beginning with numbers.
假定testid的111应该是蓝色的，其他的都是红色的，然后试试这个：
